Abstract

MR images of 35 adult and paediatric patients with clinical acute mastoiditis and 34 consecutive agematched controls without relevant middle ear pathology and with incidental T2hyperintensity that covered ≥ 50  of the mastoid were retrospectively analysed with regard to signal diffusion and enhancement characteristics and presence of complicationsIncidental mastoid T2hyperintensity that covered ≥ 50  of the mastoid volume was found in 46  of reviewed MR scans n = 2341 and associated significantly p  005 less with the involvement of the tympanic cavity 38  vs 74  and mastoid antrum 56  vs 80  hypointensetoCSF signal intensity on T2 FSE 6  vs 86  intramastoid diffusion restriction 0  vs 62  intense intramastoid enhancement 0  vs 51  periosteal enhancement 3  vs 69  perimastoid dural enhancement 3  vs 43  bone destruction 0  vs 49  intratemporal abscess or cholesteatoma 0  vs 24  labyrinth involvement 0  vs 14  and extracranial abscesses 0  vs 20
