Abstract：
Components derived from an infected lesion within the bone can spread through various passages in the mandible, particularly via the mental foramen. Radiologically, the spread of infection is typically nonspecific and challenging to characterize; however, multislice computed tomography (MSCT) can effectively detect pathological changes in soft tissues and the bone marrow space. This report describes the case of a 55-year-old woman who experienced mental nerve paresthesia due to a periapical infection of the right mandibular second premolar. MSCT imaging revealed increased attenuation around the periapical lesion extending into the mandibular canal and loss of the juxtamental foraminal fat pad. Following endodontic treatment of the tooth suspected to be the source of the infection, the patient\'s symptoms resolved, and the previous MSCT imaging findings were no longer present. Increased bone marrow attenuation and obliteration of the fat plane in the buccal aspect of the mental foramen may serve as radiologic indicators of inflammation spreading from the bone marrow space.
摘要：
来自骨内感染病变的成分可以通过下颌骨的各种通道传播，特别是通过精神孔。放射学上,感染的传播通常是非特异性的，难以表征；然而，多层螺旋CT（MSCT）可以有效检测软组织和骨髓间隙的病理变化。本报告描述了一名55岁妇女的病例，该妇女因右下颌第二前磨牙的根尖周感染而出现精神神经感觉异常。MSCT成像显示，根尖周病变周围的衰减增加，延伸到下颌管，并丢失了近孔间孔脂肪垫。在对怀疑是感染源的牙齿进行牙髓治疗后，病人的症状得到缓解，以前的MSCT成像结果不再存在。精神孔颊侧的骨髓衰减和脂肪平面消失的增加可以作为炎症从骨髓间隙扩散的放射学指标。
