Case Reports Comparative StudyDense dermoids in craniocervical region.
Computed tomography of dermoids and epidermoids usually demonstrates areas of variable hypodensity, located most frequently in the sellar region and in the cerebellopontine angle. This report presents two cases of hyperdense dermoids of the craniocervical region which are compared with six other cases described in the literature.

Case ReportsComputed tomography of the subperitoneal space: demonstration of direct spread of intraabdominal disease.
The direct spread of intraabdominal disease via peritoneal folds is clearly demonstrated with computed tomography (CT). This extensive network of peritoneal folds can be conceptualized as the subperitoneal space. These subperitoneal communications within the abdomen are described and demonstrated by CT scans and a schematic drawing. Direct spread of disease within and between abdominal compartments is illustrated with selected clinical cases stressing the CT imaging method.

A clinical computed tomographic (CT) study of six patients, two with tension and four with benign postoperative subdural pneumocephalus, was done coupled with a data analysis of the literature. The mass effect of a tension subdural pneumatoma was demonstrable as shift in the midline structures when the air was unilateral, whereas an asymptomatic pneumocephalus showed no actual mass effect. ⋯ Of 21 reported cases of postsurgical tension pneumocephalus, 18 (86%) had the pneumatoma in the subdural space. The predisposing neurosurgical conditions to tension pneumatoma included: (a) a preexisting open cerebrospinal fluid drainage device; (b) surgery on the posterior fossa in the sitting position; and (c) chronic subdural hematoma.

The computed tomographic (CT) findings of a classic case of Page kidney (hypertension resulting from compression of the renal parenchyma by a subcapsular hematoma) is presented. An excretory urogram and renal arteriogram performed prior to the CT study resulted in nonspecific findings. The CT findings of a well circumscribed, elliptically shaped, low density, subcapsular hematoma producing parenchymal compression was correlated with the onset of hypertension following remote trauma, permitting the CT diagnosis of Page kidney.
