title: Sonographic "gastric corona sign": diagnosis of gastric pneumatosis caused by a penetrating gastric ulcer.
abstract: We present a case of gastric pneumatosis associated with splenoportal venous gas caused by a giant penetrating gastric ulcer. On sonography, the gastric pneumatosis appeared as a circular hyperechoic band with distal reverberations due to gas collection in the gastric wall; we termed this appearance the "gastric corona sign. "Awareness of this sonographic sign may aid in the early diagnosis of gastric pneumatosis.
