Imaging plays an essential role in the evaluation of patients after cranial surgery. Postoperative infection and hemorrhage are common complications after cranial surgeries. Life-threatening complications (like tension pneumocephalus and paradoxical herniation) must be identiϑied rapidly at imaging to secure a favorable prognosis. This cross-sectional study included 250 patients who underwent varient neurosurgical operations and were imaged for the developed postoperative complications using Computed Tomography(CT), Magnetic Resonance Imaging(MRI) with and without contrast. We reviewed the common normal and abnormal ϑindings in post-operative neurosurgical patients. The expected postoperative CT and MRI appearances of these procedures are discussed, followed by complications. These include hemorrhage, tension pneumocephalus, wound/soft tissue infection, bone ϑlap infection and extradural abscesses. Complications speciϑically related to craniectomies include extracranial herniation, external brain tamponade, paradoxical herniation, and trephine syndrome. In our study165 male; 58 % and 85 female; 42 % were included; age range (6months-69 years), mean age 34.7 ± 2.9 years. 130 patients underwent craniotomy, infection (23%) was the most dominant complication followed by intra cranial hemorrhage (19 %). So to conclude;radiologist must know how to recognize postoperative complications and differentiate them from expected normal ϑindings because an early and accurate diagnosis is important for proper postoperative care.Computed tomography is fast, cost effective, and easily accessible for ϑirst-line imaging. Magnetic resonance imaging has higher sensitivity for detecting postoperative infection and ischemia
