MRS findings in cerebral coenurosis due to Taenia multiceps.

Cerebral coenurosis due to Taenia multiceps is a rare infection with no case reports from India. A 55-year-old male patient had presented with progressive symptoms of hemiparesis of 1-year duration. Magnetic resonance imaging (MRI) with magnetic resonance spectroscopy (MRS) of the lesion was performed that showed a septated cystic lesion in left parieto-occipital lobe. Multivoxel MRS through the lesion was performed using repetition time of 1500 ms and time to echo of 144 ms at 3T MRI. MRS showed mildly elevated choline (Cho), depressed creatine (Cr), and N-acetyl aspartate (NAA), a large peak of lactate, pyruvate, and acetate peaks. To best of our knowledge, there has been no reported case of in vivo proton MRS finding ever reported. We present MRS findings in this operatively proven case of T. multiceps cyst of the brain.
