An incidental finding of an intracranial posterior fossa meningioma detected by bone scintigraphy is presented. Most of the published literature on the diagnosis of meningioma is on the use of CT and MRI. There is limited published literature on the detection of meningioma with bone scintigraphy.

Reconstruction of calvarium after tumor resection may present several technical difficulties. The authors reused the resected calvarial bone in four patients after submitting the bone to a lethal dose of gamma radiation. The authors conclude that resected, irradiated, tumorous bone can be reused for the reconstruction of its own defect. This provides a simple method of reconstruction. Partial bone resorption should be anticipated but further reconstruction, if needed, will be facilitated.

While meningiomas are common intradural tumors, such lesions only rarely arise outside of the meninges. All meningiomas, however, may slowly enlarge causing concern for malignancy. We report the appearance of an intraosseous meningioma in the patient with a history of breast carcinoma where the lesion progressively enlarged over a period of 5 yr to reach approximately three times the original size.

Meningioma is one of the neoplasms in which there may be extraosseous localization of bone-seeking radiopharmaceuticals. Tumor calcification, calvarial erosion, and the formation of reactive bone have been proposed as the cause of this abnormal tracer localization. We present a patient with a frontal meningioma that was evaluated using 99mTc-methylene-diphosphonate bone scintigraphy, head computed tomography, and skull radiography; the homogeneous density seen in the radiographic studies corresponded to the area of bone-seeking-agent localization shown in the scintigram. At autopsy, bony tissue and a few psammoma bodies were found in the meningioma, and apparently accounted for the bone-tracer localization. There was no calvarial erosion and no formation of reactive bone. If skull-radiographic studies show a homogeneous, radio-opaque lesion with no reactive changes in the adjacent skull, a meningioma showing a localization of a bone-seeking radiopharmaceutical may be predicted to have bone-tissue formation with or without psammoma bodies.
