A report on a rare case of pineocytoma is presented. A 27-year-old woman visited our clinic because of a 3-month history of intermittent headaches and nausea. A CT scan revealed the presence of a marked obstructive hydrocephalus and mass without any contrast enhancement in the pineal region. Immediately, V-P shunting was performed and resulted in relief of all symptoms. Ventriculography showed a complete occlusion at the aqueductus Sylvii and filling defect at the posterior part of the 3rd ventricle. The patient was operated on in the prone position via infratentorial supracerebellar approach by suboccipital craniectomy on November 9, 1982. A grayish red-colored, well-defined solid tumor located at the pineal region was removed partially. The histopathological appearance of this tumor resembled the pattern of the normal pineal gland. Many cells exhibited a polar form, eosinophilic cytoplasm with the process often being directed toward a blood vessel. The cells around the central areas occupied by pale eosinophilic material were arranged like a "rosette". Combined chemo-radiotherapy was carried out after surgery. That is, a total dose of 4,825 rads to the whole brain was irradiated, and ACNU 140 mg and VCR 6 mg in total were administered intravenously and intermittently. After irradiation therapy, the tumor increased in size producing a ring-like enhancement effect as shown on repeated CT scans. During this time, she started to complain of blurred vision with Parinaud's sign. A second operation via interhemispheric approach by right parietal craniotomy was undergone, and the tumor was partially resected again on March 29, 1983.(ABSTRACT TRUNCATED AT 250 WORDS)

Papillary tumor of the pineal region is a rare neuroepithelial tumor characterized by papillary architecture and epithelial cytology, immunopositivity for cytokeratin and ependymal differentiation. It is considered grade II-III by the World Health Organization and was first described by Jouvet in 2003. We present a 34-year-old male with headaches, blurred vision and normal examination. Radiological study showed a nodulocystic lesion in the pineal region compatible with pineocytoma. Surgery was performed using an infratentorial supracerebellar approach, finding a cystic tumor in the quadrigeminal cistern which was completely resected. Histopathology reported a papillary tumor of the pineal region. The patient made good progress without adjuvant therapy, and after 57 months of follow-up he remained asymptomatic and free of recurrence. A review of the literature was performed to collect all the cases published with gross total resection and no complementary treatment. In conclusion, there is still much to be learned about the pathogenesis, prognosis and management of this tumor.
