Sellar Atypical Teratoid/Rhabdoid Tumor Presenting with Subarachnoid and Intraventricular Hemorrhage

Atypical teratoid/rhabdoid tumors (ATRT) are uncommon malignancies of the central nervous system and are often difficult to distinguish radiographically and pathologically from other common tumors. We present the first case of sellar ATRT presenting with subarachnoid hemorrhage (SAH) and intraventricular hemorrhage (IVH).

A 62-year-old woman, who had presented with symptoms of headache, diabetes insipidus, hypothyroidism, and seizures, was found to have a sellar tumor with hemorrhagic transformation. Surgical resection was performed. The pathological examination findings were consistent with ATRT. Despite early surgical intervention, she later died before starting craniospinal radiotherapy and chemotherapy.

To the best of our knowledge, although known to present with intratumoral hemorrhage, to date, no cases of sellar ATRT have presented with SAH or IVH have been reported. Considering our finding that ATRT can present with SAH and IVH, establishing the correct diagnosis using radiographic imaging, gender, pathological findings, and molecular markers is paramount for speedy treatment and management.
