What condition is characterized by a collection of pus in the mastoid process?

• A. Mastoiditis
• B. Otitis media
• C. Chronic sinusitis
• D. Tympanic membrane perforation

Answer: (A)

Mastoiditis is characterized by the presence of a collection of pus in the mastoid process, which is the bony structure located behind the ear. This condition typically arises as a complication of acute otitis media, where an infection spreads from the middle ear to the mastoid air cells. The symptoms of mastoiditis can include pain and swelling behind the ear, fever, and drainage from the ear, resulting from the infection accumulating in the mastoid process. The anatomy of the mastoid process allows for communication with the middle ear, making it susceptible to infections stemming from otitis media. The pus formation in the mastoid cells can lead to serious complications if not treated promptly, including hearing loss or intracranial infections. In contrasting conditions such as otitis media, chronic sinusitis, and tympanic membrane perforation, although they might involve ear problems or infections, they do not specifically refer to pus accumulation in the mastoid process itself. Thus, mastoiditis is the accurate answer reflecting the condition described in the question.
