Journal of Applied Biology & Biotechnology. 2024 Jul; 11(3): 87-892319-1090https://imsear.searo.who.int/handle/123456789/240876Background: Dengue fever is a syndrome caused by several arthropod-borne viruses, characterized by fever, myalgia or arthralgia, rash & thrombocytopenia. Various bleeding manifestations of dengue have been documented including petechiae, mucosal bleeding, pulmonary, GI, and cerebral hemorrhage. Abdominal hematoma presenting as acute abdominal pain is a rare complication of dengue fever and is frequently overlooked. There is a paucity of data in the current literature on such cases. Clinical Description: A 13-year-old male was admitted with a complaint of fever for 3 days and myalgia. The patient had hepatosplenomegaly and managed as dengue with warning signs with positive NS1 antigen and dengue IgM antibody Platelet count was 42×103/mm3. No history of any bleeding disorder, trauma, or exposure to anticoagulant drugs. On day 6 of admission, the patient developed acute pain in the right lumbar and inguinal region, along with a reduced ability to move the right leg. Hip joint movements on the right side were painful with no restriction. Management & Outcome: His coagulation profile was normal with a hemoglobin value of 10.5 g/dl and platelet count of 40×103/mm3. CECT abdomen- suggestive of retroperitoneal collection of fluid adjacent to right psoas muscle – consistent with retroperitoneal bleed.He was monitored, managed conservatively & showed gradual improvement. Platelet counts improved. Discharged at platelet count of 273×103/mm3 & when symptom-free.On follow-up after a month, he was asymptomatic. Conclusion: The possibility of a retroperitoneal hematoma should be considered in a case of unexplained lower abdominal pain & hip arthralgia with dengue fever. A high index of clinical suspicion and awareness can detect such cases with needful management.CECTDengue feverHepatosplenomegalyJournal ArticleIndiaSchool of Medical Sciences and Research, Sharda Hospital, Sharda University, Gretaer Noida, Uttar Pradesh, IndiaSchool of Medical Sciences and Research, Sharda Hospital, Sharda University, Gretaer Noida, Uttar Pradesh, IndiaSchool of Medical Sciences and Research, Sharda Hospital, Sharda University, Gretaer Noida, Uttar Pradesh, IndiaSchool of Medical Sciences and Research, Sharda Hospital, Sharda University, Gretaer Noida, Uttar Pradesh, India
