BACKGROUND: Cytomegalovirus (CMV) is a common opportunistic pathogen in patients with HIV. It is also a major cause of gastrointestinal ulcers in patients with acquired immunodeficiency syndrome (AIDS). CMV pseudotumor in the stomach is a rare cause of digestive tract obstruction.
CASE REPORT: In this study we report a male patient infected with HIV in 2002. In 2014 he evolved C3 stage AIDS with pre-pyloric gastric ulcer which provoked deformity and pseudotumoral aspect of the gastric outlet. Endoscopic biopsy confirmed CMV infection. He underwent Roux-en-Y gastroenteroanastomosis with good recovery.
CONCLUSIONS: CMV infection should be considered as an agent in gastric lesions in HIV-infected patients. Roux-en-Y gastroenteroanastomosis is a surgical option for this group of patients, allowing improvements in quality of life and decreasing risks of perioperative complications.
