Periportal tuberculous adenitis: a rare cause of obstructive jaundice.

A patient with a clinical history of pulmonary tuberculosis presented with obstructive jaundice. Compression of the extrahepatic bile ducts was caused by calcified lymph nodes secondary to tuberculous adenitis of the porta hepatis. The role of radiologic methods in the diagnosis and management of this unusual complication is discussed.

Computed tomography as an angiographic aid in evaluation of intraabdominal hemorrhage.

The role of computed tomography in the evaluation of patients with intraabdominal hemorrhage in the absence of trauma history has received little attention. Representative cases are presented demonstrating how preangiographic, postangiographic, and combined computed tomography-angiography can aid in the diagnosis and localization of obscure causes of intraabdominal and gastrointestinal bleeding.

Pancreatic and peripancreatic vessels: embolization for control of bleeding in pancreatitis.

Bleeding associated with pancreatitis has a high mortality rate. Angiographic demonstration of uncontrollable bleeding or large pseudoaneurysms is an indication for emergency surgery. We have encountered a group of patients with obvious clinical gastrointestinal hemorrhage out of proportion to angiographic findings. Vessel abnormalities included areas of encasement, small pseudoaneurysms, and occasional extravasation without a clearly defined source. With the high risk of mortality in such patients, embolization is a viable method of therapy. Three patients are described who had different angiographic presentations and in whom hemorrhage was safely controlled with embolic therapy using nonpermanent occlusive materials.

Routine preoperative biliary drainage: effect on management of obstructive jaundice.

The routine application of preoperative percutaneous transhepatic biliary drainage (PTBD) to patients who have obstructive jaundice has a significant effect on overall morbidity, mortality, and patient survival by allowing selective application of the most appropriate therapeutic modality. Surgical patients who undergo PTBD were compared with those for whom PTBD was not available. The surgical complication rate was 44% for those who did not undergo PTBD and 15% for those who did. The surgical procedure-related mortality rate was 30% for those who did not undergo PTBD and 12% for those who did. These differentials may have been due either to a beneficial effect of presurgical decompression or to the fact that only more favorable candidates were selected for operative internal bypass. There was an overall increase in length of survival following the application of PTBD, especially in those patients who were surgical candidates.

Thoracic biopsy: CT guidance of thin-needle aspiration.

CT-guided percutaneous thin-needle aspiration biopsy of 23 mediastinal and 27 other thoracic masses was performed in 40 patients over a 2-year period. Although biplane fluoroscopy is considered the optimal guidance mechanism for thoracic biopsy, CT was required in this group of patients to ensure accurate needle placement within the lesions or within the most appropriate subsegment of necrotic lesions. A specific diagnosis was obtained in 34 cases, an overall diagnostic accuracy of 85%. Although CT guidance allowed an extrapleural needle trajectory in 23 patients, five of the remaining 17 patients sustained a pneumothorax for which two required tube thoracotomy.

Sonography of systemic lupus nephritis.

Renal sonography was compared with commonly obtained laboratory and pathologic data in 31 patients with systemic lupus erythematosus. Sonography was 95% sensitive in the detection of lupus nephritis, with the major abnormalities being abnormal renal size and cortical echogenicity. Sonography was useful in locating the kidneys for biopsy and in excluding hydronephrosis. However, in the overall evaluation of patients with uncomplicated lupus nephritis, sonography added little information not readily available from laboratory data.

Angiographic demonstration of gastrointestinal neurofibromas in von Recklinghausen's disease.

Two cases of intestinal neurofibromas which were demonstrated during mesenteric arteriography are described. In 1 patient, tumors located in the jejunum and distal ileum were the apparent source of gastrointestinal bleeding. In another case, a neurofibroma of the proximal jejunum was an incidental finding during evaluation for severe pancreatitis and bleeding from esophageal varices.

Computed tomographic demonstration of hemobilia.

A patient with hemobilia presumably due to a small hemangioma in the liver is presented. The condition was diagnosed by computed tomography (CT) done immediately following hepatic arteriography and confirmed by hem-positive duodenal aspirates on two occasions.

CT evaluation of thickened esophageal walls.

A study of 200 consecutive chest computed tomographic (CT) examinations revealed thickened esophageal walls (over 3 mm) in 35%. While this is the earliest finding of carcinoma of the esophagus on CT, only half of the cases of thickened walls were due to esophageal carcinoma. Other mediastinal malignancies as well as benign inflammatory, vascular, and fibrotic conditions such as reflux and monilial esophagitis, esophageal varices, and postirradiation scarring were found to cause thickened esophageal walls. Distension with air and intravenous enhancement aid in the optimal evaluation of the esophagus by CT. The thickened esophageal wall is always abnormal, but it is nonspecific, seen in both malignant and nonmalignant conditions.

Computerized tomographic evaluation of early idiopathic midline granuloma.

Idiopathic midline granuloma (IMG) is a rare, slowly progressive inflammatory process producing localized destruction of the nasal mucosa, septum, paranasal sinuses, and palate, often associated with erosion through central facial tissue and bone. We review some of the salient features of IMG and present the first reported CT demonstration of this disease.

Air esophagram after laryngectomy.

Air in the esophagus is frequently visible on chest radiographs of patients who have undergone laryngectomy (15/30; 50%). It is more frequently seen in those who successfully use esophageal speech (11/18; 61%) than in those who do not (4/12; 33%). The esophagus may be dilated, totally air filled, and contain an air-fluid level. A discussion of the physiology of esophageal speech and a differential diagnosis of esophageal air are presented. An air esophagram in patients using esophageal speech after laryngectomy in the absence of symptoms of an obstructing lesion should not be considered abnormal.
