Lymphogranuloma venereum (LGV) proctocolitis mimicking rectal lymphoma

Lymphogranuloma venereum is a sexually transmitted infection caused by serotypes L1-3 of and may present as hemorrhagic proctocolitis. The diagnosis of an active infection is difficult to establish, as confirmatory testing can be unreliable or unavailable. Imaging findings can be nonspecific and mimic malignancy or other chronic infectious and inflammatory disorders. In this report, we present a case of lymphogranuloma venereum proctocolitis and its computed tomography features to highlight the relevant imaging findings and importance of timely diagnosis.
