Rapid Deterioration and Fatal Outcomes in Colloid Cyst-Induced Obstructive Hydrocephalus: A Case Report.

Introduction: Colloid cysts are rare intracranial tumors that can cause obstructive hydrocephalus, a potentially life-threatening condition. Despite being typically benign, they often present with insidious symptoms, leading to delayed diagnosis and catastrophic outcomes. Case Report: A 29-year-old woman presented with a two-month history of worsening headaches, nausea, and vomiting. Neuroimaging revealed a colloid cyst obstructing the third ventricle, resulting in hydrocephalus. Despite emergency placement of an external ventricular drain, the patient's neurological condition deteriorated rapidly, culminating in brain death. Conclusions: This case highlights the critical importance of the early diagnosis and aggressive management of colloid cyst-induced hydrocephalus. The rapid progression of symptoms and devastating outcomes underscore the need for increased awareness among healthcare providers. Given the high mortality associated with this condition, further research is warranted to identify predictive factors and develop effective treatment strategies. [ABSTRACT FROM AUTHOR]
