Atypical Clinical Presentation of Crohn's Disease with Superior Mesenteric Vein Obstruction and Protein-losing Enteropathy

Polybacterial Iliopsoas Muscle Abscess as an Indication for Early Diagnosis of Crohn's Disease

BACKGROUND Crohn disease (CD) is a chronic, relapsing inflammatory bowel disease characterized by penetrations or fistulae in the gastrointestinal tract and abscesses in the surrounding tissues. Diagnosis of CD is difficult with an iliopsoas muscle abscess (IMA) as an initial presentation. CASE REPORT A 22-year-old Japanese man had right hip pain 17 days prior to admission. Because of worsening pain, he was admitted to our hospital. Physical examination revealed limitation of his right hip motion and a positive right psoas sign. Abdominal contrast-enhanced computed tomography (CT) revealed a large right IMA. Continuous drainage, which revealed polymicrobial pus, with intravenous administration of antibiotics dramatically decreased the size of the IMA. The drainage tube was removed on hospitalization day 9 because barium enema and contrast radiography of the abscess through the drainage tube showed no fistula. However, on day 19 of hospitalization, the IMA was redetected by abdominal CT. Continuous abscess drainage was resumed, and the third contrast radiograph of the abscess revealed contrast medium flow into the small intestine. Colonoscopy detected stenoses and circumferential ulceration of the terminal ileum. Histopathological examination of the ileum biopsy showed histocyte aggregation with lymphocyte or plasmacyte infiltration of the lamina propria, compatible with a CD diagnosis. Laparoscopic ileocecal resection was performed on day 64 of hospitalization. CONCLUSIONS Penetration of the intestinal tract caused by CD should be suspected in a patient with a polymicrobial IMA. It is essential to identify the fistula and subsequently perform surgical resection of the affected intestinal area.

Protein-losing enteropathy as precursor of inflammatory bowel disease: a review of the literature

We report the case of a 63-year-old female patient with liver cirrhosis who presented with symptoms of severe hypoalbuminaemia and diarrhoea. After ruling out other causes of hypoalbuminaemia and confirmation of an elevated faecal α-1 antitrypsin clearance, the diagnosis of protein-losing enteropathy (PLE) could be established. Since PLE is a syndrome caused by various diseases, classified into erosive and non-erosive gastrointestinal diseases or lymphatic obstruction, an extensive work-up was necessary, establishing the final diagnosis of Crohn's disease.

Protein-losing enteropathy as a complication of spontaneous isolated superior mesenteric artery dissection: A case report

INTRODUCTION

Protein-losing enteropathy and spontaneous isolated superior mesenteric artery dissection are both rare clinically. Protein-losing enteropathy due to superior mesenteric artery dissection is extremely rare.

PATIENT CONCERNS

A 46-year-old male with acute abdominal pain and hematochezia was diagnosed with a complete occlusion of the superior mesenteric artery because of dissection. He suffered from diarrhea and hypoproteinemia after an emergency thromboendarterectomy.

DIAGNOSES

Based on laboratory tests and capsule endoscopy inspection, a diagnosis of protein-losing enteropathy was made.

INTERVENTIONS

Endovascular treatment was provided.

OUTCOMES

After stent placement, he quickly recovered without a recurrence of symptoms.

CONCLUSION

Protein-losing enteropathy is a serious complication of an isolated superior mesenteric artery dissection. Restoring the patency of the superior mesenteric artery is keyed for the treatment of this complication.
