Computed tomography of oleothorax.

Oleothorax as therapy for pulmonary tuberculosis was discontinued some 35 years ago. An oleothorax may expand and cause respiratory distress. Additional complications include bronchopleural fistula and cutaneous fistula. Computed tomography has not previously been used to evaluate oleothorax. This case report describes the use of computed tomography in a patient with a symptomatic oleothorax.

Mediastinal pancreatic pseudocyst.

We have described a case of extension into the mediastinum by a pancreatic pseudocyst. This rare phenomenon should be included in the differential diagnosis of mediastinal mass lesions. We advocate the use of CT in evaluating a mediastinal mass to determine its solid or cystic nature, size, extent, and relationship to adjacent structures.
