ABSTRACT A retrospective review of colloid cysts diagnosed from 1974 to 1986 emphasizes the presenting symptoms of these lesions, their surgical management, and the contribution of modern imaging techniques to their diagnosis and therapy. In this 12-year period, 84 patients (45 men and 39 women) had a colloid cyst diagnosed. The patients' mean age was 46 years (range, 7-82 years). Surgery was performed in 55 patients, 7 of whom had undergone prior surgery elsewhere. The surgical approaches used were transfrontal-transventricular, transcallosal, computer-assisted stereotactic aspiration and resection by stereotactic craniotomy, and shunting of cerebrospinal fluid without removal of the lesion. There was no operative mortality, but complications occurred in 15 patients (27%). Preoperative imaging showed hydrocephalus in 93% of the patients: severe in 43%, moderate in 36%, and mild in 14%. In the surgically treated group, the most common presenting symptoms were headache, change in mental status, ataxia, nausea and vomiting, visual disturbance, emotional lability/inappropriate affect, depersonalization, and hypersomnolence. Twenty-four patients for whom surgery was not recommended are being followed up closely. Most of these patients had normal ventricles. The symptoms in this group included headache, anxiety/nervousness, ataxia, memory impairment, visual disturbance, and seizures. Five autopsy cases of patients with colloid cysts were available during this period and were reviewed. Direct removal of colloid cysts can be accomplished with low morbidity and mortality, avoiding the frequent revisions and complications related to shunt procedures. There is a subgroup of colloid cysts that can be operated upon electively or followed up closely with serial imaging studies.

BACKGROUND : Colloid cysts are one of the rare brain tumours and are mostly located in the anterosuperior portion of the third ventricle, between the fornix and surround of Foramen of Monroe. OBJECTIVES: Ÿ 1.To review the demographic information & analyse clinical manifestations of patients presenting with colloid cyst of third ventricle. Ÿ 2.To analyze the advantages and disadvantages of various surgical approaches Ÿ 3.To assess the surgical outcome in colloid cyst patients operated by any method. MATERIALS AND METHODS: A retrospective study was performed on 16 patients who presented with a colloid cyst and underwent surgery at the Department of Neurosurgery, King George Hospital, Andhra Medical College between 2013-2018. They were evaluated based on clinical ndings and imaging features, surgical approaches used for resection and their outcomes. RESULTS: Sixteen cases of colloid cyst of the third ventricle were operated upon between 2013-2018. There were seven male and nine female patients with their ages varying between 9 and 62 years old. Nine patients were operated on by using a transcortical trans-ventricular approach, four using the anterior trans-callosal approach and, three patients by using an endoscopic approach. In all patients, complete excision of the lesions was achieved. CONCLUSION: Colloid cysts, though benign, present surgical challenges because of its deep midline location. Complete excision of the colloid cyst carries an excellent prognosis. Surgery is a safe and effective treatment option for this benign lesion.

✓ Two cases are reported of third ventricle masses that were clinically and radiographically indistinguishable from pure colloid cysts. A 21- and a 36-year-old man presented with 5-year and 10-day histories of headache, respectively. Magnetic resonance (MR) imaging revealed smooth, homogeneous masses in the anterior third ventricle that were iso- to hyperintense on T1-weighted MR images and hyperintense on T2-weighted images. There was little enhancement with intravenous contrast material. In both patients, craniotomies were performed and histopathological examination revealed xanthogranulomas of the choroid plexus with only microscopic foci of colloid cyst-like structures. These cases illustrate that xanthogranulomas of the third ventricle may clinically and radiologically mimic pure colloid cysts, that a range of MR imaging signals can be seen, and that craniotomy rather than stereotactic aspiration is the indicated treatment.

Introduction: Colloid cysts of the third ventricle are rare, histologically benign lesions that can be associated with obstructive hydrocephalus. Endoscopic removal developed as an alternative to microsurgical craniotomy as a less invasive surgical treatment. This review examines the endoscopic surgical experience for a consecutive series of patients with colloid cyst of the third ventricle. Methods: Patients with a diagnosis of “colloid cyst of the third ventricle” who were treated in Calgary between January 1994 and July 2014 were reviewed using a clinic database and registry. Results: 95 patients were identified. 30 patients without hydrocephalus underwent serial MRI and clinical observation with one patient developing hydrocephalus leading to surgical treatment. 65 patients underwent endoscopic treatment of their colloid cyst (male=34; female=31). The mean age at diagnosis was 45.5 years. 3 patients had been previously treated with other surgical approaches. All surgically treated patients had hydrocephalus and hydrocephalus resolved in all 65 patients. 1 patient sustained an injury to the internal capsule with transient hemiparesis. Mean followup was 8.2 years (range 0.1-19.3 years). 3 patients experienced colloid cyst recurrence treated with a second endoscopic removal. Conclusion: Endoscopic treatment of third ventricle colloid cysts can be performed with low risk as an alternative to microsurgical resection.

Abstract BACKGROUND Colloid cysts are challenging lesions to access. Various surgical approaches are utilized which all require brain retraction, creating focal pressure, local trauma, and potentially surgical morbidity. Recently, tubular retractors have been developed that reduce retraction pressure by distributing it radially. Such retractors may be beneficial in colloid cyst resection. OBJECTIVE To retrospectively review a single neurosurgeon's case series, as well as the literature, to determine the efficacy and safety profile of transtubular colloid cyst resections. We also aim to describe our operative technique for this approach. METHODS We conducted a retrospective review of colloid cyst resections using either ViewSite Brain Access System (Vycor Medical, Boca Raton, Florida) or BrainPath (NICO, Indianapolis, Indiana) tubular retractors performed by a single neurosurgeon from 2015 to 2017 (n = 10). A literature review was performed to find all published cases of transtubular colloid cyst resections. RESULTS Gross total resection was achieved in all patients. Early neurologic deficit rate was 10% (n = 1), and permanent neurologic deficit rate was 0%. There were no postoperative seizures or venous injuries. Average hospital stay was 2.0 d. There was no evidence of recurrence at average follow-up length of 13.6 mo. A literature review demonstrated nine studies (n = 77) with an overall complication rate of 7.8%. CONCLUSION Tubular retractors offer an attractive surgical corridor for colloid cyst resections, avoiding much of the morbidity of interhemispheric approaches, while minimizing damage to normal cortex. There were no permanent complications in our series of ten cases, and a literature review found a similarly benign safety profile.

Colloid cysts are benign, thin walled spherical neoplasms, composed of a collagenous capsule, underlying epithelium that arises from brain’s epidermal embryonic remnants and a viscous centre. They are shown to approximate 0.5% of all intracranial tumours with no recorded evidence of the petrous temporal bone involvement. Colloid cyst of the petrous temporal bone often presents with clinical symptoms of headache, hearing loss, facial palsy and imbalance/vertigo. Which is diagnosed on radiological and histological findings. Histologically, they are lined by ciliated cuboidal to pseudo stratified columnar epithelium resting on an eosinophilic basement membrane. Imaging Techniques are helpful in early diagnosis and preventing further complications. Here we will be discussing about a 24-year-old female, a known case of petrous apex osseous haemangioma presenting with unstable gait and tingling sensation on one side of face leading to an incidental finding of a colloid cyst on petrous temporal bone through histological examination.

✓ Stereotactic aspiration is a valuable surgical alternative for colloid cysts when used alone or in conjunction with microsurgical resection. Since 1981, the authors have performed computerized tomography (CT)-guided stereotactic aspiration as the initial procedure in 22 patients with colloid cysts; stereotactic aspiration alone was successful in 11 patients (50%). Of the 11 patients in whom aspiration failed, stereotactic endoscopic resection was attempted in three and was successful in one. Seven patients required a craniotomy and microsurgical removal of the cyst performed via a transcortical approach. The preoperative CT appearance in eight cases of a hypodense or isodense cyst correlated favorably with successful aspiration of the cyst in six patients. A hyperdense appearance on the preoperative CT scan in 14 cases was associated with subtotal aspiration in 13 patients; five required craniotomy for removal. Preoperative magnetic resonance (MR) imaging in eight patients provided excellent anatomical definition of the cyst and its relationship to other structures of the third ventricle, but it was not possible to correlate successful aspiration with cyst appearance on MR images with short or long relaxation time sequences. The authors' 9-year experience suggests that preoperative CT studies accurately determine size, predict viscosity, and help to define a group of colloid cyst patients for whom stereotactic cyst aspiration will likely be successful. Unsuccessful stereotactic aspiration was related to two features: the high viscosity of the intracystic colloid material (nine patients), or deviation of the cyst away from the aspiration needle due to small cyst volume (two patients). Because of its simplicity and low risk, stereotactic surgery can be offered to selected patients as the initial procedure of choice. Craniotomy can be reserved for those whose imaging studies predict failure or for those whose cyst cannot be aspirated.

OBJECTIVE Many colloid cyst patients present with obstructive hydrocephalus that resolves after resection of the cyst. However, a proportion of patients with these cysts will require cerebrospinal fluid shunting after tumor resection, despite resolution of the obstruction at the foramina of Monro. The goal of this study was to determine if colloid cyst size or preoperative ventricular volume predicted the need for postresection shunting. METHODS In a retrospective study design, ICD-9 codes 742.2 (colloid cyst) and 348.0 (brain cyst) were used to identify patients who had undergone resection of a colloid cyst at the University of Florida over the last 20 years. Preoperative imaging (CT or MRI) with a stereotactic software program developed at the University of Florida was used to measure volumes of the colloid cyst and the lateral ventricles. The relationships among ventricular volume, colloid cyst volume, and postoperative shunting were analyzed. RESULTS The number of patients included in the study was 67, and their mean age was 37.7 years. Forty percent of the patients were female. Overall, 49.2% of the patients had a transcallosal approach, 35.8% a transcortical approach, and 14.9% an endoscope-assisted surgery. Mean preoperative ventricular volume was 76.5 cc in patients who never received a ventriculoperitoneal shunt (VPS) and 98.1 cc in those who were eventually treated with a VPS (p = 0.305). Patients with a postoperative VPS had an initial mean colloid cyst volume of 1.8 cc compared with 0.9 cc in patients without a VPS postoperatively (p = 0.019). Patients with colloid cysts larger than 0.6 cc (1-cm diameter) had a 12.8 increased odds of needing a VPS postoperatively (95% CI 1.81–275). CONCLUSIONS Larger colloid cysts are associated with an increased need for postresection shunting independent of preoperative ventricular size. Prospective studies of patients with colloid cysts are necessary to further identify risks of permanent hydrocephalus.

AbstractBackgroundPrimary hyperparathyroidism is the third most common endocrine disorder for which surgical procedure called parathyroidectomy is the most effective treatment. Since the early 20th century, parathyroid surgery has improved extensively. With the advances in preoperative imaging and with understanding the causes of disease, new and minimally invasive surgical approaches overrode the standard bilateral exploratory operations. Directed parathyroidectomy is currently the standard technique for treatment of primary hyperparathyroidism worldwide.ConclusionsSurgery is the only definitive treatment of primary hyperparathyroidism. The most appropriate type of surgical procedure depends on the number and localization of the hyperactive parathyroid glands, availability of modern imaging techniques, limitation of each type of procedure and expertise.

BackgroundAround 25% of patients who had a stroke do not present with typical ‘face, arm, speech’ symptoms at onset, and are challenging for emergency medical services (EMS) to identify. The aim of this systematic review was to identify the characteristics of acute stroke presentations associated with inaccurate EMS identification (false negatives).MethodWe performed a systematic search of MEDLINE, EMBASE, CINAHL and PubMed from 1995 to August 2020 using key terms: stroke, EMS, paramedics, identification and assessment. Studies included: patients who had a stroke or patient records; ≥18 years; any stroke type; prehospital assessment undertaken by health professionals including paramedics or technicians; data reported on prehospital diagnostic accuracy and/or presenting symptoms. Data were extracted and study quality assessed by two researchers using the Quality Assessment of Diagnostic Accuracy Studies V.2 tool.ResultsOf 845 studies initially identified, 21 observational studies met the inclusion criteria. Of the 6934 stroke and Transient Ischaemic Attack patients included, there were 1774 (26%) false negative patients (range from 4 (2%) to 247 (52%)). Commonly documented symptoms in false negative cases were speech problems (n=107; 13%–28%), nausea/vomiting (n=94; 8%–38%), dizziness (n=86; 23%–27%), changes in mental status (n=51; 8%–25%) and visual disturbance/impairment (n=43; 13%–28%).ConclusionSpeech problems and posterior circulation symptoms were the most commonly documented symptoms among stroke presentations that were not correctly identified by EMS (false negatives). However, the addition of further symptoms to stroke screening tools requires valuation of subsequent sensitivity and specificity, training needs and possible overuse of high priority resources.
