Neurosurgical Injuries Associated with Recreational Horseback Riding: A 6-year Retrospective Analysis.

Introduction: Horseback riding can cause severe brain and spinal injuries. This study aimed to identify the spectrum of neurosurgical injuries related to recreational horseback riding.

Methods: A retrospective study was performed utilizing the University of Puerto Rico neurosurgery database to identify patients who were consulted to the neurosurgery service between 2018 and 2023 after a horse fall during recreational activities.

Aggressive Diffuse Leptomeningeal Glioneuronal Tumor in a Pediatric Patient Presenting With Mismatch Repair Gene Mutations.

Diffuse leptomeningeal glioneuronal tumor (DLGNT) is a rare primary central nervous system tumor. We present the case of a five-year-old male patient with a rapid progression of a thoracic DLGNT. Initial presentation and workup confirmed acute communicating hydrocephalus requiring a ventriculoperitoneal shunt.

Spine Trauma Secondary to Diving Accidents: A Seven-year Retrospective Study in Puerto Rico.

Objective: Review the profile of patients with spinal trauma after diving accidents referred to the Puerto Rico Medical Center. This study intended to develop more awareness of the risks of spinal cord injury after diving.

Methods: The patient's records for diving accident cases referred to our center during January 2014 until December 2020 were assessed retrospectively.

Temporal Evolution of Hypertrophic Olivary Degeneration in a Pediatric Patient: A Case Report and Review of Literature.

Hypertrophic olivary degeneration (HOD) is a rare type of neuronal degeneration seen after interruption of the dentato-rubro-olivary tract also known as the Guillain-Mollaret triangle (GMT). It is associated with hypertrophic changes of the inferior olive. Commonly reported in adults, this lesion presents with ataxia and oculopalatal myoclonus.

Posttraumatic Hydrocephalus in Pediatric Patients After Decompressive Craniectomy.

Objective: The risk for developing posttraumatic hydrocephalus (PTH) is higher when patients undergo decompressive craniectomy as part of their treatment. The purpose of this study is to determine the prevalence of PTH after decompressive craniectomy in pediatric patients and determine associated risk factors that may lead to PTH.

Methods: A retrospective analysis was conducted by searching the Puerto Rico neurologic surgery database from 2010 to 2019.

Obstructive Hydrocephalus and Chemical Meningitis Secondary to a Ruptured Spinal Epidermoid Cyst.

Background: Epidermoid cysts of the spinal cord may rupture, resulting in keratin dissemination in the subarachnoid space, in the ventricles, and along the central canal of the spinal cord causing meningitis, myelopathic changes, or hydrocephalus.

Case Description: A 53-year-old woman with no past medical history presented with a 2-week history of headache located in the occipital region associated with neck pain. Brain magnetic resonance imaging demonstrated multiple fat droplets scattered throughout the subarachnoid and intraventricular spaces with significant edema of the right posterior temporoparietal lobes with trapping of the right temporal horn of the lateral ventricle and atrium.
