Differentials for this appearance:
1 Pinealoma (pinealogerminoma /disgerminoma); 2 Pineal teratoma (second most common pineal tumour), 3 Pineal cell tumours (pineocytoma / pineoblastoma); 4 Isolated metastasis eg melanoma or primary glioma considered less likely.
Solid dense pineal region mass with no discernible enhancement. Two small foci of calcification lie to the left of the lesion posterosuperiorly. This likely represents normal pineal calcification.
There is impression on the midbrain, posterior aspect of the third ventricle and aqueduct, with early obstructive hydrocephalus and dilatation of the supratentorial ventricles and temporal horns.
