Since the past 3 years, a 9-year-old boy was complaining of a continuous offensive discharge from his right ear . A month before admission to the clinic, the kid had begun to have vomiting, fever, and headache. He received symptomatic treatment for the symptoms. Since then, the condition of the kid was somewhat stable. However, after a couple of weeks, he started to suffer from a severe headache again along with drowsiness.
He also faced difficulty in climbing up and down the stairs. One week later, he developed weakness in the left arm and left leg, and became markedly drowsy. He became comatose the next day. What's your diagnosis? The correct answer is posted in the comment section below!
