“…In colloid cysts diagnosis both, MRI and CT, are useful. 11 After excluding physiologic and traumatic causes of anisocoria, other possible causes should be evaluated. Horner's syndrome, glaucoma, pharmacological agents, migraine, 2 Adie's pupil, eye trauma, eye surgery, 3 oculomotor nerve palsy, carotid artery aneurysm, trauma, brain tumors and lesions 4 are the most common pathologic causes of anisocoria.…”

ntroduction Anisocoria is a condition characterized by unequal pupils. There are two described types: physiologic and pathologic. Pathologic anisocoria is caused by interruption in reflex arc. Reason of anisocoria can be difficult to define due to variety of possible diseases that may be causing it. Aim Case presentation of anisocoria caused by congenital cystic lesions of the brain. Case Study 12-year-old girl after head trauma was admitted to the Emergency Department due to anisocoria noticed by family doctor. Patient had headache, sleepiness, dizziness and lacrimation. After looking at patients’ childhood photo it was stated, that anisocoria was present before the injury. In physical examination decreased mobility of left eyeball, left-sided ptosis and left-sided decreased reaction to the light (both, direct and consensual) were noted. Head CT scan was performed, which revealed bilateral cystic lesions in basal ganglia, thalamus and in mesencephalon. The biggest lesions were located in left thalamus – 29x15mm. Biopsy of the biggest cyst was performed. No neoplastic tissue was found. Final diagnosis was stated: diencephalic and mesencephalic polycyclic lesions of unknown origin. Surgical approach was departed and conservative treatment was applied (regular head MRI scans) Results and discussion Described case report was an example of diagnostic difficulties which can be caused by anisocoria. In this case pathologic anisocoria was caused by congenital cystic lesions of the brain that were detected in the age of 12. Conclusions Anisocoria can be a sign of many different pathologies, but also can be physiologic. If pathologic anisocoria is suspected, imaging diagnostics should always be performed.

“…26 Since the year 2000, a total of 94 pediatric CCs have been reported in the literature, including 63 males and 31 females. 6,[19][20][21][22][23][24][25][26][36][37][38][39] Age at presentation was 3-18 years (about 8.5% were younger than 10 years of age). Note that 7 cases (7.5%) were diagnosed incidentally in this earlier study (compared to the 20% incidental findings in our study).…”

“…They usually present with hydrocephalus but may also present incidentally. 6,[19][20][21][22][23][24][25][26] A few case reports describing deaths related to CCs have been published, even during childhood. [27][28][29][30][31][32][33] Thus, awareness about this rare pathology by the treating teams should be increased.…”

OBJECTIVE Colloid cysts (CCs) are rare at all ages, and particularly among children. The current literature on pediatric CC is limited, and often included in mixed adult/pediatric series. The goal of this multinational, multicenter study was to combine forces among centers and investigate the clinical course of pediatric CCs. METHODS A multinational, multicenter retrospective study was performed to attain a large sample size, focusing on CC diagnosis in patients younger than 18 years of age. Collected data included clinical presentation, radiological characteristics, treatment, and outcome. RESULTS One hundred thirty-four children with CCs were included. Patient age at diagnosis ranged from 2.4 to 18 years (mean 12.8 ± 3.4 years, median 13.2 years, interquartile range 10.3–15.4 years; 22% were < 10 years of age). Twenty-two cases (16%) were diagnosed incidentally, including 48% of those younger than 10 years of age. Most of the other patients had symptoms related to increased intracranial pressure and hydrocephalus. The average follow-up duration for the entire group was 49.5 ± 45.8 months. Fifty-nine patients were initially followed, of whom 28 were eventually operated on at a mean of 19 ± 32 months later due to cyst growth, increasing hydrocephalus, and/or new symptoms. There was a clear correlation between larger cysts and symptomatology, acuteness of symptoms, hydrocephalus, and need for surgery. Older age was also associated with the need for surgery. One hundred three children (77%) underwent cyst resection, 60% using a purely endoscopic approach. There was 1 death related to acute hydrocephalus at presentation. Ten percent of operated patients had some form of complication, and 7.7% of operated cases required a shunt at some point during follow-up. Functional outcome was good; however, the need for immediate surgery was associated with educational limitations. Twenty operated cases (20%) experienced a recurrence of their CC at a mean of 38 ± 46 months after the primary surgery. The CC recurrence rate was 24% following endoscopic resection and 15% following open resections (p = 0.28). CONCLUSIONS CCs may present in all pediatric age groups, although most that are symptomatic present after the age of 10 years. Incidentally discovered cysts should be closely followed, as many may grow, leading to hydrocephalus and other new symptoms. Presentation of CC may be acute and may cause life-threatening conditions related to hydrocephalus, necessitating urgent treatment. The outcome of treated children with CCs is favorable.

Background: Incomplete resection of neurenteric cysts (NCs) has been associated with increased recurrence rates in patients compared to complete resection (CR) and information on intracranial NCs appearance on diagnostic imaging is scarce. We sought to identify factors associated with CR and provide the largest up-to-date review of NCs appearances on various diagnostic images. Methods: Data from Medline, EMBASE, and Web of Science were extracted. Univariate and multivariate logistic regression models were used to analyze factors associated with CR. Results: A total of 120 publications reporting 162 original cases on posterior fossa NCs met the inclusion criteria for analysis. Eighty-nine (55.6%) of the patients were female, the mean (SD) age of the patients’ during operation was 34.3 (16.9) years, and CR was achieved in 98 (60%) of patients. Univariate analysis identified male sex as a statistically significant predictor for complete reaction (OR 2.13, 95% Cl 1.10–4.11, P = 0.02). The retrosigmoid approach (OR 1.89, 95% Cl 0.98–3.63, P = 0.06), far lateral approach (OR 0.46, 95% Cl 0.21–1.02, P = 0.06), and pediatric patient (OR 2.45, 95% Cl 0.94–6.56, P = 0.07) may be possible predictors for CR, however, they were not statistically significant. NCs are mainly hypodense on CT (32 [61.5%]), varied greatly in intensity on T1WI, hyperintense on T2WI magnetic resonance imaging (98 [67.1%]), and hyperintense on fluid-attenuated inversion recovery (17 [63.0%]). Conclusion: We recommend utilizing various diagnostic imaging tests to help reduce misdiagnoses when identifying intracranial NCs. For patient safety, CR should be achieved when possible, to reduce risk of additional operations due to recurrence.
