A novel presentation of diaphragmatic flutter in a patient with obstructive sleep apnea and recurrent cerebellar hemangioblastoma

We report a unique case of diaphragmatic flutter in a patient with obstructive sleep apnea who had no respiratory symptoms related to flutter and a history of recurrent cerebellar hemangioblastoma. The flutter was detected during a routine follow-up monitoring through the built-in software of the positive airway pressure device; the flow and pressure curves showed abnormal and curious oscillations. The ultrasound confirmed the diagnosis and ruled out other causes of abnormal diaphragmatic movements. This case report contributes to the scientific literature by presenting a novel case of diaphragmatic flutter associated with recurrent cerebellar hemangioblastoma. It also emphasizes the need for more research on the pathophysiology and treatment of this rare condition.
