title: In vivo proton magnetic resonance spectroscopy in a known case of intracranial hydatid cyst.
abstract: We are presenting magnetic resonance spectroscopy (MRS) findings of a known case of hydatid cyst operated twice in the past. A 22-years-old male patient had presented with recurrent symptoms of generalized seizures and raised intracranial tension. MRI with MRS of the lesion was performed that showed a recurrent loculated cystic lesion in right parieto-occipital lobe. MRS through the lesion was performed using repetition time (TR) of 1500 ms and time to echo (TE) of 135 ms using 2 x 2 x 2 cm voxel, from the margin of the lesion. MRS showed mildly elevated choline (Cho), depressed creatine (Cr) and N-acetyl aspartate (NAA), a large peak of lactate, pyruvate and acetate peaks.
