Primary solitary malignant hemangioendothelioma of vertex: A rare calvarial tumor

摘要

A 43-year-old male noticed painful vertex swelling while combing hair 3 months prior to presentation to our clinic. The frequency and severity of pain increased to an extent to disturb his sleep. Neurological examination was normal. Neuroimaging revealed an intensively enhancing calvarial lesion in the midline and parasagittal location, with destruction of skull bone but without parenchymal abnormality [Figure la-c]. Plain X-ray and computed tomography (CT) of the chest and CT and positron emission tomography (PET) scan of the abdomen did not reveal any abnormality.
