case_images: She was referred to the neurosurgical service for a right parietal tumor on metastatic workup [Figure 1] and was scheduled for craniotomy for tumor resection.
case_images: (a) Postoperative contrast cranial computed tomography (CT) showing postoperative changes at the right parietal area, no evidence of enhancing tumor, and no evidence of hydrocephalus; (b) same CT showing pseudomeningocele formation and outward displacement of the bone flap; (c) cranial CT, bone window, showing dislodged bone flap; (d) 3D reconstruction of the cranial CT highlighting the dislodged bone flap.
