[Left segmental omental infarction in a child: conservative treatment].

Omental infarction is a rare cause of acute abdomen that usually occurs on the right side. Left omental ischemia is rare in adults and to our knowledge not yet described in children. Its diagnosis, although difficult, is important because it can avoid surgery. We report a case of left segmental omental infarction in an 11-year-old child, diagnosed by imaging studies, treated conservatively, and followed up by ultrasound until complete disappearance of the lesion.

[Regression of Morton neuroma after local injection of steroids].

Morton neuroma is a non neoplastic lesion corresponding to perineural fibrosis encircling the common interdigital plantar nerve. Several therapeutic approaches are possible: conservative treatment or surgery. We report a case treated by local steroid injection where follow-up MR showed near complete regression of the lesion. Although local injection of steroid is a classical treatment, it is the first time to our knowledge that resolution or such a striking diminution of size is reported after infiltration.

[Traumatic perinatal cervical dislocation].

We report on a case of cervical dislocation in which the severity of the lesion contrasts with the paucity of the symptoms. An eight-month-old girl presented with weakness of the left upper limb. She had a normal cephalic delivery. On the following days, increased weakness of the limb showed a spontaneous, partial regression. Clinical examination at eight months showed a normal physical and psychical development, a falling neck and an impossibility to maintain the sitting position, but a normal mobility of the lower limbs. Cervical radiography performed showed a complete dislocation. CT confirmed the diagnosis and eliminated congenital vertebral anomalies. Magnetic resonance imaging showed an important stretching and compression of the spinal cord. Cervical spine damage in the newborn are scarce and serious. The here reported case is characterized by a complete vertebral dislocation associated with medullar stretching and compression, but few initial symptoms.

Adenomyoma of the ampullary region: imaging findings in four patients.

BACKGROUND: We report the imaging features of adenomyoma of the distal common bile duct (CBD) and increase awareness of this rare benign disease. METHODS: Four patients (age range = 66-71 years) with abdominal pain and biliary obstruction had spiral computed tomography (CT) and cholangiography with or without papilla biopsy. Two patients also had endoscopic ultrasound. RESULTS: The CT appearance of adenomyoma was that of a rounded, well-circumscribed, soft tissue mass in the ampullary region, which appeared on cholangiography as a well-defined intraluminal filling defect or caused abrupt and regular stenosis of the CBD. Unfortunately, none of our patients was diagnosed before surgery, and cephalic duodenopancreatectomy was performed in all of them. CONCLUSION: Although imaging findings are not specific, their presence should raise the possibility of a benign tumor. If a proper preoperative diagnosis is made, cephalic duodenopancreatectomy can be avoided.

CT and MR findings of a retrorectal cystic hamartoma confused with an adnexal mass on ultrasound.

We describe the imaging features of a tailgut cyst mistaken for an adnexal mass. A pelvic ultrasound in a 28-year-old woman showed a 10-cm hypoechoic left pelvic mass. Having not seen the left ovary, the radiologist concluded that the mass was an endometrioma. CT disclosed a retrorectal cystic lesion with wall calcifications and internal septa. MR confirmed the extra-ovarian location of the tumor, which was hyperintense on T2-weighted images and had an intermediate signal on T1-weighted images. Surgery revealed a retrorectal cystic hamartoma. Radiological diagnosis of a tailgut cyst requires first correct localization of the tumor and then differentiation from other retrorectal masses.

[Imaging of an aberrant occipital artery arising from the extracranial segment of the internal carotid artery].

We report a case of asymptomatic occlusion of the right internal carotid artery owing to the presence of a rare anatomic variant (occipital artery originating from the extracranial segment of the internal carotid artery). During the preoperative workup for a coronary artery bypass grafting (CABG) in a 65-year-old patient, an occlusion of the right internal carotid artery was visualized on Duplex ultrasound. Distally to the occluded site, the artery was patent thanks to a vessel parallel to it but with a reverse blood flow. MRA and angiography of the brachiocephalic trunk confirmed the occlusion of the internal carotid artery and its opacification distally via an aberrant occipital artery arising at the supra-bulbar level and communicating with the right vertebral artery. Therapeutic abstention was decided and the patient was operated of CABG without any neurological complication. Occipital artery arising from the internal carotid artery is a rare anomaly. Its association with internal carotid artery occlusion may be beneficial because it makes surgery possible, even in a chronic stage, if the patient is symptomatic. If the patient is asymptomatic, therapeutic abstention could be considered.

Left-sided omental torsion: CT appearance.

A 34-year-old male presented with exquisite left flank pain. Computed tomography showed a hyperdense vascular structure surrounded by whirling linear streaks situated in the greater omentum under the splenic flexure of the colon. Omental stranding extended caudally into the pelvis where part of the inflamed omentum entered a left inguinal hernia sac. Surgery revealed left-sided torsion of the greater omentum. Left-sided omental torsion is infrequent and pre-operative diagnosis is rarely established. The CT findings of an omental fatty mass with a whirling pattern is characteristic of omental torsion. Preoperative diagnosis is important because conservative management has been suggested.

[Malignant tumors of the ovaries: role of imaging].

Malignant ovarian tumors are developed in more than 95% in the epithelium surface of the ovary. In the mainly cystic forms, vegetations greater than 2cm, with an irregular surface, with a broad base on implantation, containing vessels on color Doppler are very suggestive of malignancy. Ultrasound is highly accurate in these forms. In most of the mixed forms on mainly solid forms, the irregular solid portions with degenerative changes containing tumoral vessels are very suggestive of malignancy. CT scan or MR imaging are usually more indicative of showing malignancy than ultrasound. In the multilocular forms, diagnosis of malignancy or benignity is often difficult. Extension to the pelvis, peritoneum and lymph nodes is easier to define on CT scan.

[Acute cholecystitis using computed tomography: usefulness of the trabeculation of the peri-cholecystic adipose tissue].

PURPOSE: To evaluate the significance of pericholecystic fat stranding on CT, and to compare it to other CT findings in patients with acute cholecystitis. MATERIALS AND METHODS: The CT examinations of 14 patients with proven acute cholecystitis were retrospectively reviewed and evaluated for the presence of findings consistent with this diagnosis. RESULTS: The most common CT finding was stranding of the pericholecystic fat (13 patients), followed by gallbladder distension (11 patients). Pericholecystic or perihepatic fluid was present in 6 patients in association with severe acute cholecystitis (6 patients) and biliary peritonitis (2 patients). CONCLUSION: Stranding of the pericholecystic fat was the most common CT findings in patients with acute cholecystitis, followed by gallbladder distension.

[Value of CT scan and MRI in primary tumors of the ovary].

Characterisation of an ovarian mass is of utmost importance in the preoperative evaluation of an ovarian neoplasm. It enables the surgeon to anticipate carcinoma of the ovary before the operation, so that adequate procedures are planned. Although, ultrasonography (US) remains the foremost imaging modality for screening patients with adnexal lesions, computed tomography (CT) recently has proved to be of value in the characterisation and management of tumors of the ovary. Magnetic resonance (MR) imaging has also been shown to have a high degree of diagnostic specificity for certain types of ovarian masses, such as dermoid cysts, and endometriomas. However, the potential of MR imaging to characterize tumors of the ovary has not yet been established. This study assesses the value of MR imaging and CT for the purpose of predicting the malignancy of ovarian lesions, and comparing findings of MR imaging with those of CT.

Penetrating carotid injuries--a wartime experience.

Thirty-nine patients with penetrating carotid injuries were treated between 1975 and 1987. All were war victims. On admission 27 (69%) had no neurologic deficit (group I), 8 (20.5%) had a mild neurologic deficit (group II), and 4 (10.5%) had a severe deficit (group III). Repair was undertaken in 38 of 39 (97.5%) patients, and carotid ligation was performed in 1 case (2.5%). Associated injuries were found in 25 (65%) patients. All patients survived. At the time of discharge all group I and II patients had a normal neurologic examination. One patient in group III recovered completely, whereas two had significant improvement. One patient remained unchanged. We conclude that repair should be attempted in all patients with carotid injuries who are seen early (less than 120 minutes) after the accident.

[Comparative study of MRI and x-ray computed tomography in the preoperative evaluation of rectal carcinoma].

Twenty-one patients with middle and low rectal carcinomas have been operated by abdominoperineal resection (APR) in 11 patients, and low anterior resection (LAR) with coloanal anastomosis in 7 and colorectal anastomosis in 3. The distance of the lower margin of the tumor to insertion of the levator ani on the rectal wall was correctly evaluated by CT in 15 of 21 cases (71%) and by MR in 14 of 21 (67%) while digital examination correctly assessed the distance in 17 of 21 (81%). CT and MR were unable to assess extension through the rectal wall. No significant discordance was observed between CT and MR in assessing extension to the perivesical fat, adjacent organs, pelvic side wall or lymphnodes. According to the TNM classification, MR correctly staged 76% (16 of 21) of patients while CT correctly staged 71% (15 of 21).

[Thoracic splenosis. Review of the literature apropos of a case].

Thoracic splenosis consists of autotransplantation of splenic tissue in the thorax following thoraco-abdominal trauma. The authors report a case of thoracic splenosis in a 35 year old woman who suffered a thoraco-abdominal gunshot wound 12 years previously. Sixteen cases of thoracic splenosis have been reported in the literature. Always asymptomatic, the thoracic lesions were discovered by chance on chest x-rays performed for various reasons 9 to 32 years after the initial trauma. Surgery was required in 13 patients in order to establish the diagnosis. In 2 cases Tc99 and Indium 111 isotope scans revealed the diagnosis, avoiding the need for surgery.

[X-ray computed tomographic aspects of dermoid cysts of the ovary].

155 patients with 210 ovarian tumours were examined pre-operatively by CT from December 1984 to February 1988. 27 patients had dermoid cysts, unilateral in 25 cases and bilateral in 2 cases. These cystic teratomas were benign in 26 patients. In one case, malignant transformation occurred. CT detected 29/29 tumours (100%). Presence of fat (26/29, 90%), calcification (20/29, 69%), Rokitansky protuberance (25/29, 86%), tufts of hair (20/29, 69%), or fat fluid level (4/29, 14%), allowed to make a definite diagnosis in 28/29 cases (96%). These findings and especially demonstration of fat, appeared to be specific for dermoid cysts in our series. The diagnosis of torsion of the cyst associated with torsion of the adnexa was made in 2 patients. No abdomino-pelvic extension occurred in 26/26 patients presenting with a benign dermoid cyst and CT correctly diagnosed the lymph node and hepatic spread in the single case of cancer.

[Contribution of MRI in the staging of cancer of the bladder. Apropos of 40 cases].

56 patients with bladder carcinoma were examined by magnetic resonance in the pre-operative staging. In 40 patients where total cystectomy with enterocystoplasty and pelvic node dissection were performed, a good correlation with surgical and pathologic findings was obtained. MR examination using T1 (TR 400 ms, TE 28 ms) and T2 (TR 1,200-1,600 ms, TE 40 80 120 ms) weighted images in different planes where performed after biopsy of the bladder tumor through endoscopy and within 1 or 2 weeks before surgery. Neoplasms were characterized by site, size and growth pattern. Extension through the deep muscle of the bladder wall was correctly identified in 95% with a sensitivity of 95% and a specificity of 95%. Extension through perivesical fat was assessed accurately in 85% with a sensitivity of 66% and a specificity of 100%. Accuracy in evaluating invasion of adjacent organs was 85%, sensitivity 44%, specificity 96%. Lymphadenopathy has been accurately assessed in 97.5% with a sensitivity of 83% and a specificity of 100%. MR correctly staged the tumor according to TNM classification in 24/40 (60%) patients, overestimated the extension in 3/40 (7.5%) and underestimated the extension in 13/40 (32.5%).
