Colloid Cyst Removal (Endoscopic & Minimally Invasive)
A colloid cyst is a benign cyst that forms in the third ventricle, a fluid-filled space in the center of the brain. Although benign, it sits at the drainage point for cerebrospinal fluid and can block flow, causing hydrocephalus. Larger cysts carry a small but real risk of sudden deterioration, which is why treatment is recommended for many patients even when symptoms are mild.
Symptoms
- Positional headaches (worse when lying down or standing up)
- Memory difficulty
- Nausea, vomiting
- Sudden severe headache or fainting
How it is diagnosed
MRI and CT of the brain. Size, ventricular enlargement and cyst appearance guide the decision to treat.
Treatment options
Without surgery
Small cysts without ventricular enlargement may be monitored with periodic MRI.
Surgical options Dr. Daggubati offers
- Endoscopic removal through a dime-sized opening
- Minimally invasive tubular (port) approach for complete resection
Common questions
Is colloid cyst surgery a big operation?
It is brain surgery, but the approach is small — typically a single small incision hidden in the hair, with most patients home in one to two days.
Why is a benign cyst treated so seriously?
Because of where it sits. A colloid cyst can block the narrow channel that drains spinal fluid from the brain, and that blockage can come on suddenly. Cysts over about one centimeter, or those already enlarging the ventricles, are generally recommended for removal.
What is recovery like?
Most patients are home in one to two days after endoscopic or tubular removal, with mild headache for a week or two. Memory function usually returns to baseline. Follow-up MRI confirms complete removal.
Not sure this is you?
Bring your imaging and your story. A single visit usually clarifies what is going on and which options are realistic. Request an appointment or call (301) 718-9611.
