Colloid Cyst – A Small Third Ventricle Cyst with Unusual Psammomatous Calcifications [PDF]

Journal of Clinical and Diagnostic Research, 2017
We report a case of a colloid cyst in the foramen of Monro, with an unusual finding of psammomatous calcifications. Colloid cysts of the third ventricle with calcifications in the wall are very rare.

Enterogenous Cyst and Glioblastoma: A Brief Histopathological Review of Two Uncommon Cystic Lesions of the Central Nervous System

Brazilian Neurosurgery, 2022
Intracranial cystic lesions are common findings in cerebral imaging and might represent a broad spectrum of conditions. These entities can be divided into nonneoplastic lesions, comprising Rathke cleft cyst, arachnoid cyst, and colloid cyst, as well as ...

Hemorrhagic Fourth Ventricle Colloid Cyst: A Report of an Unusual Presentation at an Uncommon Location

Indian Journal of Neurosurgery
Colloid cysts are benign cystic lesions characteristically arising from the third ventricle roof close to the foramen of Monro. Although incredibly rare, hemorrhage within a third ventricular colloid cyst is sparsely reported.

Hemorrhagic Colloid Cyst Presenting with Acute Hydrocephaly

Case Reports in Neurological Medicine, 2017
Colloid cysts are benign slow-growing cystic lesions located on the roof of the third ventricle that usually present with symptoms related to gradual rise of intracranial pressure.

Colloid cyst of third ventricle: Histopathological and ultrastructural study

Journal of Pathology of Nepal, 2019
Cysts occupying the third ventricle are rare lesions and may appear as an unusual cause of hydrocephalic crisis. A 40-year old woman with headache and one episode of fainting attack was diagnosed with a cystic lesion in the third ventricle after brain ...

Use of a neuro-evacuation device for the endoscopic removal of third ventricle colloid cysts

Frontiers in Surgery, 2023
BackgroundColloid cysts are benign tumors usually located at the level of the foramen of Monro and account for approximately 1% of all intracranial tumors. Endoscopic surgical treatment represents the approach of choice for removal of these tumors and is

Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

Advanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

Human Gut Bacteria and Lipidic Nanoparticles: Particle Composition Predicts Structural Transformation and Bacterial Biocompatibility

Advanced Functional Materials, EarlyView.
Lipidic nanoparticles (LNPs) were incubated with 21 gut bacteria frequently associated with the human microbiome. SAXS revealed that ∼75% of tested species induced structural transformations in monoolein LNPs, whereas phytantriol and phospholipid formulations remained unaffected.

Intrinsic Photoactive Star ZnPc–Poly(glutamate) Nanoplatforms for Multimodal Glioblastoma Therapy and Brain‐Targeted Delivery

Advanced Functional Materials, EarlyView.
An intrinsic photoactive star‐shaped zinc phtalocyanine‐poly(L‐glutamic acid) (ZnPc‐PGA) nanoplatform for multimodal glioblastoma (GBM) therapy and brain‐targeted elivery. A ZnPc‐PGA‐based multifunctional theranostic nanocarrier platform enables image‐guided, multimodal GBM therapy. ZnPc‐PGA nanocarriers support the integration of fluorescence imaging,

Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

Advanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...
