Computed tomography findings in gastrointestinal involvement by opportunistic organisms in acquired immune deficiency
Abstract:
The computed tomography findings in two cases of gastrointestinal superinfection by opportunistic organisms in acquired immune deficiency syndrome are presented. Findings included thickening of the mucosal folds and the bowel wall in the small intestine and colon associated with cytomegalovirus and cryptosporidiosis. These cases indicate that it is important to look carefully at the gastrointestinal tract when performing computed tomography in this group of patients. Unsuspected bowel pathology may be demonstrated, or disease may be confirmed in clinically suspected cases.
Insights
Computed tomography reveals gastrointestinal superinfections in acquired immune deficiency syndrome patients. Opportunistic infections like cytomegalovirus and cryptosporidiosis cause bowel wall thickening, requiring careful CT evaluation.
Area of Science:
- Radiology
- Infectious Diseases
- Gastroenterology
Background:
- Acquired immune deficiency syndrome (AIDS) predisposes individuals to opportunistic infections.
- Gastrointestinal (GI) involvement is common in advanced HIV/AIDS.
- Accurate imaging is crucial for diagnosing GI complications in immunocompromised patients.
Observation:
- Two cases of AIDS patients with gastrointestinal superinfections were analyzed.
- Computed tomography (CT) was used to visualize the GI tract.
- Specific CT findings were correlated with identified opportunistic pathogens.
Findings:
- CT demonstrated significant thickening of the mucosal folds and bowel wall in both the small and large intestines.
- These findings were associated with cytomegalovirus (CMV) and cryptosporidiosis.
- The imaging findings highlighted the presence of superinfection by opportunistic organisms.
Implications:
- Careful examination of the GI tract during CT is essential for patients with AIDS.
- CT can reveal unsuspected bowel pathology in this vulnerable population.
- Imaging findings can confirm suspected GI disease, guiding clinical management.
