Resumo

As metástases nas leptomeninges da espinal medula ocorrem raramente nos tumores sólidos e o prognóstico é bastante reservado. Os adenocarcinomas e os carcinomas de pequenas células são os grupos histológicos mais envolvidos no que se refere aos tumores pulmonares. Um homem de 58 anos com história de carcinoma de células escamosas do pulmão com inversão mediastínica e metástases cerebrais apresenta lombalgias e fraqueza em ambos os membros inferiores. A RMN da coluna vertebral revelou espessamento na espinal medula e múltiplos nódulos do grupo das fibras da cauda equina. Tanto quanto sabemos, trata-se do segundo caso relatado de carcinoma pulmonar de células escamosas que apresenta metástases nas leptomeninges da espinal medula.

Palavras-chave: Espinal medula, leptomeninges, metástases, ressonância magnética nuclear.

 

 

Spinal leptomeningeal metastasis in a patient with squamous cell lung cancer

Abstract

Spinal leptomeningeal metastasis occurs rarely in solid tumors, and the prognosis is extremely poor. Adenocarcinomas and small-cell carcinomas are the most common histological type detected among lung tumors. A 58-year-old man with a history of squamous-cell lung carcinoma with mediastinal invasion and brain metastasis was examined because of his low back pain and weakness in both lower limbs. Spinal MRI revealed subpial enhancement in the spinal cord; and innumerable nodules with thickening of the cauda equina fibres. To our knowledge, this is the second reported case of squamous cell lung cancer with spinal leptomeningeal metastasis.

Key-words: Spinal, leptomeningeal, metastasis, lung cancer, magnetic resonance imaging.
