Spontaneous subgaleal hematoma in a patient with sickle cell disease: A case report and literature review

Recurrent Nontraumatic Subgaleal Hematomas in a Pediatric Patient With Sickle Cell Disease

Spontaneous subgaleal hematoma in pediatric patients with sickle cell disease (SCD) is a rare occurrence that can present with symptoms mimicking ischemic stroke, a known complication of SCD. However, unlike ischemic stroke, subgaleal hematoma is nonlethal and can be managed conservatively without major sequelae. Here, we present the case of an adolescent with SCD who presented with 2 episodes of subgaleal and epidural hematomas, 2 years apart. The latter episode occurred while on crizanlizumab, an anti-P-selectin antibody, approved for use in SCD in 2019 to reduce the number of acute pain crises. We demonstrate the diagnosis of subgaleal hematoma and outline steps to conservative management which were safe and did not lead to focal neurologic deficits.

Acute soft head syndrome in a teenager with sickle cell anemia: A case report

Key Clinical Message

Sickle cell disease (SCD) rarely presents with acute soft head syndrome (ASHS) often posing a diagnostic dilemma. Recovery is typically spontaneous, however, in the context of lack of awareness and limited brain imaging it could potentially lead to poor outcome.

Abstract

ASHS is a rare complication of SCD, invariably occurring near puberty with hitherto elusive pathogenic mechanisms. ASHS often resolves spontaneously on conservative management, however, lack of awareness in the context of limited access to brain imaging could pose diagnostic challenges resulting in inappropriate management and untoward outcome. We present a case of a teenager who presented with subtle symptoms for which the diagnosis of sickle cell anemia (SCA) was delayed until he developed ASHS. LTM was a 16 years old boy with a history of recurrent joints pain since the age of 6 years, with a family history of SCA, but had initial negative sickling test. He presented with episodes of multiple joints pain, unprovoked scalp and left orbital swelling, low-grade fever and mild headache without any evidence for bleeding diathesis. The diagnosis of SCA was confirmed by hemoglobin electrophoresis. Computed tomography (CT) scan of the head revealed subgaleal heamatoma (SGH) and intraorbital haematoma without intracranial hemorrhage (ICH). He was managed conservatively with analgesics and hydration together with antibiotics for associated sepsis with complete resolution of clinical symptoms within 2 weeks. This case represents a rare scenario for a relatively mild SCA phenotype presenting with ASHS whose diagnosis poses an enigma in the resource-limited contex. It is therefore, prudent to recognize ASHS to avoid judicious interventions which could potentially result in untoward clinical outcome.

Acute Soft Head Syndrome (Subgaleal Haematoma) with Periorbital Oedema as a Rare Presentation in Sickle Cell Disease

Background

Sickle cell disease is a genetic condition frequently found in Africa and the Arabian Peninsula. Uncommon complications include subgaleal haematoma (soft head syndrome) and periorbital oedema.

Case presentation

A 17-year-old male patient presented with body aches and progressive right parieto-temporal and frontal head swelling. Physical examination revealed puffiness of the right eye that progressed rapidly to reddish periorbital oedema sparing the extraocular muscle and pupil response to light. CT and MRI of the brain suggested multiple subgaleal haematomas (soft head syndrome) and right periorbital oedema.

Conclusion

Subgaleal haematoma (soft head syndrome) and periorbital oedema are uncommon complications of sickle cell disease. Management is conservative rather than surgical.

LEARNING POINTS

Subgaleal haematoma concurrently with periorbital oedema is a rare presentation of sickle cell disease.There are no guidelines on treatment, but the conditions in our patient resolved with conservative management.
