Purpose
Invasive aspergillosis (IA) represents a major cause of morbidity and mortality in immunocompromised patients. Involvement of the gastrointestinal tract by Aspergillus is mostly reported as part of a disseminated infection from a primary pulmonary site and only rarely as an isolated organ infection.
Methods
We report a case of small bowel perforation due to IA in a patient with acute leukemia under chemotherapy and pulmonary aspergillosis. We performed a systematic review of the literature as well.
Results
A 43-year-old man with acute myeloid leukemia under chemotherapy developed severe neutropenia and pulmonary aspergillosis due to Aspergillus flavus. He developed melena and hemodynamic failure and a contrast-enhanced ultrasound scan suggested active intestinal bleeding. During emergency laparotomy we found multiple intestinal abscesses, several perforations of intestinal loop and Aspergillus flavus was isolated from the abscesses. Resection of the jejunum was performed. The patient received voriconazole and finally recovered. The patient is now alive and in complete disease remission. From literature review we found 35 intestinal IA previously published in single case reports or small case series as well.
Conclusion
Clinical manifestations of gastrointestinal aspergillosis are nonspecific, such as abdominal pain, and only occasionally it presents as an acute abdomen. Antemortem detection of bowel involvement is rarely achieved and, only in cases of complicated gastrointestinal aspergillosis, the diagnosis is achieved thanks to the findings during surgery. Gastrointestinal aspergillosis should be suspected in patients with severe and prolonged neutropenia with or without pulmonary involvement in order to consider the right therapy and prompt surgery.
