haemosiderin

One of the two forms in which iron is stored in the body. The bulk of the iron is stored as haemosiderin. See also FERRITIN.

A common complication of sclerotherapy is hyperpigmentation of the surrounding skin due to the deposition of haemosiderin.
Thick fibrous bands, haemosiderin pigment and signs of elastotic degeneration were seen.
The term superficial siderosis is used to describe the haemosiderin deposition on the surface of the brain, spinal cord, brainstem and cranial nerve leptomeninges following recurrent subarachnoid haemorrhage.
The gradient echo sequence (GRE) best demonstrates the haemosiderin deposition on the surface of the brain1 and should prompt one to search for the cause of haemorrhage in order to prevent the irreversible neurotoxic effects on the underlying cortex.
The MRI GRE is the most sensitive, (1) and demonstrates thick dark signal lining the nervous system surfaces as a susceptibility artifact due to haemosiderin.
