Hiccoughs (singultus) are a complex physiological process characterized by sudden brief involuntary contractions of the diaphragm. They most commonly occur from peripheral mechanisms that result in diaphragmatic irritation, but also occur from brain stem lesions such as that seen in Wallenberg's syndrome. They are uncommon in sarcoidosis and it is remarkably rare when hiccoughs are the presenting symptom of neurosarcoidosis. We report a patient with sarcoidosis who presented with intractable hiccoughs due to an inflammatory medullary lesion. Evaluation revealed an enhancing lesion in the dorsomedial medulla that resolved after aggressive immune-modulating therapy. In the absence of a clear peripheral lesion that would potentially affect the diaphragm, the diagnosis of neurosarcoidosis involving the brainstem should be considered in patients with sarcoidosis.
呃逆(打嗝)是一种复杂的生理过程,其特征是膈肌突然短暂的无意识收缩。它们最常见于外周机制引起的膈肌刺激,但也发生于脑干病变,如 Wallenberg 综合征。在结节病中并不常见,而以呃逆为首发症状的神经结节病则非常罕见。我们报告了一例结节病患者,因炎症性延髓病变导致顽固性呃逆。评估显示背内侧延髓有增强病变,经积极免疫调节治疗后消退。在没有明确的可能影响膈肌的外周病变的情况下,对于结节病患者,应考虑累及脑干的神经结节病的诊断。
