A,B) magnetic resonance imaging (MRI) of the brain shows a well-defined lesion measuring 1.6cm x 1.5cm x 1.6cm in the pineal region. The lesion was hyper intense on T1 and T2 weighted images; C) the lesion shows no post-contrast enhancement; D) the lesion shows intense diffusion restriction; E) the postoperative MRI shows complete removal of cyst; F) histopathology (haematoxylin & eosin stain) shows cyst wall lined by stratified squamous epithelium with abundant luminal lamellated keratin consistent with epidermoid cyst

The lesion was hyper intense on T1 and T2 weighted images (Figure 1A and Figure 1B) with no post-contrast enhancement (Figure 1C). It also showed intense diffusion restriction (Figure 1D). The postoperative MRI showed complete removal of cyst (Figure 1E). Histopathology examination confirmed pineal epidermoid cyst (Figure 1F).
