Trichobézoard gastrique révélé par une anémie chez une adolescente : association échographie - imagerie par résonance magnétique (IRM)

Giant trichobezoar of duodenojejunal flexure: A rare entity

“…[3] In some cases, abdominal x-ray can suggest the diagnosis by showing heterogeneous density, and abdominal ultrasound would confirm an intraluminal mass with a hyper-echoic arc-like surface and a marked acoustic shadow suggestive of a bezoar. [45] These examinations suggested the diagnosis in our patient, and performing CT scan did not seem necessary to us. In other reported cases, CT scan represented the examination of choice.…”

“…)[3] Like in our patient, clinical picture has no specification; trichobezoar may stay asymptomatic for a long time or may manifest as epigastric discomfort (80%), abdominal pain (70%), nausea and vomiting (65%), asthenia with weight loss (38%) or intestinal transit troubles like diarrhea or constipation (33%). [45] Sometimes, the bezoar manifests itself with gastrointestinal complications such as upper gastrointestinal hemorrhage due to ulcerations, mechanical gastric or small intestinal occlusion, gastric or small intestinal perforation with peritonitis or subphrenic abscess, digestive fistula, cholestasis or acute pancreatitis due to obstruction of the ampulla of Vater by the prolongation of the trichobezoar as in Rapunzel syndrome.

Giant gastroduodenal trichobezoar: A case report

“…Fortunately, ultrasound and CT provided the positive information for the diagnosis, especially combined with 3D reconstructed CT images. As a noninvasive and nonirradiated tool, MRI is also useful for detecting this entity, especially in the pediatric population[20]. More importantly, the history of mental disorder, the uncontrolled urge to pull out one’s hair and swallow it, is vital as a critical clue for making a clinical diagnosis.…”
