Summary of "Early Detection of Secondary Central Nervous System Lymphoma on PET/CT."

We present a case of secondary central nervous system relapse of lymphoma detected initially on PET/CT without corresponding findings on MRI. A 60-year-old lymphoma patient demonstrated an FDG-avid focus in left cerebellar hemisphere on restaging PET/CT. MRI brain showed no corresponding abnormality, and expectant management ensued. Six months later, she represented with metabolic progression of previously seen FDG-avid focus in left cerebellar hemisphere, now also manifesting as an enhancing mass on MRI. Posttreatment scan for presumed lymphoma relapse showed metabolic response. This case demonstrates the advantage of PET/CT over anatomical imaging to detect metabolic changes before structural changes become apparent.

Pre-treatment serum IL-10 predicts the risk of secondary central nervous system involvement in patients with diffuse large B-cell lymphoma.

As diffuse large B-cell lymphoma (DLBCL) is a very heterogeneous group of lymphomas, much effort has gone in trying to identify patients with increased risk for early death or secondary central nervou...

STAT3 activation is associated with IL-10 expression and survival in primary central nervous system lymphoma.

Medical and Biotech [MESH] Definitions

Pathogenic infections of the brain, spinal cord, and meninges. DNA VIRUS INFECTIONS; RNA VIRUS INFECTIONS; BACTERIAL INFECTIONS; MYCOPLASMA INFECTIONS; SPIROCHAETALES INFECTIONS; fungal infections; PROTOZOAN INFECTIONS; HELMINTHIASIS; and PRION DISEASES may involve the central nervous system as a primary or secondary process.

The enteric, parasympathetic, and sympathetic nervous systems taken together. Generally speaking, the autonomic nervous system regulates the internal environment during both peaceful activity and physical or emotional stress. Autonomic activity is controlled and integrated by the central nervous system, especially the hypothalamus and the solitary nucleus, which receive information relayed from VISCERAL AFFERENTS; these and related central and sensory structures are sometimes (but not here) considered to be part of the autonomic nervous system itself.

Inflammation of blood vessels within the central nervous system. Primary vasculitis is usually caused by autoimmune or idiopathic factors, while secondary vasculitis is caused by existing disease process. Clinical manifestations are highly variable but include HEADACHE; SEIZURES; behavioral alterations; INTRACRANIAL HEMORRHAGES; TRANSIENT ISCHEMIC ATTACK; and BRAIN INFARCTION. (From Adams et al., Principles of Neurology, 6th ed, pp856-61)

Infections of the brain, spinal cord, or meninges by single celled organisms of the former subkingdom known as protozoa. The central nervous system may be the primary or secondary site of protozoal infection. Examples of primary infections include cerebral amebiasis, granulomatous amebic encephalitis, primary amebic meningoencephalitis, and TRYPANOSOMIASIS, AFRICAN. Cerebral malaria, cerebral babesiosis, and chagasic meningoencephalitis are examples of secondary infections. These diseases may occur as OPPORTUNISTIC INFECTIONS or arise in immunocompetent hosts. (From Joynt, Clinical Neurology, 1998, Ch27, pp37-47)

Characteristic properties and processes of the NERVOUS SYSTEM as a whole or with reference to the peripheral or the CENTRAL NERVOUS SYSTEM.
