MRI demonstrating dependent restricted diffusion in the area of the right occipital horn
, which likely reflects the presence of purulent material.
Areas of subependymal calcification in relation to the right occipital horn
The CT scan organised by the ophthalmologist showed "a proencphalic dilatation of the occipital horn
of the left lateral ventricle with loss of cortex affecting the medial aspect of the occipital lobe" and was thought to be longstanding.
1.) The report indicated a long convoluted tubular density in the lateral ventricles, with a metallic density in the occipital horn
of the left lateral ventricle.
A tiny new lesion involving the posterior right thalamus and a slight increase in periventricular T2 signal adjacent to the atrium and occipital horn
of the left lateral ventricle appeared.
MRI of brain revealed (i) sub ependymal grey matter heterotopia along the occipital horn
and atrium of right lateral ventricle.
There are two short occipital horns
and three temporal horns on each side, of which the external horns are the shortest (Horowitz, 1955; Sherbrooke, 2003).
Because patients are usually scanned in the supine position, particularly important locations include the interpeduncular cistern, the occipital horns
of the lateral ventricles, the quadrigeminal plate cistern, and the dependent portions of the Sylvian fissures (Figure 1).
That report stated, inter alias "The lateral ventricles are enlarged, including the atria, occipital horns
* a CSF-filled cleft lined by grey matter extending from the subarachnoid space from the right parietal lobe region communicating with the trigone and occipital horns
of the right lateral ventricle
Axial T2 and FLAIR images showed dilated occipital horns
of both lateral ventricles.
Radiographic findings of dysgenesis or agenesis of the corpus callosum include absence of, or a malformed corpus callosum (Figure 15), and parallel orientation of the lateral ventricles; normally the frontal horns lie closer together than the occipital horns
of the lateral ventricles.
