The majority of cases are diagnosed by findings of increased eosinophils on mucosal biopsies. We describe a rare type of eosinophilic gastroenteritis with eosinophilic infiltration involving only the muscularis propria layer. This elusive diagnosis was made after a full-thickness intestinal wall biopsy. This predominantly muscular type eosinophilic gastroenteritis can cause intestinal obstruction or perforation. Similar to the predominantly mucosal type eosinophilic gastroenteritis, this type of eosinophilic gastroenteritis responds to low-dose or topical corticosteroids.application/pdfenCreative Commons Attribution 4.0 Internationaladult gastroenterologyeosinophilic gastroenteritiseosinophilic gastroenteritis diagnosisfull-thickness biopsygastroenterology and endoscopymuscular type eosinophilic gastroenteritisDigestive DiseasesAutoimmune DiseaseOral and gastrointestinalArticle - Refereed2022-09-22https://doi.org/10.7759/cureus.187901310Grider, Douglas [0000-0002-6346-094X]348046562168-8184
