Radiology MRI

Axial and coronal T2, axial FLAIR and coronal post contrast T1 show large extaaxial tumor compressing left frontal lobe. Giant meningioma. Tumor has homogeneous structure, is sharply demarcated. It is a slow growing tumor therefore you see no edema in the adjacent brain tissue. Note intense and homogeneous contrast enhancement and spoke wheel vascular pattern. Due to high vascularity meningiomas can occasionally bleed and on such occasion increase in size giving symptoms (not in this case).

Perivascular Spaces PVS (also known as Virchow-Robin spaces) are seen in this 1.5 years old child on transversal T2, IR, coronal FLAIR and sagittal T1 images. Location is typical in the lower parts of the basal ganglia accompanying penetrating arteries. Should not be mistaken with pathological finding. Clinical significance (or lack of it) is being discussed in the literature.

Today I had opportunity to try Toyota iQ for the third time. Like previously as a replacement car while mine was in the service. This time the car was purple. You can read my previous review of Toyota iQ here . I decided to make a note on a very important issue that this car has. The front mounted dashboard island console that really serves no particular purpose is painted in very shiny finish. This combined with horizontal orientation and curvy configuration produces very strong light reflections at almost any bright sun angle . This has really a blinding effect. I have seen notes on discussion groups of users asking how to matt the surface. Toyota should promptly address this problem. Two other issues that came back when driving this cute little car are: quite uncomfortable seats and poor radio controls . Seats are OK for a low budget car but iQ is in the rather high price category for it's class. The other issue is the little joystick mounted on the steering wheel that oper

Unenhanced CT shows symmetric bilateral calcifications in the basal ganglia: nucleus caudatus, globus pallidus, pulvinar in a 30 years old man. Most likely it is the case of Fahr disease however basal ganglia calcifications have a long list of differential diagnosis including metabolic diseases and hypoparathyroidism. Further workup (clinical and with MRI) is of value. See also: Fahr disease from Neuroradiology On the Net Differential diagnosis may also include a rare type of mitochondrial disease.
