A case of metastatic pheochromocytoma is reported in which the diagnosis was determined on the basis of a painless scalp mass. Subsequent to biopsy and histological diagnosis, further investigations revealed a large skull lesion with intracranial extension, an adrenal mass, and various catecholamine abnormalities. The radiological characteristics and operative findings of this case are described, and the literature regarding pheochromocytoma with intracranial metastatic extension is reviewed.

Computed tomography and MRI on two patients with known HIV infection and bilateral parotid lymphoepithelial cysts are presented. Both patients also had bilateral multiple submandibular gland cysts and no evidence of obstructive glandular disease, autoimmune disease, or other organ system cysts. These cases of presumed submandibular gland lymphoepithelial cysts are rare in the literature. They are presented in the hope that other radiologists will be stimulated to document the occurrence of this entity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
