RESUMO
Radicular pain on the arm often referred to cervical disc problems. If cervical MRI is normal, then it is necessary to rule out peripheral nerve tumor. A 54-year old man presented with radicular pain in his left arm, investigated for cervical disc problems, with normal cervical MRI. Examination shows a positive Tinel’s sign on the proximal part of his left arm. Focal MRI revealed a lobulated tumor in the radial nerve 1.5 cm in diameter. The patient was operated and the tumor was completely removed. Histopathology confirmed the diagnosis of schwannoma.

One case of unsuspected schwannoma is reported in a 69-year old man with chronic lumbosacral pain. The tumour had been mistaken for a lumbar lipoma for a decade. The definitive diagnosis was established after surgery based on the characteristic histopathological findings. The purpose of this report is to alert primary care physicians to peripheral sheath nerve tumours, in addition to highlight the role of pain and image features in the suspicion of tumours with longterm evolution.
Se relata un caso de schwannoma insospechado en un hombre con dolor lumbosacral crónico. El tumour había estado equivocado por el lipoma lumbar durante una década. El diagnóstico definitivo puede establecerse después de la cirugía, con base en los resultados histopatológicos característicos. El propósito de este informe es dar énfasis al conocimiento de médicos del cuidado primario sobre los tumoures de la vaina de nervios periféricos, y resaltar el papel del dolor e de las imágenes en la sospecha de estos tumoures que evolucionan con equívocos diagnósticos a largo plazo.
