Diagnosed  2 mo. ago with 9mm calvarial hemangioma in right frontal skull within the diploic space. Now, I have sudden onset of painful lump on my forehead over the space where calvarial hemangioma was identified. What could this be? Is this cause for concern?
Hello and welcome to Chat Doctor, A swelling developing over the forehead needs to be investigated. A CT scan of the head needs to be done. A hematoma in the malarial bone can extend outside the bone and cause a forehead swelling. Surgical excision of the hematoma is the treatment of choice for hematoma. Thanks and take care Chat Doctor.
