A 50-year-old woman with low grade fever presented to our emergency department. Computed tomography (CT) showed mediastinal and hilar lymphadenopathy. We diagnosed her with sarcoidosis based on uveitis, non-caseating pulmonary granulomas, gallium-67 scintigraphy findings, and bronchoalveolar lavage fluid findings. A month later, she presented with unilateral peripheral facial palsy and dysphagia. Magnetic resonance imaging revealed enhanced left facial and glossopharyngeal nerves. We diagnosed her with Heerfordt syndrome based on low grade fever, facial palsy, and parotid swelling. Facial palsy regressed completely and enhancement of cranial nerve on MRI also improved following corticosteroid treatment. So far, although facial palsy is the most frequent symptom in neurosarcoidosis, few reports that track changes in MRI images of the facial nerve have been reported. As described in a previous report, set up of MRI including slice thickness might be important in detecting cranial nerve involvement.
