Acute mastoiditis is a commonly occurring condition in children and adults, and one that most radiologists will come across at some point during their on-call duties. Acute mastoiditis is usually clinically apparent. However, the complications, especially the intracranial ones, can be more insidious and may have fatal consequences. Therefore, it is imperative that the radiologist is well versed in identifying these. Local spread of infection from the mastoids and middle ear cleft may occur via four routes: bone erosion, thrombophlebitis, periphlebitis, and via the anatomical pathways. The role of radiology is largely to demonstrate the complications of mastoiditis, which can be clinically occult and are often serious; this article will highlight these complications.
急性乳突炎是儿童和成人中常见的疾病，大多数放射科医生在值班时都会遇到这种疾病。急性乳突炎通常在临床上很明显。然而，并发症，特别是颅内并发症，可能更为隐匿，可能导致致命后果。因此，放射科医生必须精通识别这些并发症。感染从乳突和中耳裂隙向远处扩散可通过四种途径：骨侵蚀、血栓性静脉炎、静脉周围炎和通过解剖途径。放射学的作用主要是显示乳突炎的并发症，这些并发症可能在临床上隐匿存在，且通常很严重；本文将重点介绍这些并发症。
