Fig 1. A, Sagittal, noncontrast T1WI demonstrates an extensive SDH dorsal to the clivus (black arrows). Closer inspection reveals an inferiorly projecting flow void extending from the suprasellar region into the sella turcica (open arrow), which raises the possibility of an aneurysm of the AcomA. Increased signal intensity seen along the roof of the sella (white arrow) is consistent with hemorrhage dissecting along the diaphragma sella. B, Axial T2WI demonstrates a saccular outpouching (white arrow) consistent with an aneurysm arising from the AcomA.

Fig 2. Conventional angiogram obtained from a right internal carotid artery injection (A) precoiling AP view and (B) unsubtracted postcoiling lateral view demonstrates an aneurysm of the AcomA (black arrows) projecting inferiorly into the expected location of the sella turcica. Note the inset skull x-ray in the upper right-hand corner showing the coil mass in the sella turcica.

Fig 3. Sagittal noncontrast T1WI MR imaging of the cervical, thoracic, and upper lumbar spine demonstrates a circumferential high signal intensity (arrows) in the intradural extramedullary space consistent with a SDH of the spine.
