Abstract:
Sonography of a patient with acute upper abdominal pain demonstrated an encapsulated hyperechoic mass which indented the stomach. Fine-needle biopsy produced atypical cells; the diagnosis of nodular intra-abdominal panniculitis was made at surgery. Sonography probably has a role in the detection and follow-up of this benign lesion.
