Orbital wall tumor and intradiploic meningioma are rare tumors. Magnetic resonance imaging and nuclear medicine findings in the cases of orbital intradiploic meningioma have rarely been reported. A 46-year-old man presented with gradually appearing exophthalmos. MR and nuclear medicine findings revealed intradiploic tumor on the lateral orbital wall. The patient underwent total tumor resection and final pathological diagnosis was benign meningioma. This case highlights the importance of pathological conformation before performing extensive surgery. Thallium single-photon emission computed tomography is a valuable technique for distinguishing intradiploic benign meningioma from other malignant tumors.

Keywords: Intradiploic meningioma, Orbita, SPECT.

Orbital wall tumor is rare, but a variety of primary and secondary tumors involving the orbital wall have been reported [1,2]. Intradiploic meningioma is another rare tumor [3,4]. We treated a rare case of intradiploic meningioma in the lateral orbital wall.
