“…[1,2,4,6] Precise physical examination and neuroimaging can be useful for differential diagnosis Computed tomography (CT) scans demonstrate the lesion as an extracranial, encapsulated, low-density mass without enhancement (known as a fluid-containing cyst) that is sometimes accompanied by lytic bone lesions. [2,7] Magnetic Resonance Imaging (MRI) is the most reliable and accurate test [4] and shows the lesion as a low-and highintensity mass on T1-weighted and T2-weighted images, respectively. [3,[7][8][9] It has been recommended to perform CT or MRI before surgery [9] to determine the extension of the cyst and the presence of a lytic bone lesion.…”
