Abstract

We present a rare case of petrous apicitis initiated by middle ear inflammation in a diabetic patient with multiple cranial neuropathies for early diagnosis of this potentially life-threatening condition. The lesion appeared as opacification of middle ear, petrous apex with aggressive bony destruction on CT and diffuse petrosal T(1) hypointensity with adjacent soft tissue propagation on MRI. Gallium-67 single-photon emission computed tomography (SPECT) scan also contributed to evaluate response to therapy.

摘要

我们报告了一例罕见的岩尖炎病例，该病例由一名患有多种颅神经病变的糖尿病患者的中耳炎症引发，旨在对这种可能危及生命的疾病进行早期诊断。病变在CT上表现为中耳、岩尖混浊，伴有侵袭性骨质破坏，在MRI上表现为岩骨T(1)低信号，伴有相邻软组织蔓延。镓-67单光子发射计算机断层扫描（SPECT）也有助于评估治疗反应。
