Radiographic Pearls in the Evaluation of an Extradural Thoracic Meningioma: A Case Report

Abstract

Spinal meningiomas are the most common of adult spinal tumors. Spinal meningiomas account for up to 45% of all intradural spinal tumors in adults and up to 25% of all spinal tumors. While spinal meningiomas are traditionally classified as intradural lesions, up to 14% may have an extradural component. Preoperative evaluation and directed use of imaging techniques are key in these rare but observed cases, to accurately diagnose and direct therapy. In this report, the authors present a case of a 61-year-old female with an incidentally found, exclusively extradural thoracic meningioma treated with surgical resection, highlighting key radiographic pearls in the evaluation of these uncommon lesions.

Intradural extramedullary granular cell tumour in a cat

“…The peculiar appearance of the vertebral bodies adjacent to the mass could be related to a slow growth of this type of GCT. Vertebral bone remodelling is indeed described in other slowgrowing intraspinal tumours such as meningiomas and PNST (Kraft et al 2007, Haranhalli et al 2017.…”

Spinal extradural meningioma: Report of two cases

“…On T2-WI, the latter two lesions typically show high signal intensity with cystic change and inhomogeneous enhancement. [ 8 ] Because these lesions are extradural, they frequently have a foraminal and paravertebral extension, which leads to further malignant diagnoses such as spinal metastases, extradural lymphoma, or a malignant nerve sheath tumor.…”

Extradural Spinal Lymphoplasmacyte-Rich Meningioma in the Thoracic Spine: A Case Report and Literature Review

“…Spinal meningiomas are common spinal neoplasms, accounting for 25%–46% of primary spinal tumors ( 4 ). Meningiomas arising in the spine account for 12% of all the meningiomas ( 5 ). Most spinal meningiomas have an intradural extramedullary location but can sometimes extend to the extradural space.…”
