Fig. 4

A 31-years-old female with left CPA space mass lesion. The mass is seen iso-intense on T1WI (a), T2 hyperintense and extending into the IAC without widening (b, c), showing homogenous post-contrast enhancement, with a dural tail on T1WI+C (d), displacing the 8th cranial nerve on CISS (e), hyperintense on DWI (f), low ADC value 0.8 × 10−3 mm2 (g), expressing alanine peak on MRS (h). The T2 hyperintense signal was not usual for meningioma still broad-based appearance and dural base suggested meningioma, with additional support by spectroscopy and diffusion data. Surgical resection revealed meningioma
