Colloid Cyst – A Benign Cyst of the Brain

Colloid cysts are benign, epithelium-lined cysts that arise from the anterior part of the third ventricle of the brain. As the name suggests, these cysts contain a gelatinous or mucinous aterial within. Wallman first reported colloid cysts in 1858, and the legendary neurosurgeon Sir Walter Dandy successfully resected the cyst in 1921. Most often, these cysts are asymptomatic unless they obstruct the cerebrospinal fluid (CSF) flow pathways, leading to hydrocephalus.

At Hannah Joseph Hospital, we specialize in diagnosing and treating rare conditions like colloid cysts with precision and care.

Overview and Prevalence

Colloid cysts are slow-growing benign cysts (tumors) that comprise less than 1% of intracranial tumors. The age at diagnosis is usually between 20 and 50 years. These cysts attribute some movement within the ventricles and present with intermittent raised intracranial tension. There is no genetic predisposition seen, although familial occurrences of colloid cysts have been reported.

Symptoms and Signs

Symptoms of colloid cysts can vary based on their size and location. At Hannah Joseph Hospital, we have observed the following common symptoms:

  1. Headache: 68% of patients present with headaches, typically worse in the morning and exacerbated by leaning the head forwards.
  2. Drop Attacks: Sudden weakness in the lower limbs associated with falls, without loss of consciousness.
  3. Gait Disturbances: Difficulty walking or maintaining balance.
  4. Short-term Memory Loss: Patients may experience difficulty recalling recent events.
  5. Behavioral Changes: Noticeable changes in personality or behavior.
  6. Nausea and Vomiting: Common due to increased intracranial pressure.
  7. Urinary Incontinence: In some cases, patients may lose control of their bladder.

In rare cases, sudden death has been reported due to the acute blockage of CSF pathways, leading to hydrocephalus and brain herniation.

Diagnosis

Diagnosis of colloid cysts typically involves imaging techniques. At Hannah Joseph Hospital, we use:

  • – CT Scan: This imaging technique helps visualize the cyst and any associated hydrocephalus.
  • – MRI: Provides detailed images of the brain’s structures and the cyst’s exact location.

Sometimes, colloid cysts are discovered incidentally when a patient undergoes a CT scan for head trauma or other reasons.

Treatment at Hannah Joseph Hospital

Observation: Small, asymptomatic colloid cysts without hydrocephalus can be left alone and followed up periodically. Regular monitoring ensures that any changes in size or symptoms are promptly addressed.

Surgical Intervention: For symptomatic patients, surgical excision of the cyst is necessary. This can be done through:

  • – Microsurgical Excision: A precise surgical technique to remove the cyst.
  • – Endoscopic Excision: A minimally invasive procedure using an endoscope to remove the cyst.

Stereotactic Aspiration: In some cases, the cyst can be aspirated using stereotactic techniques to relieve symptoms.

Ventriculoperitoneal Shunt: If the cyst causes significant hydrocephalus, a shunt may be placed to divert excess CSF to the abdominal cavity.

Prognosis

The prognosis for patients with colloid cysts is generally good, especially when treated surgically. At Hannah Joseph Hospital, our patients benefit from advanced surgical techniques and comprehensive post-operative care, leading to minimal chances of recurrence and excellent recovery outcomes.
