Usefulness of 1H-MRS in the diagnosis of contrast enhancing cystic lesions: A case report

Abstract

The clinical and radiological features of brain abscesses can sometimes imitate those of necrotic tumors or metastasis. Whereas the approach and urgency of surgical intervention differs enormously, further diagnostic features are necessary in order to establish the correct preoperative diagnosis.

We report on two patients who presented with septated ring-enhancing lesions in the right parieto-temporal hemisphere with perifocal edema and discuss the role of 1H-magnetic resonance spectroscopy (MRS) in the diagnosis of contrast enhancing cystic lesions.
