Intracranial Mass Lesion Caused by Inflammatory Pseudotumor: A Case Report and Discussion

Inflammatory pseudo tumors are uncommon lesions that may, on occasion, occupy the intracranial space. Their management is unstandardized. We present a case of skull-based inflammatory pseudotumor in a 14-year-old boy who presented with multiple cranial nerve palsies mimicking Gradenigo syndrome. This illustrative case and a review of the literature is presented to highlight noteworthy features of this rare condition. These include that inflammatory pseudotumor may be multifocal and biopsy of a more accessible, smaller lesion may prove diagnostic.
