In this case-based review, the authors analyzed relevant literature with an illustrative patient of theirs about subdural hematoma secondary to dural tear at spinal surgery. Intracranial hypotension is a condition of decreased cerebrospinal fluid volume and pressure. Even though intracranial hypotension is temporary and can be managed conservatively, it may progress and result in subdural fluid collections, hematoma formations, "brain sagging or slumping" states, syringohydromyelia, encephalopathy, coma, and even death. ⋯ Ten of 21 (48%) patients were treated conservatively. Late-onset neurological findings should not prevent the evaluation of cranial vault with computed tomography and magnetic resonance imaging. Spinal dural tear should be more aggressively treated instead of suture alone approach, when recognized in older patients during the spinal surgery.

Case Reports
Pseudoaneurysm in the Internal Maxillary Artery Occurring After Endoscopic Sinus Surgery.
Pseudoaneurysm is defined as blood leaking out of a vessel that does not have true 3 arterial walls like a true aneurysm, and is susceptible to rupture. Only 4 patients of pseudoaneurysm after endoscopic sinus surgery have been reported so far in English literature. Recently, the authors encountered a pseudoaneurysm in the internal maxillary artery after endoscopic sinus surgery, which was immediately and successfully managed with endovascular embolization. There was no bleeding or complications 6 months after the embolization.
