Cerebral mucormycosis: proton MR spectroscopy and MR imaging

Proton magnetic resonance spectroscopy (MRS) was integrated with magnetic r esonance imaging (MRI) in the evaluation of a case of cerebral mucormycosis . MRS showed markedly elevated lactate, depleted N-acetyl aspartate and met abolite resonances attributable to succinate and acetate. The spectroscopy profile is essentially similar to that of bacterial abscess but without the commonly seen resonances of the amino acids valine, leucine and isoleucine . Our extensive literature review did not yield any reports of MRS findings on cerebral mucormycosis. MRS prospectively limited the differential diagn oses given the otherwise nonspecific and complex MR imaging findings in our immunosuppressed patient. (C) 2000 Elsevier Science Inc.
