What causes Xanthochromia in CSF?

The presence of bilirubin in CSF is the main cause of xanthochromia associated with high spinal fluid protein content, usually found above levels of 150 mg/dl.

How long does Xanthochromia CSF last?

Xanthochromia can persist for as long as several weeks after a subarachnoid hemorrhage (SAH). Thus, it has greater diagnostic sensitivity than computed tomography (CT) of the head without contrast, especially if the SAH occurred more than 3-4 days before presentation.

What is SAH in CSF?

Subarachnoid haemorrhage (SAH) is bleeding into the fluid which fills the space around the brain and spinal cord. This fluid is referred to as Cerebrospinal Fluid (CSF). The arachnoid space is one layer of the lining (“meninges”) of the brain and spinal cord. Blood is irritating to the meninges, and can cause pain.

Are macrophages found in CSF?

Macrophages are infrequently found in CSF; they can be classified by the type of material they have phagocytosed. Erythrophages contain red blood cells and fragments of red blood cells. These macrophages can be found shortly after subarachnoid hemorrhage.

Where are the siderophages found in left heart failure?

Heart failure cells are siderophages generated in the alveoli of patients with left heart failure or chronic pulmonary edema, when the high pulmonary blood pressure causes red cells to pass through the vascular wall.

What’s the difference between CBFH and siderophage cells?

In contrast, the cells of cBFH are more eosinophilic, plumper, siderophages; foamy macrophages and collagen trapping are frequently present; and involvement of the subcutaneous fat is much more limited, if present at all.

What does it mean when you have a siderophage?

Siderophages (one indicated by white arrow) and pulmonary congestion, indicating left congestive heart failure. Siderophages (brown spots) in an endometriotic focus. A siderophage is a hemosiderin -containing macrophage.

Which is the most effective ligand for a siderophore?

Siderophores are highly varied in structure ( Figure 1 ), yet generally form hexadentate, high-spin, octahedral complexes with Fe 3+ [1]. In general, siderophores contain bidentate ligand groups; the most effective siderophores contain three of these groups, allowing them to be hexadentate chelators of iron.
