Streaming hypointensity in hemorrhagic glioblastoma multiforme. An illustrative case.

The computed tomography, the magnetic resonance and the angiographic features of a patient with the unusual findings of multicentric intraparenchymal, subependymal and intraventricular hemorrhage in association with glioblastoma multiforme are presented. The utility of MR in demonstrating an irregular, streaming pattern of hypointensity within the lesion (and thereby suggesting an underlying neoplasm) is briefly discussed.

Spinal cord compression in type I Gaucher disease.

Three patients with epidural compression of the spinal cord, a rare but serious complication of type I Gaucher disease, are described. In two cases the compression occurred at the lower thoracic region due to collapse of T-11 and T-12, respectively. In the third case, an epidural mass developed at the dorsal aspect of the cord at T-2, and T-2 and T-3 showed diffuse infiltration without collapse. In two cases the diagnosis was made with magnetic resonance (MR) imaging. In these cases MR imaging proved to be a safe, accurate method for demonstrating the nature and extent of disease within the spinal canal.

Preoperative chest radiography: value as a baseline examination for comparison.

An important use of the preoperative chest radiograph is as a baseline for comparison when complications occur after surgery. Many authors have commented on the value of preoperative chest radiography as a screening examination, but no statistics have been presented regarding its impact on postoperative management. In 369 consecutive general surgical patients, the need for a baseline chest radiograph was evaluated. In 65 patients undergoing chest radiography postoperatively, a preoperative baseline was essential in making an accurate interpretation in 33 (51%). The value of preoperative chest radiography proved to be twofold. Some minimal abnormalities on postoperative radiographs were demonstrated to be clearly new, necessitating treatment or further evaluation. Second, significant abnormalities detected on postoperative radiographs that may have otherwise been subjected to expensive evaluation were often shown to have been present preoperatively. In approximately 9% of patients the preoperative chest radiograph had a significant impact on postoperative management.
