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.
(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.
