From: Rathke’s cleft cyst discovered with ruptured anterior communicating artery aneurysm: a case report
Non-contrast computed tomography of the head performed on initial presentation showing high-density signals in the basal cisterns suggestive of acute subarachnoid hemorrhage (B, C, red arrow). There is a nonspecific hypodensity in the sellar region (A, red asterisk). Cerebral digital subtraction angiogram performed during the initial presentation shows a bi-lobed secular aneurysm of the anterior communicating artery with the aneurysm sac measuring 3.7 × 4 mm anteriorly and laterally (D, white arrow)
