Dengue fever complicated with bilateral Psoas hematoma and superadded infection: A case report.

Dengue hemorrhagic fever (DHF) typically presents with various bleeding manifestations such as epistaxis, gum bleeding, and gastrointestinal bleeding. However, spontaneous large muscle hematoma formation is a rare complication. This case report discusses a patient with DHF who developed bilateral psoas muscle hematomas, a very uncommon presentation. The patient experienced acute abdominal pain and was diagnosed with psoas muscle hematomas complicated by bacterial infection. Conservative treatment, including fluid management, blood transfusions, and antibiotics, led to the patient's full recovery. This case highlights the importance of suspecting muscle hematomas in DHF patients who present with sudden abdominal or flank pain, especially in the context of dropping hemoglobin and platelet counts. Imaging techniques such as ultrasonography and CT scans are critical for diagnosis. Early diagnosis, close monitoring, and appropriate conservative management are essential for preventing serious outcomes. Prompt treatment of any secondary infections is crucial for patient recovery. This case report reminds clinicians to consider a rare complication.
