Intracerebral Solitary Fibrous Tumor in Collision With Metastatic Colonic Adenocarcinoma.
Cureus
November 2024
Neurosurgery, Novant Health Presbyterian Medical Center, Charlotte, USA.
A collision tumor is a rare neoplastic lesion consisting of two or more coexisting, distinct cell line entities. In this report, we present the case of a 56-year-old male patient with a history of colon cancer who presented to the emergency room with visual deficits that had started about eight months earlier. An ophthalmologic examination reported left homonymous hemianopsia, prompting a brain MRI, which showed a right posterior temporal extra-axial mass concerning intracerebral metastatic colon cancer, in consideration of patient history.

Although conducted electrical weapons (CEWs) such as the Thomas A. Swift's Electric Rifle (TASER) provide a less lethal means for subduing persons than firearms or stun guns, they have the potential to cause adverse injury. This report discusses the intracranial penetration of a TASER dart.

Department of Neurosurgery, University of California, Sacramento, California, United States.
Background: Orbital roof fractures are often the result of high-velocity collisions and are seen in 1-9% of patients with craniofacial trauma. Although the majority of orbital roof fractures are displaced superiorly, a subset results in inferior displacement of fracture fragments, posing a risk for muscle/nerve entrapment and possible blindness. Many of these patients have severe traumatic brain injury (TBI) and, in addition to orbital fractures, also have elevated intracranial pressure (ICP).

This study aimed to clarify the differences between the previously reported mechanisms of sports-related concussion (SRC) injuries without a loss of consciousness in contact and collision sports and the mechanisms of SRC injuries in our cases. Based on two videos of SRC injuries occurring during a men's rhythmic gymnastics competition (three people were injured), the risk of SRC occurrence was estimated from various parameters using a multibody analysis and eight brain injury evaluation criteria. In the present study, the three SRC impacts that occurred in men's rhythmic gymnastics showed significant characteristics in duration compared to previously reported cases in the contact sports.

Klinikum Darmstadt GmbH, Institut für Radionkologie und Strahlentherapie, Darmstadt, Germany.
Purpose: Noncoplanar beams and arcs are routinely used to improve dosimetry for intracranial cases, but their application for extracranial cases has been hampered by the risk of collision. This has led to conservative beam selection whose impact on plan dosimetry has not been previously studied.
Methods And Materials: A full-body 3-dimensional patient surface was acquired using optical cameras for a single lung patient at the time of computed tomography simulation.
