Good Day.. I have a friend who’s suffering from CVA INFARCT, LEFT MCA DISTRIBUTION CT-SCAN REPORT: Plain axial tomographic sections of the head reveal a small well-defined hypodense lesion in the left parietal deep white matter area. Patchy hypodensities are seen in the bilateral frontoparietal paraventricular white matter areas. The ventricle are enlarged. The cerebral sulci and cisterns as well as the cerebellar folia are widened. No abnormal extra-axial fluid demonstrated. The midline structures are undisplaced. The posterior fossa brainstem and sellar region do not appear unusual. The bilateral vertebral arteries are arteriosclerotic. Mucoperiosteal thickening is noted in the left maxillary sinus and bilateral ethmoid air cells. The petromastoids, included orbits and bony calvarium appear unremarkable. A nasogastric tube is noted with its tip cut off from view. IMPRESSION: Lacunar infarct left parietal deep white matter area. Ischemic changes Vs. white matter disease.

Cardiologist 's  Response
Hi there,
Thanks for writing in. I am a medical specialist with an additional degree in Cardiology. I read your question with diligence. Radiologist who did the scan included the arteries in the field therefore arteriosclerosis changes of arteries are also seen. This was the cause of embolus which occluded supply to the middle cerebral artery. Brain is supplied by a circle of Willis which receives blood from two internal carotid arteries of the left and right side and 2 vertebral arteries of left and right side; this cicle gives rise to two Anterior, two Middle and one posterior cerebral artery. Here left middle cerebral artery is mainly involved causing damage to part of brain supplied by it.
Sinuses lie in the same bone which encloses the brain that is skull so changes in sinus are also seen as sinusitis but that is separate unrelated problem. For specific answer to a particular question you will have ask a premium question. Good Luck.
With Best Wishes
