title: Unusual aetiology of malignant spinal cord compression.
abstract: Malignant spinal cord compression (MSCC) is an oncological emergency requiring rapid diagnosis and treatment to prevent irreversible spinal cord injury and disability. A case is described in a 45-year-old male with renal cell carcinoma in which the presentation of the MSCC was atypical with principally proximal left leg weakness with no evidence of bone metastasis. This was due to an unusual aetiology of the MSCC as the renal carcinoma had metastasised to his left psoas muscle causing a lumbosacral plexopathy and infiltrated through the intervertebral disc spaces, initially causing left lateral cauda equina and upper lumbar cord compression, before complete spinal cord compression. This case illustrates the varied aetiology of MSCC and reinforces the importance of maintaining a high index of suspicion of the possibility of spinal cord compression.
