Insights
Crimean-Congo hemorrhagic fever (CCHF) can present with abdominal pain mimicking appendicitis. This case highlights intramuscular hemorrhage as an unusual CCHF manifestation, requiring careful diagnosis.
Area of Science:
- Infectious Diseases
- Virology
- Clinical Medicine
Background:
- Crimeyan-Congo hemorrhagic fever virus (CCHFV) infection is a severe tick-borne viral illness.
- CCHF typically presents with fever, myalgia, and hemorrhagic manifestations.
- Abdominal pain can occur, but unusual presentations require thorough investigation.
Observation:
- A patient presented with symptoms including fever, malaise, headache, nausea, vomiting, diarrhea, and severe bleeding.
- Initial diagnosis suspected Crimean-Congo hemorrhagic fever virus infection, with ribavirin therapy initiated.
- During recovery, the patient developed acute right lower quadrant abdominal pain.
Findings:
- Exploratory laparotomy revealed intramuscular hemorrhage in the abdominal wall.
- Confirmation of Crimean-Congo hemorrhagic fever virus infection was established via positive CCHF IgM antibodies.
- This indicates an unusual manifestation of CCHF presenting as acute abdominal pain.
Implications:
- Highlights the diverse clinical spectrum of CCHF, extending beyond typical hemorrhagic symptoms.
- Emphasizes the importance of considering CCHF in patients with severe febrile illness and unusual abdominal presentations.
- Suggests that intramuscular hemorrhage should be recognized as a potential complication of CCHF, impacting surgical and diagnostic decisions.
Abstract:
An unusual cause of acute abdominal pain simulating acute appendicitis is presented. The patient was admitted with complaints of fever, malaise, headache, nausea, vomiting, diarrhoea, and severe bleeding. Based on the clinical and epidemiological findings, a diagnosis of Crimean Congo hemorrhagic fever virus infection was suspected, and ribavirin therapy was started. While her clinical condition was improving, she experienced a sudden pain at her right lower quadrant of the abdomen. Explorative laparotomy revealed haemorrhage within the abdominal muscles. Her CCHF IgM was found to be positive.
