Intracranial Cysts: A Single-Institution Experience With 27 Surgically Managed Cases

Introduction Intracranial cysts (ICs) are rare pathologies that are often found incidentally during radiological examinations. They may appear in various brain regions and are categorized as normal, congenital, traumatic, or tumor-associated variants. ICs can be asymptomatic or cause symptoms, such as headaches, visual impairments, or seizures, depending on their size and location. Severe complications include obstructive hydrocephalus, loss of consciousness, and intracranial bleeding. Surgical excision is the most accepted type of management in most ICs. Objectives This study aimed to evaluate 27 surgically managed ICs in a tertiary hospital focusing on their clinical, radiological, histopathological, surgical outcomes, and prognosis to enhance understanding and management of these rare, benign cysts. Methodology This retrospective cohort study included 27 surgically managed ICs with pathological confirmation in King Abdulaziz Medical City, National Guard Health Affairs, Jeddah, Saudi Arabia, from May 2016 to May 2023. All extracranial and nonsurgically managed cysts have been excluded from this study. Data on demographics, clinical presentations, radiological features, surgical outcomes, and follow-up were retrospectively extracted and analyzed. MRI and CT scans were reviewed to determine cyst characteristics. Surgical outcomes and postoperative complications were recorded. Data were collected via Google Forms and analyzed using the JMP Pro software. Ethical approval was obtained from King Abdullah International Medical Research Center, Jeddah, Saudi Arabia. Results The study included 27 ICs: 11 (40.74%) colloid cysts, six (22.22%) epidermoid cysts, five (18.51%) adamantinomatous craniopharyngiomas, two (7.40%) neuroepithelial cysts, and one each of Rathke's cleft cyst (3.70%), xanthogranuloma (3.70%), and dermoid cyst (3.70%). All 27 cases were surgically managed (100.00%), with gross total resection achieved in 14 (51.85%) cases. Only 12 cases (44.44%) did not develop any surgical complications. Twenty-two cases (81.48%) experienced an improvement in the preoperative presenting symptoms. During the follow-up, only three cases (11.11%) had evidence of recurrence. Conclusion This study analyzed 27 ICs of various histopathological types. Each type showed distinct clinical and radiological features. Surgical management generally improved preoperative symptoms with low mortality and recurrence rates, although complications were common. Identifying specific radiological features is crucial for an accurate preoperative diagnosis and optimal surgical outcomes.
