Magnetic resonance imaging of non-specific inflammatory granulation involving the skull base--two case reports.
A 55-year-old male presented with a 20-day history of nuchal pain and hypoglossal nerve paresis on the right. T2-weighted magnetic resonance (MR) imaging showed an isointense lesion with a small hypointense part in the hypoglossal canal and caudal clivus. A 66-year-old female presented with a long-standing history of left orbital pain. T2-weighted MR imaging showed a hypointense lesion occupying the orbital apex which on recurrence became isointense. The histological diagnosis of both lesions was non-specific inflammatory granulation. The T2-weighted MR imaging appearance of this entity is variable, and can change within the clinical course of the same lesion.
