“…Prior reports found that cysts greater than 1 cm in maximum dimension are rare and are more likely to be symptomatic. 20,29,34,65,69 Fetell et al 19 reported on 53 patients with pineal cysts who presented for medical attention. In that series, 7 patients had associated hydrocephalus and cysts greater than 2 cm in anteroposterior diameter.…”

“…Other investigators evaluated pineal cyst prevalence on MR imaging without specifically examining the effect of age on prevalence. Lum et al 34 examined MR images from 1000 patients and found 14 pineal cysts (1.4%). Lee et al 33 evaluated MR imaging studies performed in 1000 patients and found 15 pineal cysts (1.5%).…”

“…6,19,52,59 There have been several prior attempts to analyze the prevalence of pineal cysts in patients undergoing intracranial imaging, with estimates ranging from 1.0% to 4.3%. 3,7,15,22,[33][34][35]40,51,61 In the largest series of pineal cysts in adults prior to our current study, Sawamura et al 59 evaluated MR images from 6023 patients and found 79 pineal cysts (prevalence of 1.3%). In an age-specific prevalence analysis, these authors found a decrease in the prevalence of pineal cysts on imaging in adults.…”

Object We reviewed our experience with pineal cysts to define the natural history and clinical relevance of this common intracranial finding. Methods The study population consisted of 48,417 consecutive patients who underwent brain MR imaging at a single institution over a 12-year interval and who were over 18 years of age at the time of imaging. Patient characteristics, including demographic data and other intracranial diagnoses, were collected from cases involving patients with a pineal cyst. We then identified all patients with pineal cysts who had been clinically evaluated at our institution and who had at least 6 months of clinical and imaging follow-up. All inclusion criteria for the natural history analysis were met in 151 patients. Results Pineal cysts measuring 5 mm or larger in greatest dimension were found in 478 patients (1.0%). Of these, 162 patients were male and 316 were female. On follow-up MR imaging of 151 patients with pineal cyst at a mean interval of 3.4 years from the initial study, 124 pineal cysts remained stable, 4 increased in size, and 23 decreased in size. Cysts that were larger at the time of initial diagnosis were more likely to decrease in size over the follow-up interval (p = 0.004). Patient sex, patient age at diagnosis, and the presence of septations within the cyst were not significantly associated with cyst change on follow-up. Conclusions Follow-up imaging and neurosurgical evaluation are not mandatory for adults with asymptomatic pineal cysts.

“…[12][13] Several retrospective studies of consecutive MR imaging scans showed that the prevalence of cysts ranges from 1.5% to 10.8%. [5][6]8,[14][15][16] Most studies were conducted in patients with neurologic symptoms suggestive of an intracranial pathologic condition. One study, conducted among healthy volunteers aged between 22 and 40 years (13 men and 14 women) and using the conventional spin-echo T1-weighted sequence, reported the prevalence of benign pineal cysts to be 7.4%.…”
