To describe imaging features suggestive of retrograde perineural spread in progressive facial palsy without known tumoral origin. Two reports of perineural infiltration by salivary malignant tumors were diagnosed on abnormal enhancement of the facial nerve associated with an abnormal nerve enlargement (1/2). These unsuspected tumors were located in parotid gland (1/2) and the sub-maxillary gland (1/2). ENT tumors (especially adenoid cystic carcinomas) should be carefully searched in case of perineural spread, as these tumors may be misdiagnosed due to their size, location and signal. Therefore, imaging studies of facial palsy should include temporal bone, skull base, parotid gland, submaxillary gland and sub cutaneous areas of the face. A sub-maxillary gland tumor should be searched in case of facial palsy associated with glossodynia.
描述在无已知肿瘤起源的进行性面神经麻痹中提示逆行性神经周围扩散的影像学特征。两份关于涎腺恶性肿瘤神经周围浸润的报告，是根据面神经异常强化伴神经增粗诊断的（2例中的1例）。这些未被怀疑的肿瘤分别位于腮腺（2例中的1例）和颌下腺（2例中的1例）。在出现神经周围扩散的情况下，应仔细排查耳鼻喉科肿瘤（尤其是腺样囊性癌），因为这些肿瘤可能因其大小、位置和信号而被误诊。因此，面神经麻痹的影像学检查应包括颞骨、颅底、腮腺、颌下腺和面部皮下区域。在伴有舌痛的面神经麻痹病例中，应排查颌下腺肿瘤。
