Summary
Human dirofilariasis, a rare zoonotic infection caused by Dirofilaria repens worms, often presents as subcutaneous nodules. This case highlights imaging and histopathology in diagnosing this unusual condition in an 11-year-old boy with infraorbital swelling.
Area of Science:
- Zoonotic infections
- Parasitology
- Medical imaging
Background:
- Human dirofilariasis is an uncommon zoonotic infection caused by the nematode Dirofilaria repens.
- It typically manifests as subcutaneous nodules, often in orbital and periorbital areas, following mosquito bites.
Purpose of the Study:
- To present a case of human dirofilariasis in an 11-year-old boy with infraorbital swelling.
- To emphasize the role of imaging in diagnosing dirofilariasis, differentiating it from other conditions with similar presentations.
Main Methods:
- Clinical presentation of infraorbital swelling in an 11-year-old boy.
- Diagnostic imaging to evaluate the swelling.
- Postoperative histopathological examination for definitive diagnosis.
Main Results:
- Imaging played a crucial role in diagnosing the condition, suspected to be dirofilariasis.
- Postoperative histopathology confirmed the presence of Dirofilaria repens.
Conclusions:
- Dirofilariasis should be considered in the differential diagnosis of subcutaneous nodules, particularly in the orbital region.
- Imaging and histopathology are essential for accurate diagnosis of human dirofilariasis.
