Cerebellar

abscess secondary to occipital dermoid cyst with dermal sinus. Pre-contrast T1W coronal images – high signal in subarachnoid space in posterior fossa consistent with leakage of fatty content of dermoid.

Cerebellar

abscess secondary to occipital dermoid cyst with dermal sinus. Pre contrast T1W image shows multiple foci in posterior and midline region of cerebellar folia in keeping with leakage of fat content from high signal dermoid cyst in occipital region of scalp through sinus.
