Abstract

Deep sylvian meningioma is a rare form of meningiomas. So far, only 4 cases including the present one have been reported in South Korea. A 43-year-old man without any previous medical history presented to our hospital with seizure. There was a rim enhancing mass in the right deep sylvian fissure without dural attachment on magnetic resonance images. Surgical resection of the mass revealed the lesion to be a meningioma in this patient.

Figure

• 

  Fig. 1 The initial CT (a) study revealed a 15×16×16 mm rim enhancing mass located in the distal portion of right sylvian fissure with minimal calicifications. On MRI study, this lesion was found to have iso-signal intensity in T1 (b) and T2 (c) weighted images with surrounding adjacent edema. In T1 contrast phase (d, e), the mass showed ring like enhancement.
