Recently, there have been reports of false-positive HIV results associated with COVID-19 infections and vaccination, which require attention. The similarity between the spike proteins of HIV and SARS-CoV-2 may lead to cross-reactivity of antibodies, resulting in false-positive results on immunoassay screening tests. This hypothesis presents a serious diagnostic challenge. Patients presenting discordant COVID-19 and HIV results should undergo confirmation of the HIV chemiluminescent immunoassay due to the potential for analytical errors. It is essential to highlight the potential for false-positive HIV results related to SARS-CoV-2.

Intussusception is the invagination of a bowel segment into another immediately adjacent, causing obstruction, and the etiology can be benign, malignant, or idiopathic. The diagnosis may be obtained by ultrasound scans, or computed tomography imaging that can detect characteristics findings. Small bowel obstruction due to intussusception of inverted Meckel's diverticulum is a rare condition that usually constitutes a challenging diagnosis in adulthood. The surgical management in adults is often performed by en bloc resection without reduction attempts. We report a case of CASE REPORTS a middle-aged man with acute intestinal obstruction due to an ileo-ileal intussusception of inverted Meckel's diverticulum with a lipoma that was managed by laparoscopy. Worthy of note is the very scarce number of case reports on this exceeding uncommon association.
