Concurrent multiple cerebral cavernous malformations and cauda equina paraganglioma: illustrative case.
J Neurosurg Case Lessons
August 2024
Departments of Neurosurgery, St George Hospital, Kogarah, New South Wales, Australia.
Background: Cauda equina neuroendocrine tumors (CENETs), previously known as cauda equina paragangliomas, and multiple cerebral cavernous malformations (CCMs) are uncommon conditions affecting the central nervous system. To the authors' knowledge, they have not been reported in the same patient.
Observations: The authors present the case of a 45-year-old male with CENET and concurrent incidental MRI findings of multiple CCMs.
Cauda equina neuroendocrine tumor: a report of three cases and review of the literature with focus on differential diagnosis and postoperative management.

Introduction: Cauda equina neuroendocrine tumors (CENETs), previously described as cauda equina paragangliomas (PGLs) are rare and well-vascularized benign entities which can be often misdiagnosed with other intradural tumors more common in this anatomical site, such as ependymomas and neurinomas. We describe three cases of CENETs observed at our institution with particular focus on differential diagnosis and postoperative management. Since the lack of guidelines, we performed a literature review to identify factors that can predict recurrence and influence postoperative decision making.

Hand2 is a core transcription factor responsible for chromaffin cell differentiation. However, its potential utility in surgical pathology has not been studied. Thus, we aimed to investigate its expression in paragangliomas, other neuroendocrine neoplasms (NENs), and additional non-neuroendocrine tumors.

Lumbar paragangliomas are rare neuroendocrine neoplasms arising from specialized neural crest cells in the cauda equina/filum terminale region. They are difficult to diagnose radiologically and can be difficult to treat surgically if they secrete catecholamines. A 38-year-old woman presented with three and a half years of increasing lower back and sacrum discomfort.

Cauda equina neuroendocrine tumors (CENET) are rare neoplastic processes that develop in the cauda equina or filum terminale region of the spinal cord, which in previous incarnations of the World Health Organization (WHO) classification of the central nervous system (CNS) tumors were designated as paragangliomas. The change of terminology was carried out due to the rarity of the condition, its specific place of origin, the non-specific clinical and imaging characteristics with which the tumors present, and differences in biological properties (secretion and progression) as well as some minor differences in immunohistochemical protein expression patterns. Herein, we present a case of a male patient in his sixties who presented to us for a histopathological consultation of a previously excised tumor, which was grossly well-demarcated and connected to a nerve root in the cauda equina region.
