| Popis: | A dark pigmented intramedullary mass is very rarely encountered in daily practice, and poses a diagnostic challenge. Several entities have to be considered, including melanin-containing tumours (melanotic ependymoma and melanotic schwannoma) and melanocyte-containing tumours (melanocytoma, primary melanoma and melanoma metastases). The case is presented of a 47 year-old male with a pigmented intramedullary tumour located at T7-T8 level. Magnetic resonance images (MRI) revealed a tumour with hyperintensity on T1 and hypointensity on T2. The tumour was resected partially and treated with adjuvant radiotherapy. The diagnosis of primary intramedullary melanoma (PIM) was established based on histology and the absence of other lesions outside of the CNS. A literature review is presented on the other 26 PIM cases reported. PIM are extremely rare tumours, but are the most frequent cause of pigmented intramedullary tumour. Complete surgical resection is the treatment of choice whenever possible, followed by radiotherapy. |
