CT demonstration of resolution of hepatic lesions in HELLP syndrome: a case report.

This article describes the CT appearance of the liver in a patient with HELLP Syndrome in the acute and resolving phases of the disease. In the acute phase, computed tomography showed multiple confluent hypodensities in the left and right hepatic lobes, ascites, and subcutaneous abnormalities.

CT findings of hypervascular malignant peritoneal mesothelioma.

A case of peritoneal mesothelioma is presented in which CT demonstrated abnormal regions of increased vascularity in the omentum corresponding to hypervascular omental lesions shown by angiography. This CT appearance has not been described in prior reports of CT in peritoneal mesothelioma.

Sagittal orientation of the anterior minor fissure: radiography and CT.

Chest radiographs of 12 patients revealed an oblique, predominantly cephalocaudal linear opacity in the anterior inferomedial aspect of the right lung. Correlation with high-resolution computed tomography in two patients indicated that this opacity represented a sagittal orientation of the anterior minor fissure, with resultant inferomedial curving of the right upper lobe of the lung along the right border of the heart. The sagittal anterior minor fissure may extend inferiorly to the right hemidiaphragm and merge superiorly with the horizontal minor fissure. Autopsy findings in one case showed that this anatomic variant may explain potentially confusing radiographic manifestations of disease in the anterior segment of the right upper lobe of the lung and in the medial segment of the right middle lobe of the lung.

Traumatic lumbosacral nerve root avulsion: evaluation by MR imaging.

Magnetic resonance (MR) imaging of traumatic lumbosacral nerve root avulsion and pseudomeningocele formation at multiple nerve root levels is presented. We report a case of this rare clinicopathologic entity identified by MR imaging in conjunction with more traditional lumbar myelography.

Urinary obstruction in azotemic patients: detection by sonography.

Renal sonography is frequently requested in patients with an elevated or rising creatinine, often with the instruction to "rule out obstruction." A prospective study of patients undergoing renal sonography for newly discovered azotemia (creatinine greater than 1.8 mg/dl) or worsening renal failure was undertaken to evaluate the clinical utility of the sonographic examination. Patients with known obstructive uropathy, renal calculi, renal mass, or hematuria were excluded. In 189 patients, 17 (9%) had hydronephrosis: 11 unilateral (one with a solitary kidney) and six bilateral. Obstructive causes were subsequently established in the solitary kidney and in four patients with bilateral dilatation. These five patients (2.6%) with clinically significant hydronephrosis were shown subsequently to have a clinical history that strongly suggested the presence of urinary tract obstruction. Our data suggest that, in patients without a clinical history that suggests obstruction (such as calculi, bladder outlet obstruction, or pelvic mass), the likelihood of finding bilateral hydronephrosis by sonography is small.
