Operative strategies in the management of mediastinal pancreatic pseudocyst.

Thirty-four cases of mediastinal pancreatic pseudocyst have been previously reported. Among the 32 previous reports with operative or autopsy analysis, communication has been identified in 30. Even when this communication has been quite small between the mediastinal fluid collection and the pancreas, the recommended operative strategy has been enteric drainage directly to this communicating tract.

MR imaging of mediastinal pseudocyst.

Magnetic resonance imaging of a mediastinal pseudocyst clearly demonstrated the entirely intrathoracic location of the pseudocyst.

Renal transplant dysfunction: MR evaluation.

The results of 45 MR examinations were prospectively compared with the clinical course and biopsy results in 38 renal transplant patients to determine the role of MR in evaluating allograft dysfunction. Twenty-six patients underwent allograft biopsy. In eight patients in whom the biopsy was performed more than 48 hr after MR examination and in 19 patients who did not have a biopsy, the subsequent clinical course was sufficiently diagnostic to determine the specific cause of the transplant dysfunction.

Pseudocyst following splenectomy: impact of CT and ultrasound on its diagnosis and management.

Three cases of pseudocysts occurring after splenectomy are presented. Sonography and computed tomography were helpful in diagnosing the pseudocysts as well as providing guidance for subsequent drainage. Demonstration of a cystic mass adjacent to the tail of the pancreas following splenectomy suggests the diagnosis of postsplenectomy pseudocyst and has important implications for clinical management.

Potential placenta previa: definition, frequency, and significance.

Sixty-three (5%) of 1239 women studied by sonography during the second trimester of their pregnancies had a diagnosis of placenta previa. Follow-up was available for 51 of the 63 patients; in three of these, the original diagnosis was complete placenta previa, and in the other 48, the first diagnosis was partial or marginal placenta previa. At term, placenta previa was seen in only four patients for an overall frequency of 0.
