Pseudosubarachnoid hemorrhage (pseudoSAH) is a radiologic finding that resembles true subarachnoid hemorrhage on computed tomography, even though there is no actual bleeding. It can occur in various conditions, such as intracranial hypotension, brain edema, or abnormal spread of contrast material, and may be mistaken for real hemorrhage. We experienced a rare case of pseudoSAH that appeared after a cervical epidural block. The finding was likely caused by unintentional dural puncture and temporary diffusion of contrast medium into the subarachnoid space. Recognizing pseudoSAH is important because its imaging features can mimic true hemorrhage, but its clinical course and management are very different. This case emphasizes the need to interpret radiologic findings together with clinical features and cerebrospinal fluid analysis, and to be aware that pseudoSAH may occur as a transient and benign phenomenon after cervical spine procedures.
