Pseudo-subarachnoid hemorrhage (PSAH) is an infrequent entity characterized by findings in non- contrast head computed tomography that mimic subarachnoid hemorrhage, but without evidence of blood products in further studies. It has been associated with multiple etiologies, with hypoxic ischemic encephalopathy following cardiac arrest and cardiopulmonary resuscitation as the leading cause in literature. Clinical context and attenuation levels measured in Hounsfield Units should be taken into consideration when establishing the differential diagnosis between these entities. The case of a patient with PSAH of multifactorial etiology is presented.
