Öncesinde Asemptomatik Olan Subdural Higroma İle Seyreden Spontan Araknoid Kist Rüptürü: Olgu Sunumu

Abstract

Aim: Spontaneous rupture of an arachnoid cyst resulting in a subdural hygroma is an infrequent event. We report an adult patient who had no previous neuroimaging and had acute onset headache, dizziness, and nausea unrelated to trauma.
 
 Case: A 67-year-old male patient was brought to the emergency service complaints of sudden onset of dizziness, headache, and vomiting while working in the garden. He described ongoing nausea and headache localized to the frontal region. Brain CT imaging was planned for the patient whose nausea and dizziness worsened while his symptomatic treatment continued. In the brain CT, a large hypodense extracerebral collection was detected in the area starting from the middle fossa in the right cerebral hemisphere and extending to the convexity level in the frontoparietal region. The patient was consulted in the neurosurgery unit. Surgical intervention was not considered, and the patient was admitted to the neurosurgery service for treatment. Due to the asymptomatic course in the service follow-ups, he was discharged with outpatient clinic control recommendations.
 
 Conclusion: This case illustrates the importance of recognizing the possibility of spontaneous rupture of an arachnoid cyst. This phenomenon should be considered as a differential diagnosis in patients without head trauma. Although it is rare, being aware of such a case is helpful in preventing possible bad outcomes.
