BACKGROUND: Gastric bezoars are masses of indigestible material that accumulate in the stomach, causing nausea, abdominal pain, and vomiting. Persimmon bezoars (diospyrobezoars), which comprise tannins and fibers from persimmons, are relatively rare but may cause significant gastric complications, including gastric outlet obstruction or ileus. Although computed tomography (CT) is a useful imaging tool, diagnosing bezoars can be challenging because their density is similar to that of food debris and gastric content.
CASE SUMMARY: Here, we report the case of a 72-year-old woman with a persimmon bezoar that was diagnosed using serial CT imaging and confirmed by endoscopy. CT performed over several months revealed changes in the internal structure and density of the bezoar, suggesting progressive hardening. The patient had a history of a partial gastrectomy and excessive persimmon consumption, both of which are risk factors for bezoar formation. Endoscopic fragmentation of the bezoar successfully resolved symptoms.
CONCLUSION: Gastric bezoars, particularly persimmon bezoars, present diagnostic challenges because of their variable imaging characteristics. Serial CT can document temporal changes in bezoar density, potentially reflecting changes in hardness. Early diagnosis and endoscopic treatment are essential for effective management, particularly in patients with predisposing factors. This case underscores the importance of considering bezoars in the differential diagnosis of gastric masses, and highlights the value of CT for monitoring changes in bezoar characteristics over time.
