“…Despite their rare occurrence and benign character, colloid cysts are of great clinical significance as they can cause acute deterioration and sudden death due to their critical location [ 7 – 11 ]. On the one hand, acute decompensation can result from acute severe increase in ICP due to intracystic hemorrhage or acute obstruction of the foramen of Monro and in the absence of immediate surgical intervention, brain herniation.…”

“…On the one hand, acute decompensation can result from acute severe increase in ICP due to intracystic hemorrhage or acute obstruction of the foramen of Monro and in the absence of immediate surgical intervention, brain herniation. On the other hand, acute decompensation was also found to occur without significant hydrocephalus due to compression of the hypothalamus, which in the absence of immediate surgical intervention can lead to autonomic dysfunction causing sudden cardiac failure [ 11 , 16 ].…”

“…Most colloid cysts are found incidentally on brain imaging and are asymptomatic. CCs tend to slowly increase in size over time, and although most may never reach a size that will cause any problem, some may grow more quickly and become symptomatic, even lead to sudden death due to causing acute hydrocephalus, raised intracranial pressure (ICP), or hypothalamic stimulation [ 7 – 11 ]. Obstructive hydrocephalus is precipitated by blockage of cerebrospinal fluid (CSF) outflow from the lateral ventricles at the foramen of Monro [ 3 , 12 ].…”

Acute hydrocephalus caused by a colloid cyst — a case report

Background Colloid cysts are rare benign, slowly growing intracranial tumors of endodermal origin. Most colloid cysts are found incidentally and are asymptomatic, but rarely, they can lead to sudden death. Case presentation A 73-year-old female patient was admitted to our emergency department with complaints of dizziness, nausea, vomiting, fatigue, walking difficulties, and behavioral changes. CT imaging revealed acute obstructive hydrocephalus attributable to a third ventricular colloid cyst. The patient was immediately transferred to a tertiary center where she underwent successful neurosurgical resection of the mass. Pathology results of the lesion confirmed the diagnosis of colloid cyst. Conclusion The case we present emphasizes the critical importance of prompt identification of warning signs, complex thinking, and evaluation. Establishing the right diagnostic approach early on can facilitate accurate diagnosis.

“…A case series of 65 patients suggests that symptoms associated with sudden death in patients with colloid cysts include sudden severe headaches and vomiting [ 8 ]. Other features that were noted to be associated with sudden death include larger cysts >1 cm and associated hemorrhage, as well as radiographic evidence of ventriculomegaly [ 8 ]. The neurosurgeons placed an external ventricular drain in this patient because of the relatively large size of her cyst.…”

Delayed hydrocephalus after excision of a colloid cyst: a case report

Background In this case report we describe an unusual case of a patient who underwent resection of a colloid cyst and then presented 6 weeks postoperatively with obstructive hydrocephalus. There appear to be no prior reports of such a delayed complication after colloid cyst resection. Case presentation A 50-year-old Caucasian woman underwent resection of a colloid cyst with an uncomplicated perioperative course. Postoperative imaging demonstrated complete resection of the cyst. She was discharged home on postoperative day 4 but presented 6 weeks later with symptoms of obstructive hydrocephalus resulting in poor neurologic outcome and ultimately death. Conclusion Patients presenting with symptoms of hydrocephalus after resection of a colloid cyst should be followed closely, and timely placement of an external ventricular drain may be critical.

“…Colloid cysts are rare and slow-growing benign lesions, most frequently located in the anterior part of the third ventricle. Due to the increased risk of acute obstructive hydrocephalus, or the development of chronic hydrocephalusrelated symptoms (i.e., headache, gait disturbance, and cognitive impairment), surgical excision of these lesions is required in symptomatic cases (1)(2)(3). The standard surgical procedures include transcortical, transcallosal, or endoscopic surgical approaches (4).…”

Structural Brain Network Reorganization Following Anterior Callosotomy for Colloid Cysts: Connectometry and Graph Analysis Results

Introduction:The plasticity of the neural circuits after injuries has been extensively investigated over the last decades. Transcallosal microsurgery for lesions affecting the third ventricle offers an interesting opportunity to investigate the whole-brain white matter reorganization occurring after a selective resection of the genu of the corpus callosum (CC).MethodDiffusion MRI (dMRI) data and neuropsychological testing were collected pre- and postoperatively in six patients with colloid cysts, surgically treated with a transcallosal-transgenual approach. Longitudinal connectometry analysis on dMRI data and graph analysis on structural connectivity matrix were implemented to analyze how white matter pathways and structural network topology reorganize after surgery.ResultsAlthough a significant worsening in cognitive functions (e.g., executive and memory functioning) at early postoperative, a recovery to the preoperative status was observed at 6 months. Connectometry analysis, beyond the decrease of quantitative anisotropy (QA) near the resection cavity, showed an increase of QA in the body and forceps major CC subregions, as well as in the left intra-hemispheric corticocortical associative fibers. Accordingly, a reorganization of structural network topology was observed between centrality increasing in the left hemisphere nodes together with a rise in connectivity strength among mid and posterior CC subregions and cortical nodes.ConclusionA structural reorganization of intra- and inter-hemispheric connective fibers and structural network topology were observed following the resection of the genu of the CC. Beyond the postoperative transient cognitive impairment, it could be argued anterior CC resection does not preclude neural plasticity and may subserve the long-term postoperative cognitive recovery.
