Radiological
Report :
Clinical
History : Clinically and biochemically has Acromegaly.
MRI Head :
There is a large lobulated mass arising from an expanded sella with
a component extending into the left middle fossa and a smaller
lobule extending back to impinge on the brainstem. In the midline
sagittal section the tumour is 47mm in height, 38mm AP dimension and
impinges on the optic chiasm.
The component
extending to the left indents the temporal lobe and indents the mass
of the brain extending close to the insular cortex. This component
has a maximum 36mm diameter on the axial images and indents the
inferior part of the lentiform nucleus extending up close to the
left cerebral peduncle.
A further
lobule extending posteriorly in the midline lie in contact with the
upper pons. There is local mass effect around the base of the brain
but no sign of any hydrocephalus. In the parasellar region tumour
seems to wrap around lateral to the internal carotid artery but
there is no sign of any significant carotid stenosis.
Expansion
inferiorly produces a substantial mass extending into the
nasopharynx. |
