Oligodendroglioma - Wikipedia
Classically they tend to have a vasculature of finely branching capillaries that may take on a "chicken wire" appearance. When invading grey matter structures such as cortex, the neoplastic oligodendrocytes tend to cluster around neurons exhibiting a phenomenon referred to as "perineuronal satellitosis".

Aug 28, 2023 · There is a network of thin blood vessels distributed throughout the tumor, described as a “chicken-wire” pattern in appearance. There are scattered calcifications and psammoma bodies within the tumor.

Jul 19, 2024 · Typically there is a delicate network of anastomosing capillaries giving it a so-called "chicken wire" appearance 6. These tumors are slowly growing. Grade 3 oligodendrogliomas (formerly known as anaplastic oligodendrogliomas) demonstrate increased cellular density, increased mitotic activity, microvascular proliferation and necrosis.
Oligodendroglioma: pathology, molecular mechanisms and markers
May 6, 2015 · The presence of a branching network of delicate capillaries (chicken-wire pattern) and extensive calcification are common, but not specific additional features in oligodendrogliomas. Rare oligodendroglial tumors show marked pleomorphism (‘polymorphic oligodendroglioma’) or cells arranged in a rhythmic/spongioblastic fashion.

Feb 22, 2016 · K trans can be estimated using MR steady-state dynamic contrast-enhanced perfusion imaging and is a combined measure of perfusion and capillary permeability. It assesses the leakage of contrast media through the vascular wall using T 1 weighted imaging.
Oligodendroglioma - Radiologica
Oligodendroglioma is a rare slow-growing adult-type diffuse glioma that arises from oligodendrocytes typically in the frontal lobes, characterised by 1p/19q codeletion, microscopic ‘fried egg’ cells with ‘chicken-wire’ capillary pattern on …
Oligodendroglioma - Libre Pathology
Acutely branched capillary sized vessels - "chicken-wire" like appearance. Abundant, delicate appearing; may vaguely resemble a paraganglioma at low power. Calcifications - important feature.

Dense network of acutely fine branched capillary sized vessels-classically referred to as a "chicken-wire" like appearance/pattern. Abundant and delicate appearing; may vaguely resemble a paraganglioma at low power. Small punctate calcifications, particularly along the blood vessels is a striking feature (but not a specific finding). Perifocal ...

Mar 26, 2024 · The “chicken wire” pattern of vessels is characteristic for oligodendroglioma . Dynamic susceptibility contrast (DSC) MRI has been the most studied vascular imaging technique for glioma [ 7 ], and normalized relative cerebral blood volume (nrCBV) is a semiquantitative measure derived from DSC that is widely used in clinical radiology.
