    (Aves Press Ltd, 2017) Çevik, Serdar; Yuksel, Ulas; Hanimoglu, Hakan
    Tension pneumocephalus (TP) which produces increased intracranial pressure and leads to neurological deterioration is a rare but life-threatening complication. A 59-year-old male patient who had undergone endoscopic sinus surgery was admitted to the emergency room with severe headache, nausea, and vomiting. Cranial computed tomography revealed pneumocephalus. Endoscopic surgery under general anesthesia was performed again, and a dural tear at the crista galli was identified and repaired using an autograft and fibrin glue. In same session, burr-hole drainage was also performed. He recovered after few days and was discharged. Therefore, following endoscopic sinus surgery, surgeons should be aware of the development of pneumocephalus, a rare but life-threatening complication.

    Traumatic isolated brain stem hematoma: a case report presenting with hemiparesis
    (Aves Press Ltd, 2018) Çevik, Serdar; Yuksel, Ulas; Ogul, Hayri; Şengül, Goksin
    Isolated brain stem hemorrhages are rare but have a high mortality rate after blunt head trauma. 56-year-old male admitted to the emergency room with weakness on the right side of his body, one day after the blunt head trauma. Right hemiparesis which is near to plegia (lower extremity motor weakness level was higher than upper extremity) was found on his neurological examination. T2-weighted images and susceptibility weighted images (SWI) of the magnetic resonance revealed heterogenous hyperintense lesion with hemorrhage at the left side of the pons. The patient was managed with conservative treatment; at three-month follow-up, near total recovery was observed on his neurological examination. As a conclusion, it could be said that brain stem contusion with hemorrhage could be kept in mind in patient with hemiparesis if the neurological deficit of the patient cannot be explained by supratentorial or spinal cord lesions.
