ABSTRACT
The trigeminal nerve is responsible for transmitting sensory information from the face, nasal and mouth cavities, and most of the scalp. Trigeminal neuralgia (TN) is a chronic facial pain disorder characterized by spontaneous paroxysmal pain throughout the distribution of the trigeminal nerve. This study investigated the morphological and morphometric variations of the foramen rotundum (FR) and its association with TN through a retrospective radiological analysis. A cohort of 97 participants from King Fahad University Hospital, Saudi Arabia, comprising 57 TN patients and 40 controls, underwent head CT scans for measurement and analysis. The study revealed significant differences in the FR morphology between TN patients and controls, particularly noting narrower FR measurements among TN individuals, especially in females. The right side demonstrated narrower FR dimensions, potentially correlating with the predominant side of pain in TN patients. While the presence of bony spurs was absent in all participants, variations in FR shape, size, and spatial positioning were observed and compared across genders and groups. These findings provide crucial insights into the potential anatomical factors contributing to TN, emphasizing the importance of understanding FR variations in clinical assessment and management of TN cases. Further research focusing on FR morphology and its clinical implications is recommended to enhance understanding and aid medical professionals in addressing TN-related concerns.
ABSTRACT
Intestinal obstruction is a rarely encountered complication in patients with ventriculoperitoneal (VP) shunt. The most common causes of bowel obstruction in this subset of patients include volvulus, formation of a spontaneous knot, and adhesions. Herein, we report a 21-year-old bedridden male with a history of congenital hydrocephalus on VP shunt, spina bifida, neurogenic bladder, and paraplegia who presented with a seven-day history of abdominal discomfort, distention, constipation, vomiting, and intolerance to oral intake. Abdominal x-ray showed dilated bowel loops. Computed tomography (CT) of the abdomen demonstrated a closed-loop bowel obstruction at the level of the sigmoid colon caused by the coiling of the VP shunt catheter. Diagnostic laparoscopy revealed the VP shunt tube coiling around a segment of the sigmoid colon with no signs of bands, ischemia, or perforation. Pulling and shortening of the tube was done. The procedure went uneventfully, and the patient was discharged home in stable condition. Maintaining a high index of suspicion for knotting the peritoneal catheter around the bowel is crucial when a patient on a VP shunt presents with a picture suggestive of intestinal obstruction. Early surgical intervention might be required to prevent further progression and complications.
