A Pregnant Patient Presenting With Unilateral Sacroiliitis Following Dengue Hemorrhagic Fever: A Case Report.

Dengue virus infection is an arthropod-born infection with high global prevalence. A spectrum of clinical syndromes and complications were recognized following dengue fever that can range from undifferentiated fever to dengue shock syndrome. Neurological complications following dengue fever can extend to various sequelae, including transverse myelitis. We report a 20-year-old pregnant woman with a recent diagnosis of dengue hemorrhagic fever (DHF) at the period of amenorrhea (POA) of 28 weeks, presenting with left-sided severe buttock pain. Following extensive investigations, we found left-sided sacroiliitis to be the cause of the buttock pain. She completely recovered with appropriate management.
