%X BACKGROUND: Malignant melanoma is a highly invasive tumor with very poor prognosis. Common metastases of MM are noted in lungs, Central nervous system, liver, lymph nodes and isolated spinal metastases are extremely rare. To our knowledge only one case of isolated lumbar spinal metastases of MM was reported.
METHODS: An 80-year-old female presented with pain at upper thoracic spine and progressive weakness of bilateral lower limbs. She gives history of recurrent MM of nose, for which she underwent excision of tumor twice. On examination she had spastic gait with exaggerated lower limb reflexes and lower limb motor grade of 3/5. The MRI scan of thoracic spine revealed lobulated enhancing mass involving the right half of the T3 vertebral body and corresponding posterior elements. The patient underwent palliative spinal decompression and excision of tumor. Histopathology confirmed MM. The PET scan done post operatively ruled out any other sites of metastases.
CONCLUSIONS: Though the incidence of isolated manifestation of spinal metastases of MM is extremely rare, clinical suspicion and advanced imaging can help to diagnose early. The treatment strategy should be guided by current neurological status, nature of the tumor, presence of mechanical instability and patient's fitness to undergo surgical intervention.
CONCLUSIONS: Patient diagnosed with MM should be closely followed up even in absence of any recurrence at the primary site. Surgical decompression can improve neurological symptoms and decrease pain to improve quality of life even at advanced stage of the disease.
