Extramedullary intradural spinal tumors

Extramedullary intradural tumors (TIDEMs) are mostly benign but can lead to spinal cord compression responsible for neurological deficits.This retrospective descriptive and analytical study covers 31 patients operated on between 2018 and 2025 in the neurosurgery department of the Cheikh Zaid International University Hospital in Rabat. The mean age was 50.4 ± 17.7 years with a slight female predominance (sex ratio F/H = 1.21). The dominant symptoms were spinal pain (80.6%) and motor disorders (54.8%). Thoracic localizations were the most frequent (45.16%). Meningiomas (48.4%) and schwannomas (32.26%) were the main histological types. A significant correlation was found between tumor topography, MRI features and histological type.Macroscopically total excision was achieved in 96.77% of cases, with significant neurological improvement according to Fränkel and Karnofsky scores. These results underline the value of optimized neurosurgical management and an integrated diagnostic approach.
