  2. Calcar avis - Wikipedia

    en.wikipedia.org/wiki/Calcar_avis

    The calcar avis, previously known as the hippocampus minor, [1] is an involution of the wall of the lateral ventricle's posterior cornu produced by the calcarine fissure. [ 2 ] It is sometimes visible on ultrasonogram [ 3 ] and can resemble a clot .

  3. Choroid plexus papilloma - Wikipedia

    en.wikipedia.org/wiki/Choroid_plexus_papilloma

    With a median age upon diagnosis of 3.5 years, this lesion is often a disease of infancy. They often reside supratentorial in the lateral ventricles of infants (most commonly in the atrium). [4] The fourth ventricle in adults is the optimum location. [5] Adults rarely have it at the cerebellopontine angle. [4]

  4. Lateral ventricles - Wikipedia

    en.wikipedia.org/wiki/Lateral_ventricles

    Lateral ventricles and horns The lateral ventricles connected to the third ventricle by the interventricular foramina. Each lateral ventricle takes the form of an elongated curve, with an additional anterior-facing continuation emerging inferiorly from a point near the posterior end of the curve; the junction is known as the trigone of the lateral ventricle.

  5. Central neurocytoma - Wikipedia

    en.wikipedia.org/wiki/Central_neurocytoma

    Central neurocytoma (CNC) is an extremely rare, ordinarily benign intraventricular brain tumour that typically forms from the neuronal cells of the septum pellucidum. [1] The majority of central neurocytomas grow inwards into the ventricular system forming interventricular neurocytomas.

  6. Colpocephaly - Wikipedia

    en.wikipedia.org/wiki/Colpocephaly

    Colpocephaly is a cephalic disorder involving the disproportionate enlargement of the occipital horns of the lateral ventricles and is usually diagnosed early after birth due to seizures. It is a nonspecific finding and is associated with multiple neurological syndromes , including agenesis of the corpus callosum , Chiari malformation ...

  7. Cavum veli interpositi - Wikipedia

    en.wikipedia.org/wiki/Cavum_veli_interpositi

    Axial MR/CT show a triangular-shaped cerebrospinal fluid (CSF) space between the lateral ventricles. On sagittal images, CVI can appear as a slit-like, linear-to-round/ovoid CSF collection below the fornices, and above the 3rd ventricle. There are usually no associated abnormalities, although larger lesions may cause an obstructive ...

  8. Periventricular leukomalacia - Wikipedia

    en.wikipedia.org/wiki/Periventricular_leukomalacia

    Periventricular leukomalacia (PVL) is a form of white-matter brain injury, characterized by the necrosis (more often coagulation) of white matter near the lateral ventricles. [ 1 ] [ 2 ] It can affect newborns and (less commonly) fetuses; premature infants are at the greatest risk of neonatal encephalopathy which may lead to this condition.

  9. Medical ultrasound - Wikipedia

    en.wikipedia.org/wiki/Medical_ultrasound

    Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
