  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. 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.

  4. Septum pellucidum - Wikipedia

    en.wikipedia.org/wiki/Septum_pellucidum

    The lateral ventricles sit on either side of the septum. The septum pellucidum consists of two layers or laminae of both white and gray matter. [1] During fetal development, there is a space between the two laminae called the cave of septum pellucidum that, in ninety percent of cases, disappears during infancy.

  5. Transthoracic echocardiogram - Wikipedia

    en.wikipedia.org/wiki/Transthoracic_echocardiogram

    A transthoracic echocardiogram (TTE) is the most common type of echocardiogram, which is a still or moving image of the internal parts of the heart using ultrasound.In this case, the probe (or ultrasonic transducer) is placed on the chest or abdomen of the subject to get various views of the heart.

  6. Ventricular system - Wikipedia

    en.wikipedia.org/wiki/Ventricular_system

    The ventricles contained within the rhombencephalon become the fourth ventricle, and the ventricles contained within the mesencephalon become the aqueduct of Sylvius. Separating the anterior horns of the lateral ventricles is the septum pellucidum : a thin, triangular, vertical membrane which runs as a sheet from the corpus callosum down to the ...

  7. Neuroimaging - Wikipedia

    en.wikipedia.org/wiki/Neuroimaging

    X-ray images of the ventricular system within the brain were obtained by injection of filtered air directly into one or both lateral ventricles of the brain. Dandy also observed that air introduced into the subarachnoid space via lumbar spinal puncture could enter the cerebral ventricles and also demonstrate the cerebrospinal fluid compartments ...

  8. Cave of septum pellucidum - Wikipedia

    en.wikipedia.org/wiki/Cave_of_septum_pellucidum

    The septum pellucidum is a thin, laminated translucent vertical membrane in the midline of the brain separating the anterior horns of the right and left lateral ventricles. It lies posterior to the corpus callosum. Persistence of the cave of septum pellucidum after infancy has been loosely associated with neural maldevelopment and several ...

  9. 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 ...
