Ondine's curse syndrome primarily refers to cases with congenital central alveolar hypoventilation, but the term can also be used for acquired cases and implies central sleep apnea that occurs as a manifestation or complication of focal lesion in the area of the dorsolateral segment of medulla oblongata. It occurs rarely, but can lead to fatal outcome. Based on our own case report, the aim of this article is to review its clinical symptoms, and appropriate diagnostic and therapeutic procedures. We present a patient who had symptoms of vascular lesion of the dorsolateral segment of the medulla, which was verified by magnetic resonance imaging. On day 12 of his hospital stay, in the early morning, rapid development of coma was observed, which was an expression of serious respiratory failure with dominant hypercapnia. In the beginning, urgent intubation and mechanical ventilation were necessary, while in the later course of the disease breathing was assisted by noninvasive methods of Bilevel Positive Airway Pressure (BiPAP) and Continuous Positive Airway Pressure (CPAP). Throughout the night, polygraph recording confirmed the diagnosis of the central sleep apnea syndrome. The course of the disease was favorable, with a very slow but constant improvement of respiratory function. According to literature data, the disease course is not always favorable. There are published cases where it was concluded that ventilatory support was no longer needed but after a long period of normal breathing hypoventilation and death occurred suddenly during sleep. The treatment of central hypoventilation consists of ventilatory support, but there were also attempts of medicamentous treatment with the common aim of raising alertness and reactibility of the automatic breathing center. It is important to emphasize that patients with the risk of central sleep apnea should not be supplied with oxygen without arterial blood gas monitoring because of the possibility of delaying the right diagnosis. The use of oxygen in patients who already have hypercapnia due to hypoventilation could further intensify hyporeactivity of the breathing center and lead to respiratory arrest.

A case of the syndrome of the trephined progressing to paradoxical herniation is presented in a patient with a penetrating brain injury, postdecompressive craniectomy, and a delayed cerebral spinal fluid leak from a skull base defect. The patient had a penetrating head trauma from a high-velocity ballistic projectile during military wartime operations. The patient's clinical course, which demonstrates a rare presentation of central sleep apnea syndrome or Ondine's curse, is reviewed. Radiographic imaging includes sequential computed tomography (CT) scans with and without intrathecal contrast. Medical management was directed at increasing the intracranial pressures (ICPs) by placing the patient into Trendelenburg position and increasing hydration. Surgical intervention involved correction of the skull base defect by intranasal endoscopic repair. A literature review of paradoxical herniation and delayed neurologic decline in postcraniectomy patients is conducted, and the surgical and neurocritical care management is discussed.

Ondine's curse is an eponym that refers to central alveolar apnea/hypopnea observed among patients with acquired or congenital brainstem disorders. This condition results in loss of automatic and/or voluntary respiration with characteristic polysomnographic finding of impaired ventilator responses to hypercapnia and sleep apnea, which are more pronounced during non-REM sleep, less in REM sleep, and least during wakefulness.
