The failure to ask for a higher resolution images if partially because of priorities. Introduction: We propose that accumulation of focal haemosiderin deposits in older peoples brains in part reflects the inability of the ageing brain to store ferritin iron released from ischemic damage to oligodendrocytes and other cells because of a reduced overall population of remaining healthy brain cells. 2016 Dec;139(Pt 12):3151-3162. doi: 10.1093/brain/aww229. Previous histological analysis of the putamen in the ageing population has suggested that haemosiderin deposition primarily occurs at the capillary level 3, in contrast we report a significantly higher number of haemosiderin deposits in periarterial/periarteriolar regions compared with pericapillary locations.

Neurological picture. Vestibulocochlear nerve (CN VIII) dysfunction resulting in a sensorineural hearing loss is believed to be due to the combination of a long cisternal course (thus with ample exposure to the subarachnoid space) and the susceptibility of microglial cells (which have a role in myelination) to be damaged by iron compounds 4.

Pneumocephalus mimicking cerebral cavernous malformations in MR susceptibility-weighted imaging. The parameters for the susceptibility weighted sequence were: repetition time 29ms; echo time 15ms; flip angle 15; voxel size 0.450.451mm (slice thickness 1mm); number of excitations 2; acceleration factor 1.2. The total number of discrete perivascular and/or neuropil deposits of haemosiderin (as single profiles or clusters of profiles) in the putamen was counted blind to any clinical or pathological data (Figure1a,b). 19. A significantly higher number of haemosiderin deposits were detected in periarterial/periarteriolar regions (mean 7.680.952) compared with parenchymal (pericapillary) locations (2.790.55) (P<0.001) (Figure2b). 2019;1205:25-53. doi: 10.1007/978-3-030-31904-5_3. CT myelogram and SPECT with labeled RBC couldn't help finding the source of occult bleeding. Grouped clusters of several profiles (a; arrow) were counted as a single focus. While two-thirds of the cohort have a density below two deposits per cm2 there is a large tail of cases with more frequent haemosiderin deposition.
