  • Spontaneous resolution of Colloid Cyst of the third ventricle: Implications for management
    Asian journal of neurosurgery, 2017
    Co-Authors: Mazda K Turel, Walter Kucharczyk, Fred Gentili
    Abstract:

    While there is little controversy regarding the treatment of symptomatic Colloid Cysts, the optimal management of "incidentally" detected and asymptomatic Colloid Cyst remains unclear. The age of the patient, duration and significance of symptoms related to the Cyst, size and radiological characteristics of the Cyst and the presence of hydrocephalus are all factors to be considered before considering surgery. While surgery most often provides good results in the majority of patients, complications do occur. Despite growing literature about the natural history of this condition, to date, only three cases of spontaneous resolution of Colloid Cyst

Despite growing literature about the natural history of this condition, to date, only three cases of spontaneous resolution of Colloid Cyst <10 mm have been reported. We report the case of spontaneous resolution of a Colloid Cyst larger than 10 mm, initially managed with close observation and serial neuroimaging. This case highlights the possible role for a conservative approach even in larger-sized Cysts.

  • Imaging of spontaneous intraventricular rupture of a septum pellucidum Colloid Cyst: case report
    Journal of neurosurgery, 2016
    Co-Authors: Harrison J. Westwick, Sami Obaid, Florence Morin-roy, Pierre-olivier Champagne, Alain Bouthillier
    Abstract:

    Intraventricular rupture of a Colloid Cyst is a rare phenomenon and has been proposed as a mechanism for sudden death in patients with Colloid Cysts. Imaging of a Colloid Cyst during rupture has been described in only one other instance. The authors report a highly unusual case of a 53-year-old man who presented with acute onset headaches and imaging findings of hydrocephalus caused by a Colloid Cyst originating from the septum pellucidum and superior surface of the roof of the third ventricle. Interestingly, the Colloid Cyst revealed imaging signs of intraventricular rupture characterized by a tail-like drainage of Cystic contents into the occipital horn of the lateral ventricle. The patient was surgically treated with a craniotomy and transcallosal approach to the Colloid Cyst, where it was noted that the Cyst wall was spontaneously open. This rare case highlights unique imaging findings of a rare event in an infrequent pathology confirmed with intraoperative microscopy. The authors further document the process of Cyst rupture and speculate on its pathomechanisms.

  • Colloid Cyst of velum interpositum a rare finding
    Journal of Neurosurgery, 2012
    Co-Authors: Thomas Morris, Stephen Santoreneos
    Abstract:

    The authors present the case of a child with a Colloid Cyst of the velum interpositum. To the best of the authors' knowledge, this is the first reported case in the pediatric literature and only the second reported case to date. The patient was of an 11-year-old boy in whom this lesion was found after a minor head injury. He had a 6-month history of memory deficits. A lesion consistent with a Colloid Cyst was seen in the region of the velum interpositum, in the roof of the third ventricle. This lesion was excised successfully via a transcallosal interfornical approach. There were no new postoperative deficits and the child made a full recovery of time.

  • remote transplantation of a third ventricle Colloid Cyst case report
    Journal of Neurosurgery, 2015
    Co-Authors: Samira Zabihyan, Hamid Etemadrezaie, Humain Baharvahdat, Aslan Baradaran, Babak Ganjeefar, Michael A Bohl, Peter Nakaji
    Abstract:

    The authors report the case of a 15-year-old girl with a third ventricle Colloid Cyst. She presented with prolonged headache, nausea, vomiting, and loss of visual acuity with bilateral papilledema. Computed tomography and MRI revealed severe biventricular hydrocephalus with transependymal periventricular fluid and a minimally enhancing Cystic mass of the third ventricle. The patient was diagnosed with a Colloid Cyst and obstructive hydrocephalus, and endoscopic resection with ablation of the Cyst remnant was performed. While attempting to extricate the Cyst from the patient's head, control of the Cyst was lost and the Cyst fell into the lateral ventricle beyond the surgeon's view. Postoperative imaging showed that the Cyst had settled in the right occipital horn. After 3 years of follow-up, imaging suggests growth of the Cyst in its new position without necrosis or displacement on prone imaging.

  • endoscopic approach to Colloid Cyst what is the optimal entry point and trajectory
    Journal of Neurosurgery, 2014
    Co-Authors: Leonardo Rangelcastilla, Fangxiang Chen, Lawrence Choi, Justin C Clark, Peter Nakaji
    Abstract:

    Object An optimal entry point and trajectory for endoscopic Colloid Cyst (ECC) resection helps to protect important neurovascular structures. There is a large discrepancy in the entry point and trajectory in the neuroendoscopic literature. Methods Trajectory views from MRI or CT scans used for cranial image guidance in 39 patients who had undergone ECC resection between July 2004 and July 2010 were retrospectively evaluated. A target point of the Colloid Cyst was extended out to the scalp through a trajectory carefully observed in a 3D model to ensure that important anatomical structures were not violated. The relation of the entry point to the midline and coronal sutures was established. Entry point and trajectory were correlated with the ventricular size. Results The optimal entry point was situated 42.3 ± 11.7 mm away from the sagittal suture, ranging from 19.1 to 66.9 mm (median 41.4 mm) and 46.9 ± 5.7 mm anterior to the coronal suture, ranging from 36.4 to 60.5 mm (median 45.9 mm). The distance from ...

  • Endoscopic Colloid Cyst resection in the absence of ventriculomegaly.
    Operative Neurosurgery, 2013
    Co-Authors: Scott D. Wait, Roberto Gazzeri, Adib A Abla, David A Wilson, Peter Nakaji
    Abstract:

    BACKGROUND: The absence of ventriculomegaly has been considered an overt or relative contraindication to the endoscopic resection of Colloid Cysts. In the past, endoscopic removal of Colloid Cysts in the absence of ventriculomegaly has been considered ill advised. Reports of successful endoscopic surgery in small ventricles are surfacing. OBJECTIVE: We examined the combined experience of 2 high-volume endoscopic centers to characterize the outcomes of patients undergoing endoscopic removal of Colloid Cysts in small ventricles. METHODS: We retrospectively reviewed all endoscopic Colloid Cyst removal procedures by the 2 senior authors (P.N., C.T.) performed at the Barrow Neurological Institute over an 8-year period. Radiographic, clinical, and interview data were recorded and analyzed. The age-adjusted relative bicaudate index was used to define small ventricles. RESULTS: Sixteen patients (8 female) underwent attempted endoscopic removal of a Colloid Cyst in the absence of ventriculomegaly. Surgery was technically successful in 15 patients. The Cyst was removed completely in 13 of patients. Short-term memory loss was initially present in 3 patients and completely resolved in all but 1 patient who had presented with short-term memory loss. Temporary complications occurred in 2 patients. CONCLUSION: Normal-size ventricles are not a contraindication to endoscopic removal of third ventricular Colloid Cysts. Complication rates are at least comparable to those of patients with ventriculomegaly or to those undergoing open microsurgical resection.
