OBJECTIVE: This retrospective study was conducted to investigate the relationship between the superior sagittal sinus (SSS) to bone flap distance and clinical outcome in patients with traumatic brain injury (TBI) who underwent decompressive craniectomy (DC). METHODS: A retrospective review of medical records identified 255 adult patients who underwent DC with hematoma removal to treat TBI at our hospital from 2016 through 2017; of these, 68 patients met the inclusion criteria and underwent unilateral DC. The nearest SSS to bone flap distances were measured on postoperative brain computed tomography images, and patients were divided into groups A (distance ≥20 mm) and B (distance < 20 mm). The estimated blood loss (EBL) and operation time were evaluated using anesthesia records, and the time spent in an intensive care unit (ICU) was obtained by chart review. The clinical outcome was rated using the extended Glasgow Outcome Scale (GOS-E) at 3 and 6 months postoperatively. RESULTS: The male to female ratio was 15:2 and the mean subject age was 55.12 years (range, 18–79 years). The mean EBL and operation times were significantly different between groups A and B (EBL: 655.26 vs. 1803.33 mL, p < 0.001; operation time: 125.92 vs. 144.83 min, p < 0.001). The time spent in the ICU and GOS-E scores did not differ significantly between the groups. CONCLUSION: We recommend that when DC is indicated due to TBI, an SSS to bone flap distance of at least 20 mm should be maintained, considering the EBL, operation time, and other outcomes.

A 19-year-old man presented with bitemporal hemianopsia and was found to have a large sellar and suprasellar tumor, resembling a pituitary macroadenoma. Emergency transsphenoidal approach was attempted because of rapid visual deterioration with headache. However, the approach was complicated and stopped by uncontrolled hemorrhage from the tumor. After conventional cerebral angiography and recognition of an unusual pathology, transcranial approach was achieved to prevent permanent visual loss. The final pathological diagnosis was pituicytoma with epithelioid features. Pituicytoma is a rare low-grade tumor (WHO Grade I) of pituicytes involving the sellar and suprasellar region, and originating from special glial cells of the neurohypophysis. Because of the high vascularity, the firm consistency, and invasion to surrounding neurovascular structures, a pituicytoma should be included in the differential diagnosis of a mass in the sellar and suprasellar area if the tumor shows high enhancement with vascular components. We report a case of rare pituicytoma mimicking a pituitary macroadenoma with massive hemorrhage to disturb surgery.
