Background:
Surgical resection of symptomatic pineal cysts without hydrocephalus remains controversial because patients can present with variable symptoms. Hesitancies in surgical decision-making include determining surgical candidacy and whether results would be durable.
Methods:
We performed a retrospective analysis on patients who underwent resection of their pineal cysts in our practice. We examined the presenting symptomology and investigated the radiographic changes to the morphology of the cerebral aqueduct found on follow-up imaging. We examined the clinical outcomes and complications following surgical resection of symptomatic pineal cysts.
Results:
A total of 97 patients underwent resection of pineal cysts, with 84 patients who had adequate follow-up (mean: 30.5 months). The patient population were predominantly female (76%) presenting at a mean of 24 years of age. Almost half of the patients had headaches that were positional, with 82% being bilateral; 39% and 19% of patients presented with photophobia and sonophobia, respectively, concurrent with their headaches. Many patients presented with visual disturbance (73%) along with other non-headache symptoms. Surgery resulted in 89% of patients with clinical improvements of their headaches.
Conclusions:
Pineal cysts can present with variable headache symptomatology. Surgical resection of pineal cysts in carefully selected symptomatic patients after exhaustive conservative management can be performed safely and result in durable symptomatic relief.
