[Mechanical small bowel obstruction due to bezoars: correlation between CT and surgical findings].

PURPOSE: To evaluate the correlation between computed tomography (CT) and surgery, for the diagnosis of bezoar in small bowel obstruction. To analyze the predisposing etiologic factors in this population. PATIENTS AND METHODS: We reviewed retrospectively between 1994 and 1999, 12 patients whose final diagnosis was small bowel obstruction with bezoar. All patients underwent helical CT scan before treatment. Eight patients were treated by surgery and 4 recovered with gastric aspiration. RESULTS: Small bowel obstruction was diagnosed by CT which always demonstrated a transition zone with ovoid intraluminal mass outlined by the bowel wall. The mass consisted of a mixture of soft tissue and internal gas bubbles like feces, suggesting bezoar. Surgery confirmed small bowel obstruction and presence of bezoar. Predisposing factors were: partial gastrectomy (2/12), post surgical adhesions (7/12), Meckel diverticulum (1/12) and dietary factors. CONCLUSION: We agree with the authors of the few prior CT reports and suggest that the characteristic CT appearance of mottled gas pattern is pathognomonic of bezoar with an excellent correlation in our population.

Bilateral internal carotid agenesis: value of CT angiography and correlation to embryogenesis.

Bilateral internal carotid artery agenesis is an uncommon disease, difficult to differentiate from bilateral carotid artery thrombosis. A few case reports have described the contribution of conventional angiogram to make the diagnosis and recognize the anatomic details of this rare malformation. Advantages of CT angiography as a non-invasive radiologic tool are discussed in this case report.

Ultrasonography of chronic inflammatory bowel diseases.

Advances in the understanding of bowel appearances with high-resolution sonography have led to consideration of this technique as an important tool for bowel disease assessment. Ultrasonography may display the transformation of the intestinal wall from normal to pathological state in inflammatory diseases. Furthermore, intestinal ultrasonography may serve as a diagnostic clue if typical patterns of the bowel wall are demonstrated. Thus, Crohn's disease, ulcerative colitis, diverticulitis, or infectious ileocolitis may be specifically demonstrated in the majority of cases. Besides showing the parietal signs of inflammation, ultrasonography also shows the perigut abnormalities and may demonstrate complications such as fistulas and abscesses. Finally, with the help of Doppler, some additional information may be obtained about the activity of chronic inflammatory diseases. In clinical practice, used in combination with other imaging modalities, such as CT or endoscopy, bowel ultrasonography appears to be a non-invasive and effective diagnostic tool for the diagnosis and follow-up of Crohn's disease and ulcerative colitis.

Septic arthritis of the spine facet joint: early positive diagnosis on magnetic resonance imaging. Review of two cases.

We report two cases of septic arthritis of the spine facet joint in two patients with no previous medical history. Clinical symptoms were consistent with a spondylodiscitis. Blood cultures were positive for Staphylococcus aureus. The infection was initially shown and precisely localised with magnetic resonance imaging, despite an initially negative or aspecific bone scintigraphy. Magnetic resonance imaging of the spine demonstrated infection involving the epidural space and paraspinal musculature and enhancement of the infected thoracic and lumbar facet joint after gadolinium injection.

[MR cholangiography in biliary complications after liver transplantation in children].

PURPOSE: To evaluate the role of MR Cholangiography in a pediatric population with biliary complications after liver transplantation and particularly with anastomotic stenosis. PATIENTS AND METHODS: Ten MR cholangiography studies were performed in 10 children with liver transplant who were suspected of having biliary complications between December 1996 and April 1998. The findings on MR were correlated with the results from liver biopsy, liver ultrasound, liver function tests and with clinical information when available. RESULTS: MR cholangiography identified 9 children with biliary tree dilatation, 4 with anastomotic stenosis, 5 with multiple bile ducts stenosis, 2 with stones in the intra-hepatic biliary tree and 2 with abnormalities suspicious for acute cholangitis. Three of 4 anastomotic stenoses were confirmed and treated by percutaneous cholangiography. There was no correlation between the different exams in 6 children but MR cholangiography confirmed the final diagnosis. CONCLUSION: In children with liver transplantation, MR cholangiography may be useful to evaluate and to confirm a diagnosis of bile duct complications and it is helpful in the absence of correlation between liver biopsy, ultrasound and liver function test.

MRI of the pulmonary veins: comparison between 3D MR angiography and T1-weighted spin echo.

OBJECTIVE: The purpose was to determine the ability of three-dimensional (3D) magnetic resonance (MR) angiography to depict normal pulmonary veins in comparison with spin-echo MR imaging. MATERIALS AND METHODS: MR imaging of 40 patients with cardiovascular disease were reviewed. Patients with known pulmonary venous abnormalities were excluded. Using a standard GE 1.5-T magnet, axial T1-weighted spin-echo 5-mm-thick contiguous slices and 3D MR angiography (contiguous slice thickness of 2.5-3.5 mm, 20-30 c.c. of gadolinium bolus at 1-1.5 c.c./sec, 32-43-second breath-hold, coronal and sagittal plane acquisition) were evaluated retrospectively on separate occasions by two experienced radiologists. Multiplanar imaging projection was used for the identification of pulmonary veins. Each lung was considered to have two drainage veins: a superior vein and an inferior vein. Identification of a pulmonary vein was made by visualizing a connection with the left atrium. RESULTS: 143 pulmonary veins (87.5% +/-5.2) were identified at the level of the left atrium on T1-weighted spin-echo images, and 157 (98.1% +/-1.9) were identified on 3D MR angiography (p<0.01). Overall we identified by T -weighted spin-echo imaging 36 right upper, 38 right lower, 27 left upper, and 38 left lower pulmonary veins. By 3D MR angiography, we identified 38 right upper, 40 right lower, 39 left upper, and 40 left lower pulmonary veins. All four pulmonary veins were detected in 22 patients on spin-echo imaging (55%) and in 37 patients (92.5%) on 3D MR angiography (chi = 3.81, p<0.05). CONCLUSION: A significant difference is demonstrated between 3D MR angiography and spin-echo MR imaging in identifying normal pulmonary veins. MR angiography provides a complete view of normal pulmonary venous anatomy and could be a valuable tool for the assessment of abnormal pulmonary venous drainage.

[Management of aneurysms of the hepatic artery. 15 patients].

OBJECTIVES: There appears to be an increasing number of patients with aneurysm of the hepatic artery. We report a retrospective analysis of management schemes used in a single hospital unit over the last 14 years. PATIENTS AND METHODS: Clinical data on all patients with aneurysm of the hepatic artery, treated in Edouard-Herriot hospital (Lyon, France) from 1985 to 1999, were reviewed. RESULTS: There were 15 patients with 16 aneurysms. Mean patient age was 56 years with no gender predominance. The aneurysm was a fortuitous discovery in 8 of the patients. There were 10 cases of pseudoaneurysm and 6 cases of true aneurysm. Treatment was adapted to the local anatomy and the patient's status. Surgery was used for 5 patients and radiologic embolization for 4. Observation was indicated in 5 patients and spontaneous thrombosis occurred in 1. Mean duration of observation was 24 months. Six patients were lost to follow-up and 2 died from their primary disease. DISCUSSION: Surgery is the treatment of choice for aneurysms situated in an extrahepatic localization while radiologic embolization is appropriate for intrahepatic localizations. Close cooperation between the surgery and radiology teams was most contributive to proper management in our series, providing favorable outcome.
