Vascular changes in leprosy and its role in the pathogenesis of leprous neuritis.

The arteriographic pattern of left hand vessels was studied in 20 patients in leprosy by percutaneous brachial arteriography. Arteriographic abnormalities noted consisted of occlusion, narrowing, tortuosity, dilatation, irregularity and incomplete filling of the lumen by contrast medium. Such abnormal findings were seen in all the arteriograms studied and more than one vessel involvement was noted in over 50 percent cases. This study clearly demonstrated that arterial involvement in leprosy was frequent. No correlation was found between motor weakness and vascular abnormalities. There was no difference in arterial lesions between the patients with and without trophic changes. There was also no correlation between the severity of vascular changes and decline in motor nerve conduction. Degree of histopathological abnormalities in the sural nerve biopsy from these patients showed no features of micro angiopathic neuropathy. It is concluded that the observed vascular abnormalities do not contribute significantly in the genesis of neurological deficit in leprosy.

Ureteric diverticula: ureterodiverticular reflux and yo-yo effect. A television study with spot filming.

Two cases of ureteric diverticulum are presented. Repeated infective episodes were the main presenting features in one, whereas intermittent attacks of colicky pain brought the other patient in for clinical assessment. Fluoroscopic evaluation of the latter patient demonstrated free ureterodiverticular reflux and yo-yo phenomenon. Following diverticulectomy the pain completely disappeared.

Amebic liver abscess with hemobilia.

A patient with hemobilia complicating an amebic liver abscess is described. The diagnosis was based on selective arteriography. The hemobilia did not stop with antiamebic treatment or ligation of the right hepatic artery. Successful results followed right hemihepatectomy.

Hydatid cyst causing spinal compression.

This report deals with two cases of spinal cord compression, one secondary to hydatid disease of C4 vertebra and the other due to a posterior mediastinal hydatid with an intraspinal component. After a brief review of the pertinent literature and pathogenesis of the disease, the distinguishing radiological features have been brought out.

Ultrasound-guided percutaneous nephrostomy in non-dilated pelvicaliceal system.

Percutaneous placement of nephrostomy catheters in patients with non-dilated pelvicaliceal systems remains problematic. We successfully performed ultrasound-guided percutaneous nephrostomies in 5 such patients after intravenous administration of a diuretic agent. Diuresis resulted in transient dilatation of the calyces, facilitating the procedures, which were performed under real-time sonographic guidance using the Seldinger technique. No complications were encountered.

Sonographically guided fine-needle aspiration biopsy of lytic lesions of the spine: technique and indications.

PURPOSE: We report the use of sonography to guide fine-needle aspiration biopsies (FNABs) of lytic lesions of the spine. METHODS: Twenty-nine patients with lytic vertebral lesions with or without associated extraosseous soft-tissue extension underwent sonographically guided FNAB. Twelve cervical, 7 thoracic, 7 lumbar, and 3 sacral lesions were biopsied. Tissue samples were taken from either the bony lesion through a break in the cortex (n = 9) or the associated soft-tissue extension (n = 20). RESULTS: Adequate diagnostic material obtained in 27 cases (93%) revealed an inflammatory (n = 13) or malignant process (n = 14). Of the 2 patients with inconclusive FNAB findings, 1 patient was lost to follow-up, and the other underwent surgery, which revealed tuberculosis. No complications of FNAB were encountered. CONCLUSIONS: We conclude that sonography is a safe and effective guidance modality for FNAB of lytic lesions of the spine, especially for lesions in the cervical region. In the thoracic, lumbar, and sacral regions, however, the role of sonographically guided FNAB is limited to lesions affecting the posterior elements.

MRI findings of retrobulbar myxoma-- a case report.

Myxomas are benign soft tissue neoplasms, which usually involve the heart, skin and subcutaneous tissues, and rarely the ocular adnexa. We present a rare case of orbital myxoma with magnetic resonance imaging (MRI) findings and a review of the literature.

CT features of acute phlegmonous gastritis.

One case of phlegmonous gastritis is presented. Radiological diagnosis of this condition is difficult. In the setting of a clinical suspicion of this condition, computed tomography (CT) is the imaging modality of choice.

Imaging features of esophageal leiomyomatosis: a case report.

Leiomyomas are the most common benign tumors of the esophagus. However, esophageal leiomyomatosis is a rare pathologic entity that has received little attention in the radiologic literature. We present a case of esophageal leiomyomatosis with imaging features on barium swallow and computed tomography (CT).

Two-phase dynamic contrast-enhanced computed tomography with water-filling method for staging of gastric carcinoma.

The objective of the study was to evaluate the usefulness of two-phase incremental contrast-enhanced computed tomography (CT) with water-filling method in the preoperative assessment of stomach carcinoma. Dynamic CT was done in 20 patients with biopsy-proven gastric cancers and the findings were compared with surgery. A 150-ml ionic contrast medium was administered intravenously at a flow rate of 3.5 ml/s. CT scanning was done at 45 s (early phase) and 3 min (equilibrium phase) after the start of intravenous injection. Primary tumors were detected in all the cases. The overall accuracies of dynamic CT in determining depth of tumor invasion, pancreatic invasion, adjacent liver infiltration, and lymph node metastasis were 85% (17/20), 90% (18/20), 85% (17/20), and 69% (13/19), respectively. The early phase of dynamic CT is highly accurate in determining the depth of tumor invasion of advanced gastric cancers but has low sensitivity in the detection of nodal metastasis. The delayed phase scans do not add any additional information and hence, should not be routinely used for staging.

Hepatic-pericardio-phrenic collateral (natural shunt) in a patient with Budd-Chiari syndrome.

Hepatic venous outflow tract obstruction, Budd-Chiari syndrome (BCS), leads to portal hypertension and to the development of collaterals that bypass the obstruction. Described here is a BCS patient with an unusually large transdiaphragmatic collateral between the left hepatic and left innominate veins, which decompressed the oesophageal varices. This has not been reported earlier in the literature.

T-tube access for endoscopic sphincterotomy: a variant of combined percutaneous and endoscopic approach.

Selective deep cannulation of the common bile duct (CBD), which is essential for successful endoscopic sphincterotomy, may not be possible in all patients. Three patients with retained CBD stones with T-tube in situ in whom selective deep cannulation failed, underwent successful sphincterotomy using a combined percutaneous and endoscopic procedure through the T-tube. CBD stones were then extracted with a Dormia basket. In situ T-tube can provide percutaneous access for combined approach in patients with retained CBD stones in whom endoscopic cannulation is not successful.

Pergolide-induced retroperitoneal fibrosis.

Retroperitoneal fibrosis is a rare complication of pergolide therapy. This complication can be easily missed, so it is essential to have a high index of suspicion. We describe a case of well controlled Parkinson's disease who presented with shortness of breath and oedema.
