Spontaneous epidural haematoma in a paediatric patient with sickle cell disease.

Spontaneous epidural haematoma (SEDH) is a rare complication of sickle cell disease (SCD). To our knowledge, 38 cases of patients with SEDH associated with SCD have been reported in the literature. In this case report we describe the first Danish paediatric case with SCD and SEDH. The pathophysiology of this association is not fully understood, but skull bone infarction, haemopoietic marrow expansion or compromised blood flow due to hyper viscosity might contribute to this rare complication. In patients with SCD presenting with relevant symptoms, early imaging could be considered.

Brown tumor mimicking metastases-the late manifestation of hyperparathyroidism.
