Cellular whorls in brain tumors other than meningiomas.
Cellular whorls with or without secondary calcification are generally regarded as reliable diagnostic criteria in the differential diagnosis of meningiomas. They may however occasionally occur in other primary and metastatic brain tumors. Five cases (metastatic laryngeal carcinoma, metastatic mammary carcinoma, metastatic melanoma, medulloblastoma, and giant cell glioblastoma) are presented to illustrate this phenomenon occurring in non-meningothelial brain tumors.
