Dural and calvarial metastasis of thyroid follicular carcinoma mimicking Sindou type 6 parafalcine meningioma

Fifty-two years, NID type-2 diabetic female was admitted with progressive headache, enlarging, pulsatile midline mass, dizziness, and numbness of extremities. Physical examination revealed only hypoesthesia in the upper left extremity C7-dermatome. Preoperative computed tomography revealed eroded pa...

Summary:Fifty-two years, NID type-2 diabetic female was admitted with progressive headache, enlarging, pulsatile midline mass, dizziness, and numbness of extremities. Physical examination revealed only hypoesthesia in the upper left extremity C7-dermatome. Preoperative computed tomography revealed eroded parafalcian dural mass and caused a round 7 cm calvarial defect over the superior sagittal sinus (SSS) and another left parietal 1.2 cm satellite mass. Magnetic resonance imaging revealed an extra-axial, diffuse heterogeneous gadolinium-enhanced, well-circumscribed lesion invading the SSS and Trolard veins (bilaterally). Supratotal resection 1 cm from the tumor borders was performed, histopathology suggested papillary thyroid carcinoma follicular variant. The euthyroid patient underwent total thyroidectomy, and final pathology revealed invasive TFC. 5-year follow-up was uneventful without recurrence or new metastasis. Parafalcian meningioma classification was reviewed for the best surgical approach. The definitive diagnosis of meningioma should be established with histopathological analysis. TFC should be included in the differential diagnosis in cases of extra-axial tumors.
