Insights
A rare case of proptosis (eye bulging) occurred in a boy due to a subgaleal hematoma (SGH). Prompt intervention and diagnosis of hemophilia B were crucial for preserving vision.
Area of Science:
- Ophthalmology
- Pediatrics
- Hematology
Background:
- Subgaleal hematoma (SGH) is a rare collection of blood between the galea aponeurotica and the periosteum.
- Proptosis, or bulging of the eye, is an uncommon but serious complication of SGH, potentially leading to vision loss.
Observation:
- A 12-year-old boy developed proptosis after a scalp injury, with a rapidly expanding subgaleal hematoma.
- The proptosis resolved partially after emergent needle aspiration of the hematoma.
Findings:
- The patient was diagnosed with coagulation factor IX deficiency (hemophilia B).
- The supraorbital notch may serve as a pathway for SGH to extend into the orbit, causing proptosis.
Implications:
- This case highlights the importance of recognizing SGH as a potential cause of proptosis in pediatric patients.
- Early recognition and management of SGH, alongside hematological evaluation, are critical for preventing permanent visual impairment.
Abstract:
Proptosis after a subgaleal hematoma (SGH) is a rare condition that may require immediate intervention to prevent visual loss. A 12-year-old boy presented with localized SGH in the left parietal area after hair-pulling. The SGH was massively expanded on the entire scalp on the 3rd day of the trauma. On the next day after the massive expansion, proptosis of the right eye occurred suddenly. Emergent needle aspiration of the SGH was performed, and the proptosis improved slightly. Fortunately, his vision did not deteriorate. After all, he was diagnosed with coagulation factor IX deficiency (hemophilia B). The supraorbital notch could be a passage of the SGH to extend into the subperiosteal space of the orbit.
