A Caucasian female in her late forties presented to the Emergency Department (ED) with headache, ataxia, and mental status changes. A CT brain demonstrated dilated lateral ventricles with transependymal edema. An MRI of the brain demonstrated marked obstructive hydrocephalus from an obstructing colloid cyst at the level of her Foramen of Monro. The patient was transferred to a tertiary care center for neurosurgical removal of the cyst. Three months later, the patient was doing well and had resumed all activities of daily living without any residual neurological deficits. The goal of this case report is to educate readers on this atypical presentation of hydrocephalus, its symptomatology, and management to allow physicians to be more comfortable in making treatment decisions.

Background: Colloid cysts (CCs) are benign lesions commonly located in the third ventricle, near the foramen of Monro. They constitute about 0.5%-1% of all intracranial tumors.

Objective: To examine recurrence rates in patients undergoing microsurgical excision of colloid cysts of the third ventricle with long-term serial clinical and imaging follow-up and to identify risk factors for cyst recurrence.

Methods: In this retrospective study, we analyzed a single-surgeon cohort of 84 patients who underwent microsurgical excision of a third ventricular colloid cyst between 1994 and 2018 and who were followed for at least 12 months after surgery. The primary outcome of interest was recurrence (asymptomatic and symptomatic).

Article Synopsis
  • Colloid cysts are rare tumors in the brain that can lead to severe complications like obstructive hydrocephalus, sometimes resulting in death despite being usually benign.
  • A case study of a 29-year-old woman showed that delayed diagnosis of her symptoms, including headaches and nausea, led to rapid deterioration after a colloid cyst was found obstructing the third ventricle.
  • This incident emphasizes the need for healthcare professionals to recognize symptoms early and manage such conditions effectively, as well as the necessity for further research to improve treatment methods.
