Pineoblastomas, which originate from the pineal gland, are extremely malignant tumors that grow quickly and aggressively. Because they spread so fast and the probability of longterm survival is poor, it is important to diagnose these tumors early. This article discusses magnetic resonance's role in imaging pineoblastomas. MR is particularly effective for this task due to its ability to visualize the pineoblastoma in three different planes, both before and after the administration of gadolinium.

Article Synopsis
- * These tumors often cause obstructive hydrocephalus and symptoms such as headaches, nausea, and impaired gait due to mass effect.
- * Diagnosis primarily relies on imaging, while biopsy is required for histologic confirmation, except for germinomas, which can be identified through specific tumor markers; treatments vary from surgery for benign tumors to additional chemotherapy and radiotherapy for malignant ones.

Pineal parenchymal tumors are rare neoplasms for which evidence-based treatment recommendations are lacking. These tumors vary in biology, clinical characteristics, and prognosis, requiring treatment that ranges from surgical resection alone to intensive multimodal antineoplastic therapy. Recently, international collaborative studies have shed light on the genomic landscape of these tumors, leading to refinement in molecular-based disease classification in the 5th edition of the World Health Organization (WHO) classification of tumors of the central nervous system.
