Question

Patient with a history of chronic middle ear infection now presents with neurological manifestations, headache and vomiting. CT Brain is shown. What is the probable diagnosis?

• A. Extradural Abscess
• B. Cerebral Abscess
• C. Temporal lobe Abscess
• D. Meningitis

Answer 1

The Correct Option is C

In the given clinical scenario, the patient has a history of chronic middle ear infection and now presents with neurological manifestations such as headache and vomiting. This indicates a potential spread of infection from the middle ear to the brain.

The CT Brain would likely show a localized area of infection, and considering the proximity of the ear to the temporal lobe, this is the most probable site of an abscess formation. An abscess here would lead to increased intracranial pressure, which explains the headaches and vomiting.

Diagnosis: Temporal lobe Abscess.

Explanation: Chronic middle ear infections can lead to mastoiditis. If left untreated, the infection can spread to the adjacent temporal lobe of the brain, resulting in a localized abscess. This can present with symptoms like headache, vomiting, and other neurological deficits, depending on the area affected. The CT scan would show an area of hypodensity indicating the location of the abscess.
