Subgaleal hematoma in a child, without skull fracture
Abstract:
The rare cases of subgaleal hematoma in childhood reported previously have all been related to head trauma. A case of apparently spontaneous subgaleal hematoma is reported which was associated with a qualitative platelet defect and not with trauma. Subgaleal hematoma must be differentiated from subgaleal infection and air from frontal sinusitis with bony erosion, and from an encephalocele or tumor erosion through the skull. Computed cranial tomography is useful in that differentiation. Most cases have been managed conservatively, but subgaleal tap may be indicated if there is severe headache or potential scalp necrosis.
Insights
A rare spontaneous subgaleal hematoma in a child was linked to a platelet defect, not trauma. This finding highlights the need to consider non-traumatic causes and platelet function in diagnosing subgaleal hematoma.
Area of Science:
- Pediatric Hematology
- Pediatric Neurology
- Emergency Medicine
Background:
- Subgaleal hematoma (SGH) is a rare condition in children, typically associated with significant head trauma.
- Differential diagnosis of SGH includes infection, air from sinusitis, encephalocele, and skull tumors.
Observation:
- This report details a unique case of subgaleal hematoma in a child that appeared spontaneously.
- The hematoma was not linked to any history of head trauma.
Findings:
- The spontaneous subgaleal hematoma was associated with a qualitative platelet defect.
- This suggests a potential link between platelet dysfunction and the development of SGH in the absence of trauma.
Implications:
- Clinicians should consider non-traumatic etiologies, such as platelet disorders, in the differential diagnosis of subgaleal hematoma in children.
- Computed cranial tomography (CCT) is a valuable tool for differentiating SGH from other potential causes.
- While conservative management is common, subgaleal aspiration may be necessary for severe symptoms or impending scalp necrosis.
