Management of pineal and colloid cysts

Abstract: The widespread use of MRI has led to the increasingly frequent diagnosis of pineal and colloid cysts. While most are small and incidental, do not require long-term monitoring and will never need treatment, they are a cause of patient anxiety and clinician uncertainty regarding the optimal management—particularly for larger cysts or those with an atypical appearance. Occasionally pineal cysts, and more commonly colloid cysts, cause hydrocephalus that requires urgent neurosurgical treatment. More recently the no… Show more

“…The prevalence of these lesions typically encompasses less than 2% of all intracranial tumors [ 1 ]. Colloid cysts have a collagen wall with a layer of epithelium filled with mucinous contents, generally called colloid, that can vary in color [ 1 , 2 ]. Typically, headache is the most common symptom associated with colloid cysts and occurs in about 60% to 90% of patients, and is typically related to CSF outflow obstruction at the foramen of Monro, resulting in hydrocephalus.…”

“…Radiologically, colloid cysts typically appear as well-demarcated cystic lesions at the foramen of Monro. Treatment for symptomatic colloid cysts requires surgical resection to prevent neurological deterioration [ 2 ]. Difficulty can arise as critical neurovascular structures such as the fornices and internal cerebral veins are typically near to colloid cysts.…”

“…Sometimes, neurosurgeons see patients with a wide range of complaints and a pineal cyst on MRI, which makes decisions about surgical or conservative therapy difficult (Jenkinson, Mills, Mallucci, & Santarius, 2021), (Kalani et al, 2015). Some reports, studies and meta-analyses have examined PC; however, the data on paediatric patients are scarce.…”

“…The most widely adopted management of patients with PCs is to first make sure that the cyst is non-neoplastic [33]. Management of SPCs with hydrocephalus is well-established [21]. Acute hydrocephalic SPC cases have traditionally been treated with shunts and more recently with endoscopic third ventriculostomy (ETV) with or without biopsy/ fenestration [21], although stereotactic aspiration, resection and conservative management have been used in some cases [2,16,32,36,45].…”
