RESUMO
The clinical and radiological features of parotid-gland sarcoidosis in 22 patients are presented. This occurred in association with systemic disease as painless, diffuse and nonnodular parotid swelling. Conventional sialography usually demonstrated normal proximal ducts, a few fragile distal ducts and non-specific parenchymal nodules. Computed tomography, with or without simultaneous sialography, defined and characterised such nodules and demonstrated normal periparotid anatomy. Sialography contributes little additional information to thorough clinical examination in non-nodular or multinodular glands. However, solitary nodules appear to be better investigated by sialography, CT and CT-guided aspiration, thereby allowing diagnosis and direct medical therapy and avoiding surgery. Ultrasonography and nuclear scintigraphy were of little value in this study.

Chronic subdural hematoma was identified radiographically and verified surgically in two patients with brain tumor, one meningioma, and one glioblastoma multiforme. Over a period of days or weeks, both patients developed dramatic clinical findings probably related to the mass effect from the subdural hematoma in addition to the preexisting tumor. Early awareness of this complication in patients with brain tumor may lead to successful surgical treatment.

The CT features of a case of adult ileocolic intussusception and of experimentally induced ileocolic, cecocolic, and colocolic intussusceptions are presented. Both the clinical and experimental cases demonstrated (1) "target" masses with enveloped, eccentrically located areas of low density and (2) interspersed low- and high-density stripes within the intussusception producing a "layered" or "stratified" pattern. This layered pattern of abdominal masses may be characteristic of intussusceptions regardless of location.
