Click 51 year old female with a posterior rectus sheath hernia. Initial presentation. FINDINGS: Axial multidetector CT stack of the abdomen with intravenous and oral contrast shows multiple dilated loops of small bowel consistent with a small bowel obstruction. In retrospect, these small bowel loops extend through a large defect in the posterior rectus sheath. TECHNIQUE: GE Lightspeed VCT. Axial CT, 654 mA, 120 kV, 5 mm axial mm slices, Oral contrast- Omnipaque 240 50 ml + 850 ml water, IV contrast- Isovue-370 100 ml

Click 51 year old female with a posterior rectus sheath hernia. Initial presentation. FINDINGS: Sagittal reconstruction CT stack of the abdomen and pelvis with intravenous and oral contrast shows multiple dilated loops of small bowel consistent with a small bowel obstruction. In retrospect, these small bowel loops extend through a large defect in the posterior rectus sheath. TECHNIQUE: GE Lightspeed VCT. CT sagittal reconstruction, 654 mA, 120 kV, 3 mm sagittal reconstructions, Oral contrast- Omnipaque 240 50 ml + 850 ml water, IV contrast- Isovue-370 100 ml

Click 51 year old female with a posterior rectus sheath hernia. Several months after initial presentation. FINDINGS: Axial multidetector CT stack of the abdomen with intravenous contrast only was read as normal. In retrospect, a large posterior rectus sheath defect contains multiple loops of small bowel although no small bowel obstruction is present. TECHNIQUE: GE Lightspeed VCT. Axial CT, 704 mA, 120 kV, 3 mm axial slices, Oral contrast- none, IV contrast- Isovue-370 100 ml.

Click 51 year old female with a posterior rectus sheath hernia. 2 months after second presentation. FINDINGS: Axial multidetector CT stack of the abdomen with intravenous and oral contrast shows multiple dilated loops of small bowel consistent with a small bowel obstruction. The small bowel loops herniate through a large defect in the posterior rectus sheath fascia and abut the anterior abdominal wall. TECHNIQUE: GE Lightspeed VCT. Axial CT, 654 mA, 120 kV, 3 mm axial slices, Oral contrast- Omnipaque 240 50 ml + 850 ml water, IV contrast- Isovue-370 100 ml.
