Meningioma

A rare, mostly benign, primary tumor of the meninges (arachnoid cap cells), usually located in the supratentorial compartment, commonly appearing in the sixth and seventh decade of life, clinically silent in most cases or causing hyperostosis close to the tumor and resulting in focal bulging and localized pain in less than 10% of cases. Additional features may include headache, seizures, gradual personality changes (apathy and dementia), anosmia, impaired vision, exophthalmos, hearing loss, ataxia, dysmetria, hypotonia, nystagmus, and rarely spontaneous bleeding.

Osteochondroma

A cartilage capped bony outgrowth of a long bone. Osteochondroma arises on the external surface of bone containing a marrow cavity that is continuous with that of the underlying bone.

	Intraosseous venous malformations should be differentiated from other lesions, including intraosseous meningioma, fibrous dysplasia, osteochondroma, osteosarcoma, and ossifying fibroma.

	Intracranial osteochondroma is also a rare, benign tumor that can mimic meningioma when presenting in the dural convexity.

	Although the potential preoperative diagnoses based on computed tomography and magnetic resonance imaging included other intracranial tumors such as calcified meningioma, thallium-201 single-photon emission computed tomography effectively differentiated osteochondroma from those possibilities.

	A rare case of periosteal osteoblastoma located in the frontal cranial bone.
	Lin YC, Commins DL, Fedenko AN, Pinsky GS. Arch Pathol Lab Med. 2005;129(6):787-9.
	Although the differential diagnoses of periosteal lesions include parosteal and periosteal osteosarcoma, periosteal chondroma and chondrosarcoma, osteochondroma, osteoid osteoma, periostitis ossificans, and myositis ossificans, an important differential diagnosis both radiologically and pathologically of such a lesion in the cranium is meningioma.

	Since his first presentation, he has required surgery for multiple basal cell carcinomas, an osteochondroma of the rib, two meningiomas, a trigeminal schwannoma, and a pleomorphic liposarcoma, all of which arose within the radiation field.
