TI  - Magnetic Resonance Imaging Findings of Intracranial Dural Metastases
AB  - BACKGROUND/AIMS: To evaluate the magnetic resonance imaging (MRI) findings of intracranial dural metastases (IDM) due to various cancers. MATERIALS AND METHODS: Fifty-six male and thirty female patients (total: 86) aged 2-94 years (mean: 58.10±16.32 years) diagnosed with IDM between April 2010 and May 2020 were included in this retrospective study. Dural tumoral involvement patterns [focal, multifocal, diffuse linear, diffuse linear and nodular (mixed)], bone involvements (focal, diffuse, none), tumoral involvement areas (dural; bone and dural; parenchymal and dural; bone, dural, and parenchymal), locations (supratentorial, infratentorial), leptomeningeal involvement and the presence of perineural spread were evaluated in these cases. RESULTS: IDM were most commonly observed in head and neck cancers (23.3%), lung cancer (17.4%), and breast cancer (15.1%). Focal pattern was observed in 55.8% of the dural tumoral involvements while 16.3% were multifocal, 16.3% diffuse linear and 11.6% mixed pattern. Fiftyseven percent of the cases involved had bone and dural area involvement, whereas 24.4% had parenchymal and dural involvement, 13.9% bone, dural and parenchymal combined involvement, and 4.7% only had dural involvement. Supratentorial involvement alone was seen in 39.5% and infratentorial involvement alone was observed in 7% of the cases, while 53.5% of the cases had both supratentorial and infratentorial involvement. In 38.3% of the cases found to have dural metastasis, cerebral parenchyma invasion was observed. Leptomeningeal involvement was observed in 41.9% of the cases whereas 9.3% had perineural spread. CONCLUSION: IDM are more commonly observed in the male gender and in head and neck, lung and breast cancers. IDM are more commonly accompanied by bone or parenchymal involvement, while isolated dural metastases are less frequently observed.
