Background:
In our center, large vestibular schwannoma (VS) is typically managed by a planned partial resection through the translabyrinthine route. Here, we report on a rare complication of VS surgery and severe neurogenic pulmonary edema.
Case description:
A 33-year-old male was referred to our skull-base center with a large VS. A planned partial resection was performed. The surgery was without complications and the patient showed good recovery without facial nerve dysfunction. In the evening of the 2nd day after surgery, the patient showed rapid neurological deterioration, accompanied by cardiac arrest. After the patient was resuscitated, a computed tomography (CT) was made, which showed generalized (infra- and supratentorial) brain edema and hematoma in the resection cavity. Despite rapid removal of the hematoma, there was no change in the neurological situation. The next CT scan showed a further increase of brain edema and the patient died eventually. Autopsy revealed generalized lung edema, brain edema, and Hashimoto's thyroiditis. The pathologist diagnosed neurogenic lung edema.
Conclusion:
Neurogenic lung edema can occur on the 2nd day after surgery and induce rapid deterioration of the patient with massive brain edema.
