Calcified dural based meningioma, mimicker of metastasis on skeletal scintigraphy.

Meningiomas are meningeal based slow growing tumours most of which are benign in nature. Calcification in these tumours leads to Technetium labeled Methylene Diphosphonate (Tc99m-MDP) uptake on skeletal scintigraphy. Hybrid SPECT-CT bone scanning offers anatomic details and differentiates between benign entity and metastasis. We present the case of a 56-years-old female with right breast carcinoma. Bone scintigraphy, acquired as a part of baseline staging work up, showed focal skull uptake mimicking skeletal metastasis. SPECT-CT scan demonstrated characteristic anatomic features of calcified meningioma in right parietal region.
