Cranial masses in sickle cell disease

A 17-year-old African male with homozygous sickle cell disease was admitted with a vaso-occlusive crisis of the lower limbs and lower back, further complicated with an acute thoracic syndrome. After 6 days of treatment with intravenous fluids, analgesics and antibiotics, he developed holocranial headache, nausea and photophobia. Physical examination showed biparietal painful boggy masses (Figure 1). Neurological examination was unremarkable and there were no signs of intracranial hypertension. Skull ultrasound showed two heterogeneous fluid collections, compatible with subgaleal hematomas.
