ABSTRACT
Our aim was to reduce motion artefact during radiographic angiography and MRI of the lower limbs. The legs were immobilized using a bead bag with a filtered closeable valve. Air was removed by suction and the bag moulded into a rigid restraint. The bead bag is an effective, well tolerated and easily used immobilization device that is suitable for use in radiological imaging.

External ear canal cholesteatoma (EECC) is rare in ear, nose and throat (ENT) practice. Two cases, one bilateral, are described. Computed tomography demonstrates the extent of bony involvement. Erosion of the external canal should not be overlooked when reviewing CT of the petrous bone in cases of discharge from the ear. EECC may necessitate surgery and delay in the diagnosis of EECC can result in progressive bony destruction.
