Delayed Massive Expansion of Subgaleal Hematoma Complicated with Proptosis in Hemophilia B

A Rare Case of a Subgaleal Hematoma With Global Developmental Delay, Scurvy, and Congenital Toxoplasmosis, Rubella, Cytomegalovirus, Herpes Simplex, and HIV (TORCH) Infection

This case report details the complex presentation of a six-year-old female child with global developmental delay (GDD), scurvy, congenital toxoplasmosis, rubella, cytomegalovirus, herpes simplex, and HIV (TORCH) infection and a subgaleal hematoma. The patient's medical history included delayed developmental milestones, bilateral congenital cataract, and a previous generalized tonic-clonic seizure. Thorough investigations revealed cerebral atrophy, bilateral ventricular dilatation, and periosteal thinning consistent with scurvy. The interdisciplinary approach involving neurology, ophthalmology, and orthopedics resolved the subgaleal hematoma. This case underscores the intricate interplay of neurological, nutritional, and infectious factors in pediatric conditions and highlights the importance of a collaborative, multidisciplinary approach for accurate diagnosis and effective management.

Massive subgaleal hematoma: a potentially fatal rare entity-a case-based review

BACKGROUND

Massive subgaleal hematoma is defined as profuse bleeding in the subgaleal layer of the scalp, causing excessive accumulation of hematoma, thus progressively increasing the size of head circumference. If not immediately diagnosed and managed carefully, continuous bleeding will lead to hematoma enlargement, impairing the functions of surrounding organ(s) and general homeostasis. In severe cases, subgaleal hematoma could lead to severe morbidity or even death.

CASE REPORT

We describe the case of an 11-year-old girl with a history of microcephaly and intellectual disability, presented with massive soft tissue swelling on more than half of her cranial circumference, accompanied with intermittent fever, anemia, and leukocytosis. The initial cerebral CT scan identified a mixed density extracranial lesion with multilobulated cystic appearance. The initial effort to aspirate the mass by a needle failed, and the patient was initially diagnosed with Pott's puffy tumor. Intraoperative findings confirmed the presence of massive subgaleal hematoma, and complete removal of the hematoma was achieved. The post-surgical period was uneventful, and the patient was discharged without any complications.

CONCLUSION

Massive subgaleal hematoma should be considered in cases where children's head circumference increases rapidly, with or without a clear history of trauma and the presence of any possible risk factors. Missed diagnosis and inappropriate therapy could lead to unfavorable outcome. Hence, it is important for any clinicians to be familiar with this entity, so timely diagnosis and treatment can be made.
