A cluster of irregular ring-enhancing lesions in the right cerebellar hemisphere demonstrate a thin complete rim of enhancement, with central T2 hypointensity and diffusion restriction. Moderate expansion of the right cerebral hemisphere and compresses the fourth ventricle. The lateral and third ventricles are dilated and there is transependymal oedema.
No abnormal leptomeningeal or pachymeningeal enhancement. No ventricular wall enhancement or intraventricular diffusion restriction. No supratentorial ring-enhancing lesions or abnormal diffusion restriction.
- features favour multiple abscesses and low T2 suggests tuberculosis
- obstructive hydrocephalus with transependymal oedema
