185:". Up to 5% of patients with hereditary retinoblastoma are at risk of developing trilateral retinoblastoma. This tumor combination is more aggressive than an isolated pineoblastoma. Prognosis of patients with trilateral retinoblastoma is dismal, only a few patients have survived more than 5 years after diagnosis; all survivors were diagnosed with small tumors in a subclinical stage. Recent advances in (high-dose) chemotherapy treatment regimens and early detection have improved survival of patients with trilateral retinoblastoma to up to 50%. 63: 221: 99: 313:
Pineoblastomas are very aggressive tumors. 5-year survival for patients with pineoblastomas is around 58%. Prognosis for patients under 5 years old is lower, between 15 and 40%. Disseminated disease at diagnosis is also associated with worse outcomes. When pineoblastomas occur with retinoblastomas,

Pineoblastomas typically occur at very young ages. One study found the average age of presentation to be 4.3 years, with peaks at age 3 and 8. Another cites cases to more commonly occur in patients under 2 years of age. Rates of occurrence for males and females are similar, but may be slightly more

and peripheral calcification of the pineal gland. On MRI, pineoblastomas again appear as masses with heterogenous enhancement. They often appear hypo- to isointense on T1 and slightly hyperintense on T2-weighted images. Some areas of necrosis or hemorrhage may be seen as well. PET-CT has also been

Initial treatment for pineoblastoma often includes a shunting procedure to redirect accumulated cerebrospinal fluid secondary to obstructive hydrocephalus. This shunt can help manage increased intracranial pressure and relieve some symptoms. Surgery to remove the tumor is associated with better

Due to the aggressive nature of the disease, tumor spread at the time of diagnosis is common. Pineoblastomas often invades locally, with spread to the head and spine seen in 25–41% of patients. While CNS spread is relatively common, these tumors rarely cause distant metastases.

Biopsy is required for diagnosis. Pineoblastomas appear as high grade, highly cellular, small blue cells histologically. Features of aggressive malignancies can be seen, like high nucleus-to-cytoplasm ration, poorly differentiated cells,

Complete gross tumor resection is associated with improved prognosis, but is difficult and rare to achieve. Radiation therapy after surgery is also linked to improved survival.
