Tricobezoar. Una causa rara de dolor abdominal con apariencia radiológica típica

A bezoar is a ball of swallowed foreign material that is usually vegetable fibers or hairs, in the digestive tract. Trichobezoars are rare and normally appear in individuals with mental disorders. We present the case of a 16 year old woman with emotional disorders who consulted due to abdominal pain, two-day long vomiting and mass in upper abdominal quadrant. A plain X-ray, ultrasonography and CT scan of the abdomen were performed. They showed typical X-ray signs of gastric trichobezoar. We emphasize the utility of the CT scan in the preoperative diagnosis and in he detection of possible complications. The patient was treated by laparatomy, gastrotomy and extraction of the trichobezoar. Postoperative period was without complications and she is currently receiving psychiatric treatment.
