Pre- (a and c) and postoperative (b and d) MRI after aspiration and complete capsule resection. Postoperative imaging in (d) (red circle) was first interpreted as a possible remnant even though gross total resection was confirmed intraoperatively.

On the other hand, GTR, which includes the complete removal of the capsule, was performed on 3 patients (6.7%) [Figures 6 and 7].
Pre- (a and c) and postoperative (b and d) MRI of different patients submitted to aspiration of the cyst's content and coagulation of its capsule. In (b), there are signs of manipulation with no cyst remnants while in (d), the capsule remnants are visible but with no mucin content.

Statistical analysis of pre- and postoperative cyst volume and ventricular size. Surgery was statistically associated with cyst volume and ventricular size reduction (P<0.0001).

For the other 7%, no cyst remnant had a volume higher than 0.15 cm3 [Figure 8]. Preoperative mean Evans index was 0.35 and postoperative, 0.29 (max 0.45 min 0.3) [Figure 8].
Eight-year follow-up after aspiration and coagulation. Small and stable remnant. No hydrocephalus.

CC aspiration and coagulation alone for all patients. CCs rest were stable for non-GTR patients, all of them asymptomatic [Figure 9].
