We report a case of epidermoid, in which proton MR spectroscopy (MRS) provided additional informa-tion to MRI. The tumor revealed high signal intensity on T 2-weighted images (WI) and low signal intensity on T 1 WI. No enhancement was observed. Proton MRS was acquired with the Proton Regional Imaging of Metabolites (PRIME) method (TR/TE/measure-ments =2,000 ms/136,272 ms/128 times). Proton MRS revealed lactate (Lac) peak at 1.33 ppm as negative peak at TE 136 ms and positive peak at TE 272 ms.
