BACKGROUND AND PURPOSE:We present neuroradiologic findings in 17 patients with posterior fossa malformations, hemangiomas, arterial anomalies, cardiac defects, eye abnormalities, and sternal or ventral defects (PHACES) association and identify those at highest risk of central nervous system (CNS) structural, cerebrovascular, and neurodevelopmental abnormalities.
We report the fine-needle aspiration biopsy findings of sclerosing hemangioma of lung occurring in a 40-yr-old Chinese woman. Cytologically, there were hyalinized stromal tissue fragments admixed with clusters of nondescript mononuclear tumor cells. Scattered foamy macrophages and red blood cells were also noted in the background. Focal papillary and acinar configurations were seen. However, some of the epithelial cells show nuclear pleomorphism with nuclear hyperchromasia, prominent nucleoli, and occasional intranuclear inclusions. Mitotic activity was virtually absent. The cytologic atypia present may result in misdiagnosis of well-differentiated pulmonary adenocarcinoma, especially bronchioloalveolar carcinoma. Recognition of the subtle cytologic differences, together with cell block examination, immunocytochemistry, and proper clinicoradiologic correlation, is crucial for an accurate preoperative diagnosis.
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.
