title: Osteolytic skull metastasis with dural involvement from a papillary thyroid carcinoma.
abstract: Skull metastatic tumors are relatively rare medical entities and originate most often from the lungs, breast or prostate. We report a case of a 76-year-old woman who presented with a bulging, well-circumscribed mass on the right side of the forehead. Neuroimaging of the cranium detected an osteolytic lesion measuring 7 cm in the largest diameter while propagating outwards and intracranially. A thorough medical history revealed that patient had undergone surgery for invasive breast ductal carcinoma and also for a well-differentiated thyroid carcinoma 13 years ago. Considering patients medical history metastatic breast carcinoma was suspected. After a frontal craniotomy the tumour tissue was totally resected. Histological examination revealed metastatic papillary carcinoma characterized by ground-glass nuclei with intranuclear pseudo inclusion and nuclear grooves. We report clinical and neuroradiological features of this uncommon lesion and discussed the differential diagnosis of skull osteolytic lesion together with the treatment management.
