“…The commonest site of localization of PMA is in hypothalamo-chiasmatic region and only a few cases have been reported in cerebral cortex. There has been only a single case report of PMA in an adult male of 24 years involving posterior temporal lobe (3). Thirdly, anaplastic nuclear features observed in present case have never been reported in PMA.…”

BACKGROUND AND IMPORTANCE Pure aqueductal tumors are extremely rare and may lead to death, regardless of histopathology. We report the first case of pure aqueductal pilomyxoid astrocytoma in an adult woman with arrested hydrocephalus. Endoscopic tumor resection for securing aqueductal patency followed by chemotherapy allowed control of both the tumor and the hydrocephalus. CLINICAL PRESENTATION: A 20-year-old woman presented with mild cognitive dysfunction and marked ventricular dilatation. She had no preoperative symptoms of intracranial hypertension, and her head circumference was more than 2 SDs above the 98th percentile. The aqueduct of Sylvius was entirely occupied by a neoplastic lesion with 2 periventricular nodules at the wall of the third ventricle and anterior horn of the right lateral ventricle. She was treated successfully with endoscopic tumor resection followed by chemotherapy, and the patency of the aqueduct of Sylvius was secured throughout the duration of treatment. CONCLUSION: Pure aqueductal tumors may be an appropriate indication for endoscopic tumor resection to secure the aqueductal patency of cerebrospinal fluid. This case demonstrates the surgical technique of a combined rigid-flexible endoscopic transforaminal approach, which was a useful surgical intervention for the management of this patient.
