Presentation
Vague abdominal pain.
Patient Data
Ultrasound of the abdomen showed a large midline cystic lesion causing bowel compression with no flow on color Doppler (not shown).
Contrast-enhanced CT scan of the abdomen using IV and oral contrast showed a large intramural filling defect within the 3rd and 4th parts of the duodenum and proximal jejunum, causing luminal attenuation. This filling defect showed lamellated/layering hyperdensity suggestive of hemorrhage.
Case Discussion
The appearance is very suggestive of intramural hematoma (for which the underlying cause in this particular cause is undetermined).
Follow-up ultrasound 1 month later (not shown) showed resolution of this filling defect.
