"Recurrent Pleomorphic Xanthoastrocytoma Presenting with Diffuse Leptomeningeal Spread".

Abstract

We have read with great interest the recent paper by Grigsby-Rocca et al regarding recurrent pleomorphic xanthoastrocytoma (PXA) with leptomeningeal dissemination. While acknowledging the challenges in managing such cases, we wish to highlight the role of radiotherapy for symptom palliation and potential life extension. We report a case of a 27-year-old woman with recurrent anaplastic PXA and diffuse leptomeningeal spread, who was offered radiotherapy to the spinal axis. Initially presenting with headaches and seizures, she underwent surgical excision, postoperative radiotherapy, and temozolomide. Despite initial disease control, subsequent recurrences required additional surgeries and systemic therapies. With disease progression to leptomeningeal spread, radiotherapy was administered, resulting in clinical stability. This case underscores the importance of considering palliative radiotherapy to improve quality of life and potentially prolong survival in patients with recurrent PXA and leptomeningeal dissemination.
