Fourteen months after resection of the mass, the patient was seen in the urgent care clinic for cough. Chest radiographs were normal and he was treated for bronchitis and released. Returning 1 month later, he observed that a "knot" had developed on his head after a blow to the parietal area. Physical examination showed an approximately 2-cm firm discoid nodule of the right occipitoparietal area. The "knot" was thought to be a calcified hematoma and the patient was told to seek follow-up care if the nodule changed. Four months later, he returned with complaint of a dry cough and variable headaches and incidentially requested an examination of the "knot" again. The scalp lesion had grown and was now boggy to palpation. All laboratory data was normal.Tuesday, 01 Feb 2005 13:47:46 GMT
