Comparative Study
A comparison of subgaleal versus subperiosteal dissection in open cranial vault expansion for sagittal craniosynostosis.
The aim of this study was to evaluate surgical outcomes for patients with sagittal craniosynostosis undergoing open cranial vault remodeling with a modified pi procedure comparing subgaleal versus subperiosteal dissection. ⋯ Open posterior and middle cranial vault expansion is a safe and efficient method of open cranial vault expansion in sagittal craniosynostosis regardless of the plane of dissection. Elevation of the scalp flaps in the SG plane is a minor technical modification that can reduce blood loss and operative times.

Case Reports
Data-driven identification of the regions of interest for fiber tracking in patients with brain tumors.
We investigated the added value of combining information from direction-encoded color (DEC) maps with high-resolution structural magnetic resonance imaging scans (T1-weighted images [T1WIs]) to improve the identification of regions of interest (ROIs) for fiber tracking during preoperative planning for patients with brain tumors. ⋯ Combining the information from diffusion-derived color-encoded maps with high-resolution anatomical details from structural imaging (T1WI-DEC map), especially in patients with brain tumors, could be useful for accurate identification of the ROIs.

The purpose of this study was to develop and validate a nomogram to predict overall survival (OS) for adult patients with primary intramedullary spinal cord grade II/III ependymoma (PISCGE). We also elucidated the effectiveness of postoperative radiotherapy for this disease. ⋯ We built the first nomogram model and risk classification system for PISCGE patients. Our model accurately estimated the individual OS probability of these patients, and proposes different treatment approaches for patients based on the risk classification system. Furthermore, from our findings, radiotherapy confers no survival advantage to these patients.

Tuberculosis is characterized by cold abscess, which classically lacks the usual signs and symptoms of inflammation. This case report highlights an atypical presentation of tuberculous cold abscess in the form of appearance of massive swelling in the back overnight after a blunt trauma, mimicking post-traumatic hematoma. ⋯ Appearance of massive swelling overnight in patients with cold abscess has not been described in the literature. While evaluating an atypical presentation such as sudden post-traumatic swelling over the thoracolumbar area, the clinician should keep a differential diagnosis of tuberculous abscess and investigate clinicoradiologically to rule out tuberculosis, especially in developing countries.

Esophageal perforation represents a rare but potentially life-threatening complication of an anterior cervical diskectomy and fusion (ACDF). Delayed presentations of esophageal perforation more than 10 years following surgery are exceedingly rare and difficult to diagnose. Here, we discuss the case of an 80-year-old man who presented to the emergency department with progressive dysphagia 15 years after his ACDF. ⋯ This case emphasizes the importance of considering an esophageal perforation in patients who present with dysphagia at any interval following an ACDF, even in the extremely delayed setting. Furthermore, this is the first report, to the best of our knowledge, using a supraclavicular artery island fascial flap to reconstruct an esophageal perforation following an ACDF, and we introduce a novel strategy for managing these complicated injuries.
