This case involved a forty five-year-old male who had significant, long-standing headaches consistent with a malignant brain tumor. The man visited his primary care doctor because of constant dull headaches he experienced. He had a positive family history of migraine headaches both in his father and brother. The family physician initiated him on a non-steroidal anti-inflammatory (NSAID) and scheduled him for a follow-up in two weeks. Upon follow-up, the patient expressed that he still experienced headaches which increased in severity since the last visit. Due to his family history, the doctor tried a trial of sumatriptan, under the suspicion that he was having migraine headaches. A follow-up appointment was never officially scheduled. Over the next month, the man stopped taking sumatriptan due to side effects and lack of efficacy. One day at home, the patient began to convulse, which caused him to drop to the floor. He was brought to the emergency department, where he was diagnosed with a brain tumor on an MRI. Biopsy of the tumor and further evaluation revealed a stage 3 glioblastoma, with metastases to the regional lymph nodes and right lung. He was then scheduled for stereotactic brain surgery, followed by chemotherapy. Nine months later, the patient stopped responding to treatment and died shortly thereafter.
