Pineal region pathology is relatively common and has a broad differential diagnosis. A systematic approach is therefore required in narrowing the differential for various pineal lesions. It is important to consider not only the pertinent imaging findings, but also the patient’s demographics and available history in order to improve diagnosis accuracy. The purpose of this educational exhibit is to present an algorithmic approach to pineal region lesions with emphasis on patient clinicopathologic findings and imaging features.

Using quiz format key differential diagnostic points will be highlighted in the discussion of each case. Systematic review will include following categories and cases: • Germ Cell Tumors – germinoma, teratoma, malignant NOS • Pineal Parenchymal Tumors – pineocytoma, pineoblastoma, pineal parenchymal tumor of intermediate differentioation, trilateral retinoblastoma • Neoplasms of adjacent tussies – tectal glioma, meningioma, Lymphoma • Metastasis • Papillary tumors of the pineal region • Non-neoplastic – pineal cyst, pineal lipoma, arachnoid cyst, epidermoid cyst, neurocysticercosis, cavum velum interpositum
