We performed a retrospective chart review to categorize a group of petrous apex findings that were noted incidentally on magnetic resonance imaging (MRI) in 88 patients. These patients were among those who had been seen at a tertiary care center between July 1988 and July 1998. These incidental findings, which were unrelated to the presenting clinical manifestations, included asymmetric fatty bone marrow (n = 41), inflammation (19), cholesterol granulomas (14), cholesteatomas (9), and neoplasms (5). Followup imaging and clinical surveillance of these patients has not demonstrated any significant change in the incidentally detected lesions. In all cases, the incidental MRI findings represented benign pathology.
我们进行了一项回顾性病历审查，以对88例患者在磁共振成像（MRI）检查中偶然发现的一组岩尖病变进行分类。这些患者是1988年7月至1998年7月期间在一家三级医疗中心就诊的患者。这些与当前临床表现无关的偶然发现包括不对称性脂肪骨髓（n = 41）、炎症（19例）、胆固醇肉芽肿（14例）、胆脂瘤（9例）和肿瘤（5例）。对这些患者的随访影像学检查和临床监测未发现偶然发现的病变有任何显著变化。在所有病例中，MRI偶然发现均代表良性病变。
