Scimitar syndrome.

Scimitar syndrome, a rare anomaly of partial pulmonary venous drainage into the hepatic portion of the inferior vena cava, detected in a ten-day-old neonate who presented clinically with respiratory distress and diagnosed on ultrasound of the thorax is being reported here.

Adult duodenal web.

An 18-year-old male presented with persistent vomiting and epigastric fullness of 8 months' duration. Barium examination revealed an abrupt cutoff at the third part of the duodenum. Duodenotomy revealed a web at the third part of the duodenum. Following web excision, the patient experienced marked symptomatic relief and remains well 6 months after surgery.

Primary pleomorphic sarcoma of the liver.

A 35-year-old woman presented with abdominal distension and a palpable liver mass. Ultrasonography and computed tomography revealed a large well-delineated liver mass with bilobar involvement. Based on autopsy and immunohistochemical findings, a final diagnosis of primary pleomorphic liver sarcoma with myogenic differentiation was established.

Retroperitoneal perforation in ulcerative colitis with mediastinal and subcutaneous emphysema.

Retroperitoneal colonic perforation in patients with ulcerative colitis is rare. We report such a case in a patient with severe ulcerative colitis without toxic dilatation in whom mediastinal and subcutaneous emphysema also developed. Unlike previously reported cases, our patient was treated conservatively with intravenous fluids, parenteral nutrition, intravenous hydrocortisone, and antibiotics. After 2 weeks, the mediastinal and subcutaneous emphysema and the retroperitoneal air completely disappeared.

Control of tubercular haemoptysis by bronchial artery embolization.

Thirty-seven patients presenting with massive or recurrent haemoptysis secondary to tuberculous aetiology were subjected to bronchial artery angiography. Of these, failure, to catheterize the bleeding vessel occurred in two patients while embolization was withheld in two patients due to the presence of anterior spinal artery arising from a common intercosto-bronchial trunk. Immediate arrest of bleeding was performed in the remaining 33 patients by selective embolization of the abnormal bronchial arteries with a resorbable material (Gelfoam). Regular follow up for a duration of 6 months after the procedure revealed relapse of haemoptysis in four patients; three were treated by re-embolization of the abnormal bleeding vessels while one patient died due to aspiration immediately on admission. No recurrence of bleeding was seen in the remaining 29 patients. It is concluded that bronchial artery embolization is an effective treatment for immediate control of life-threatening haemoptysis.

Sonographic evaluation of biliary ascariasis.

In a prospective 6-month study, sonographic diagnosis of biliary ascariasis was made in 14 patients; in nine patients, the diagnosis was confirmed by endoscopic retrograde cholangiopancreatography and bile analysis, while in five patients, confirmation was obtained by proven intestinal infestation. No false-positive or false-negative cases were encountered. Ascariasis of the biliary tract was seen on ultrasound as echogenic, non-shadowing images, either as single or multiple strips, with visualization of the digestive tract of the worm as an anechoic inner tube, or as amorphous fragments. Follow-up sonograms helped in detection of worm expulsion following medical therapy in five patients, while endoscopic extraction of the worm was performed in four patients. In three patients, disappearance of the worm from the biliary tract was noted following a therapeutic sphincterotomy, and two patients detected to have a worm within the gall-bladder were operated on. In all patients, serial sonograms revealed disappearance of the worm, and the regression of biliary tract dilatation.
