[Splenic infarction in Plasmodium falciparum malarial attack].

Splenic infarct during P. falciparum malaria is rare but well known. We report one case where ultrasonography and computed tomography suggested the diagnostic, showing respectively in splenic parenchyma a peripheral hypoechoic lesion and a low attenuation lesion. Diagnostic was confirmed by spontaneous regression during following days. We shall encounter more frequently than nowadays this rare entity due to expanding tourism and P. falciparum resistance.

Pseudoaneurysm and splenic infarction in chronic pancreatitis--a case report.

Peripancreatic pseudoaneurysm and splenic infarction are rare but life-threatening complications of chronic pancreatitis. The incidence of pseudoaneurysm in patients who undergo angiography for pancreatitis is about 10%. Clinically, pseudoaneurysm is hard to discover until rupture occurs. The authors have recently experienced a case of intact pseudoaneurysm and splenic infarction in chronic alcoholic pancreatitis. A bolus enhanced CT scan and angiography were essential to confirm these complications of pancreatitis. We managed these complications successfully by distal pancreatectomy and splenectomy.

Massive splenic infarction in cirrhosis: report of a case with spontaneous disappearance of hypersplenism.

A cirrhotic patient with massive splenic infarction is described. Celiac angiography showed normally opacified splenic artery and vein and a markedly enlarged spleen with large avascular zones. Splenic infarction was associated with the spontaneous disappearance of a syndrome of hypersplenism. The spleen was surgically removed. Histological examination showed multiple thromboses of the small arterial and venous vessels. The cause of this infarct remained unclear.

Non hypoxia-related splenic infarct in a patient with sickle cell trait and infectious mononucleosis.

Splenic infarction in patients with sickle cell trait is usually related to hypoxic conditions, while non-hypoxia-related infarcts are extremely rare. We report on a case of a 17-year-old male patient, living at sea level, who developed a severe left upper quadrant abdominal pain during the course of a febrile episode. On physical examination he had a mildly palpable but extremely painful spleen. A spleen scan revealed 2 areas of impaired radionucleide distribution. Hepatic enzymes were moderately increased and the IgM anti-EBV antibodies positive. Hemoglobin electrophoresis revealed the presence of 42% of hemoglobin S. A probable diagnosis of splenic infarction was established in a patient with sickle cell trait, during the course of infectious mononucleosis. The patient was treated symptomatically. The conditions of splenic congestion induced by the EBV infection and the high-grade fever may have contributed to splenic sequestration and subsequent infarcts.

Splenic infarct presenting as acute abdominal pain in an older patient.

A 67-year-old female presented to the Emergency Department with a several hour history of severe pain in the left upper quadrant. A computed tomographic study (CT scan) of the abdomen demonstrated a splenic infarct. The patient was subsequently found to have a patent foramen ovale, with a small right-to-left shunt. This patient's splenic infarct is considered to be embolic in etiology, either from the patent foramen ovale or severe atherosclerotic disease. Patients with left upper quadrant pain who do not have the etiology differentiated by initial testing should be considered to have the potential for splenic infarction. This case illustrates the uncommon occurrence of splenic infarction, presenting as left upper quadrant pain.

[Contribution of sectional imaging, echography and MRI, for the diagnosis of splenic infarction in Osler endocarditis. Apropos of a case].

A case of symptomatic splenic infarct in an 11 year-old girl suffering from bacterial endocarditis is reported; this occurrence is a rare and serious condition in this disease. The diagnosis of haemorrhagic splenic infarct was suggested by ultrasonography and confirmed by MRI. No splenic abscess developed and this was correlated to a rapid improvement of the clinical state following an antibiotic treatment only. The authors discuss the role of sonography and MR in the etiologic diagnosis of splenic involvement in patients suffering from bacterial endocarditis.

Hepatic and splenic infarctions: complications of therapeutic transcatheter embolization.

Two cases are described in which therapeutic transcatheter Gelfoam embolization was complicated by fatal hepatic infarction in one patient and splenic infarction with abscess formation in another patient. These are unusual complications of this widely used therapeutic technique. The probable pathophysiology of these complications is discussed and suggestions for managing and avoiding them are made.

Splenic infarction, a complication of transcatheter hepatic arterial embolization for liver malignancies.

Splenic infarction was recognized in five of 37 patients who had hepatic neoplasms and who were being examined after transcatheter hepatic arterial embolization by CT during a follow-up study. CT images of the spleen showed multiple low density areas of a wedge or fused-wedge shape in most patients and of a rod or round shape in others. These low density areas decreased in size in time, and in two patients they disappeared in three months. Three of the five patients complained of a dull pain in the left upper quadrant that did not require any treatment. CT is effective in the diagnosis and assessment of splenic infarction. Awareness of this complication will help to avoid it when hepatic arterial embolization is being performed.

Asian variant of CD5+ intravascular large B-cell lymphoma with splenic infarction.

A 57-year-old man was admitted with fever and epigastralgia, and presented with splenomegaly and pancytopenia. A CT scan revealed splenic infarctions. There were no lymphadenopathies, skin lesions, or neurological abnormalities. A splenectomy was performed. Bone marrow involvement with hemophagocytosis was noted. The diagnosis of Asian variant of intravascular diffuse large B-cell lymphoma was based on intravascular and sinusoidal distribution of large CD5+ B cells. The patient died of the disease 11 months after onset. To our knowledge, this is the first report of AIVL that presented with splenic infarction. This distinct lymphoma should be included in the differential diagnosis of splenic infarction.

[Diagnosis of acute splenic infarction by echo-signal-enhanced ultrasound].

HISTORY AND CLINICAL FINDINGS: A 35-year-old patient with known mitral valve endocarditis presented with a stabbing pain in the left upper abdomen (patient 1). A 79-year-old patient with a history of chronic lymphocytic leukaemia (CLL) and aortic valve replacement presented with acute left upper quadrant, chest pain and impaired vision (patient 2). INVESTIGATIONS: An abdominal ultrasound revealed nonhomogeneous hypoechoic splenic lesions in both patients, which were classified as extended splenic infarctions by echo enhancer studies. The diagnosis was confirmed by computed tomography. Transesophageal echocardiography showed extensive mitral valve vegetations in patient 1. Patient 2 had a progression of the CLL without evidence of endocarditis. Magnetic resonance imaging of the brain showed infarction of the posterior cerebral artery area. DIAGNOSIS, TREATMENT AND COURSE: Patient 1: Mitral valve endocarditis with embolic splenic infarction. Patient 2: Progressive CLL with thrombotic splenic and brain infarction. In patient 1, mitral valve replacement was performed. In patient 2, chemotherapy was initiated and she was started on low molecular weight heparin s. c. and aspirin. No further embolic or thrombotic complications occurred. No splenectomy was performed. CONCLUSION: A splenic infarction is a complication pointing towards an underlying serious disorder. Echo-enhanced ultrasound is as sensitive as computed tomography for early diagnosis. Splenic infarction should trigger urgent treatment of the underlying condition.

Recovery of splenic infarction with anti-platelet treatments and platelet-apheresis in polycythemia vera.

Thrombo-embolic events in coronary and peripheral arteries, and cerebral, pulmonary, portal, hepatic, and deep veins are seen in 27-45% of patients with polycythemia vera (PV). A 79-year-old man was admitted with complaints of pruritus increasing after bath and left upper abdominal pain radiating to left shoulder for two months. On physical examination, ruddy and hyperemic appearances of his face and conjunctiva, tenderness on the left upper quadrant, and splenomegaly were noted. Hemoglobin level was 16.6g/dl, hematocrit 53.8%, white blood cell count 26x10(9)/l, and platelet count 1.032x10(9)/l. Bone marrow aspiration and biopsy revealed hypercellularity, megakaryocytic hyperplasia and dysplasia. The leukocyte alkaline phosphatase score was 190. The levels of serum vitamin B12 and D-dimer were 316 pg/ml and 744 ng/ml, respectively. Arterial O2 saturation was 96%. Red cell mass was measured as 43 ml/kg using radionuclide 51Cr labelled erythrocyte scintigraphy. On cytogenetic analysis, deletion of 20q was found. Computed tomography of whole abdomen showed diffuse splenomegaly and two hypodense areas indicating splenic infarction in 2.5x2 and 3.5x3 cm diameters in subcapsular localization of the spleen. The patient was treated with therapeutic platelet-apheresis, 40 mg/day aspirin, analgesic drugs, and 3g/day hydroxyurea. After 1.5 months, platelet counts dropped to less than 500x10(9)/l and splenic infarcts were not detected on computed tomography. Splenic infarction may be the first evidence of thrombosis in PV. The reduction of platelet counts with platelet-apheresis, anti-platelet drugs, and careful clinical observation may be satisfactory in the treatment of splenic infarction.

[Suppurating splenic infarction originating from endocarditis].

Three cases of splenic infarction complicated by abscess formation during bacterial endocarditis are reported. In all three cases there were associated clinical abdominal signs and, in one case, there was persistently positive hemocultures. The diagnosis was made by CAT scanning. The three patients underwent splenectomy and one patient also underwent valve replacement the same day. The methods of early diagnosis of splenic complications during endocarditis and the indications of splenectomy are discussed. Ultrasonography and abdominal CAT scanning are the most sensitive diagnostic methods for splenic lesions. As splenic rupture is associated with a high mortality and this complication may occur at any time during infarction complicated by abscess formation, early splenectomy is justified when abdominal clinical signs are elicited associated with a persistent, infectious syndrome with or without positive blood cultures, under appropriate antibiotic therapy. Splenectomy should also be considered if valve replacement is carried out in the same circumstances to avoid infection of the prosthesis.

[Splenic infarcts in Goodpasture's syndrome: its significance for diagnosis, prognosis, and treatment (author's transl)].

Necrotising splenic arteritis with numerous extensive anaemic splenic infarcts was found in four cases of Goodpasture's syndrome with the necrotising variant of rapidly progressive glomerulonephritis. The disease was rapidly fatal. Early scanning of splenic infarcts for diagnostic, prognostic and therapeutic purposes of the fulminating form of Goodpasture's syndrome is recommended.

Sonographic patterns in splenic infarct.

The sonographic findings in eight cases of splenic infarct at their onset and at different phases of their development have been retrospectively analyzed. A wide range of appearances was seen (single or multiple, rounded or wedge-shaped, echo-free, hypoechoic, and hyperechoic lesions). In our opinion, such variable appearances are related to the age of the infarct (hypoechoic or echo-free in the earlier stages, hyperechoic in healed infarcts). A presumptive diagnosis is possible in the earlier stages since the detection of changes (in echogenicity and/or in size) over a period of time strongly suggests an infarct. On the other hand, a hyperechoic wedge-shaped lesion is fairly typical of healed infarcts.

Primary antiphospholipid syndrome presenting with abdominal angina and splenic infarction.

The antiphospholipid syndrome is an autoimmune hypercoagulability syndrome in which a wide variety of thromboembolic diseases may occur. Gastrointestinal manifestations associated with vascular occlusion include Budd-Chiari syndrome, hepatic and splenic infarction, pancreatitis, omental and intestinal infarction, and esophageal variceal bleeding due to portal vein thrombosis, but chronic mesenteric ischemia associated with mesenteric arterial thrombosis is very rare in this syndrome. We experienced a female patient with primary antiphospholipid syndrome with abdominal angina and splenic infarction associated with celiac trunk and mesenteric arterial thromboses. This is the first report describing chronic mesenteric ischemia and splenic infarction in a patient with primary antiphospholipid syndrome.

Splenic infarction during acute malaria.

Malaria is the most frequent cause of fever among travellers returning from tropical countries. Each year about 7000 cases are notified in France, of which 90% are due to Plasmodium falciparum. We describe the case of a Caucasian female patient with no previous exposure to malaria in whom splenic infarction occurred during effective antimalarial treatment for initially uncomplicated acute malaria. Management was restricted to close clinical monitoring and analgesia (subcutaneous morphine). Imaging abnormalities resolved within a few months. We found seven other such cases in the literature. All seven patients were younger and splenic infarction occurred later than in the case we describe. Clinical outcome was favourable in all the cases. It is noteworthy that this rare complication can occur despite appropriate antimalarial prophylaxis and treatment. There are no known predictive signs. Clinicians must be aware that left hypochondrial pain occurring during treatment for acute malaria may be due to splenic infarction.

Pulmonary embolism and splenic infarction in a patient with sickle cell trait.

A 43 year-old black man with sickle cell trait documented by hemoglobin electrophoresis presented with severe pleuritic chest pain and hypoxemia three weeks after discharge following abdominal surgery. A pulmonary embolus was diagnosed by angiography and he was treated with heparin; the minimum arterial pO2 was 55 torr while O2 was being administered at a rate of 3 L/min. During this therapy, he developed abdominal pain. Computerized tomography suggested splenic infarction, which was documented by radionuclide liver-spleen scan and magnetic resonance imaging (MRI); the patient's spleen had been normal at exploratory laparotomy three weeks previously. No source for emboli was identified in the deep venous system by MRI. Although splenic infarction has been reported in patients with sickle cell trait at high altitude, this is the first reported case of splenic infarction secondary to the hypoxemia of pulmonary embolism in a patient with sickle cell trait. The spleen is subject to infarction in sickle cell trait because blood flow is slow through a hypoxemic and acidemic environment. The additional hypoxemia due to pulmonary embolism is presumed, in our patient, to have created a local splenic environment which permitted infarction to occur.

Isolated splenic infarction following left cardiac catheterization: case report and a review of the literature.

A cardiac catheterization was performed in a 57-year-old man for post-infarction angina. A severe left flank pain developed following the angiography. Ultrasonography, computed tomography, and radionuclear scanning of the abdomen showed splenic infarction. An isolated cholesterol atheroembolism of spleen from disrupted atheromatous plaques so far has not been reported.
