  Edited by ScholarGen MediAI Team Executive Answer Ménétrier disease is a rare protein-losing gastropathy characterized by markedly enlarged gastric rugal folds, typically involving the gastric body and fundus, with associated hypoalbuminemia and edema. In this 5-year-old boy, the combination of nausea, vomiting, intermittent abdominal pain, mild periorbital edema, severe hypoalbuminemia, and giant cerebriform gastric folds on contrast-enhanced CT and endoscopy strongly supports pediatric Ménétrier disease. Gastric biopsy demonstrated foveolar hyperplasia with glandular atrophy, while testing for Helicobacter pylori and viral inclusions was negative. Technetium-99m-labeled human serum albumin scintigraphy demonstrated gastrointestinal protein loss. The child improved with supportive treatment, with symptoms resolving four months after presentation. Why This Case Matters Pediatric Ménétrier disease is uncommon and can initially resemble a much more routine gastrointestinal illness...

  Edited by ScholsrGen MediAI Team Executive Answer A giant trichobezoar should be considered when a young patient presents with persistent upper abdominal pain, postprandial vomiting, abdominal distention, marked weight loss, and a palpable upper abdominal mass. On abdominal CT, the key clue is a large intraluminal gastric mass that is distinguishable from the gastric wall and may contain heterogeneous internal attenuation related to hair, air, and retained material. Upper gastrointestinal endoscopy can directly confirm the diagnosis. The critical imaging tasks are to define the extent of the bezoar, assess gastric outlet obstruction, determine whether it extends beyond the pylorus, and look for complications. A large trichobezoar may require mechanical or surgical removal, and evaluation for recurrent hair ingestion is important after treatment. Why This Case Matters A gastric mass on CT does not always represent a tumor. This distinction becomes particularly important when a pat...

 Edited by ScholarGen MediAI Team Executive Answer CHANTER syndrome is a clinical and neuroimaging syndrome described in patients with acute drug exposure and severe impairment of consciousness. Its characteristic imaging pattern centers on restricted diffusion and edema involving the cerebellum, hippocampi, and basal nuclei , often with additional cerebral white-matter involvement. The most important practical issue is not simply recognizing diffusion restriction. The radiologist must determine where the abnormalities are distributed, whether DWI abnormalities correspond to low ADC, and whether cerebellar edema is threatening the fourth ventricle and cerebrospinal-fluid pathways . This distinction matters because progressive cerebellar edema can produce fourth-ventricular obstruction, obstructive hydrocephalus, increased intracranial pressure, and potentially life-threatening neurologic deterioration. CHANTER should therefore be considered when severe altered consciousness after s...
