Abstract

The filum terminale is an exceptional location for isolated hemangioblastoma. Only five cases are reported in literature, prior to the magnetic resonance imaging era. A 57-year-old man was referred to our Department with a prolonged history of progressive back pain, particularly severe when recumbent, and recurrent unilateral sciatalgia. Computed tomography demonstrated a non-homogeneous mass at L4 level. Magnetic resonance imaging displayed earliness and homogeneous enhancement of the mass with tortuous vessels above the rostral pole of the tumour, suggesting the diagnosis of a vascular tumour. The tumour was totally removed. Histological examination confirmed the hemangioblastoma diagnosis. The case indicates that hemangioblastoma, although uncommon, must be taken into consideration in cauda equina tumour diagnosis, and also emphasises the specificity of magnetic resonance features.
