RT Journal Article SR Electronic T1 Inflammatory Pseudotumor of the Trigeminal Nerve: A Neoplastic Mimic You Do Not Want to Miss JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 1941 OP 1943 DO 10.3174/ajnr.A1641 VO 30 IS 10 A1 Seol, J.G. A1 Loevner, L.A. A1 O'Malley, B.W. A1 Grady, M.S. YR 2009 UL http://www.ajnr.org/content/30/10/1941.abstract AB SUMMARY: Inflammatory pseudotumor is a rare non-neoplastic mass that may clinically and radiologically mimic a spectrum of benign and malignant neoplasms. It is uncommon in the head and neck and particularly rare at the skull base. We present a case of pseudotumor originating from the trigeminal nerve in a patient who presented with headache and facial numbness. A high index of suspicion is necessary to diagnose this benign but locally aggressive entity.
