Magnetic resonance imaging (MRI) has an excellent soft tissue contrast and appears well suited to evaluate both the mastoid and possible complications of mastoiditis.
What is mastoid tip?
The mastoid part of the temporal bone is the posterior (back) part of the temporal bone, one of the bones of the skull. Its rough surface gives attachment to various muscles (via tendons) and it has openings for blood vessels. From its borders, the mastoid part articulates with two other bones.

What is sclerosis of the mastoid air cells?
Sclerosis of mastoid air cells is actually present whenever here is a loss of ventilation or aeration in the mastoid air cells. That usually as an isolated phenomenon is no of much of significance. But we have to find out if there are any known causes of loss of ventilation of mastoid air cells.
What causes fluid in mastoid cells?
