We present a paraspinal amyloidoma found incidentally in a 77-year-old man during lymphoma workup by F-FDG PET/CT. A solitary FDG-avid paraspinal lesion was seen at T11-T12. MRI showed T2 hypointensity and enhancement. Lymphoma was considered the primary differential due to FDG uptake, but biopsy revealed nodules of extracellular acellular homogeneous material with apple-green birefringence on Congo red stain consistent with amyloidoma. Spinal amyloidoma is rare with few cases reported so far in literature.

Intramuscular myxomas (IMMs) are rare benign tumors of mesenchymal origin that are most often located in large skeletal muscles, particularly of the thigh. They have also been reported within the para...
Muscle injuries are very common in sports medicine, but involvement of the paraspinal muscles is relatively rare. The diagnosis is usually clinical, but diagnostic imaging modalities (ie, ultrasound ...
Sarcopenia in the lumbar paraspinal muscles is receiving renewed attention as a cause of spinal degeneration. However, there are few studies on the precise concept and diagnostic criteria for spinal s...
Syringic acid, which is a typical methoxyphenol emitted from wood combustion, can provide heterogeneous reaction sites for gaseous active components, influencing the concentrations of trace gases and ...
We present 2 cases of malignant peritoneal mesothelioma (MPM) characterized by a localized solid mass without ascites and showing F-FDG uptake. A 79-year-old man with a history of asbestos exposure su...
The SciExVR study will evaluate the potential benefit of autologous bone marrow derived stem cells (BMSC) in the treatment of spinal cord injury with evidence of impaired motor or sensory ...
Sarcopenia on lumbar paraspinal muscles is receiving renewed attention as a cause of spinal degeneration. Both the atrophy and fatty change of paraspinal muscles originated from sarcopenia...
Protein intake in spinal fusion surgery can prevent paraspinal muscle atrophy by maintaining muscle mass, regeneration, and growth. Also, by reducing the amount of pseudarthrosis, pain and...
During anesthesia, neuromuscular blocking agents (NMBA) are routinely used for relaxation of muscles necessary for the conduction of the surgical procedure. Train-of-four (TOF) test is bas...
In order to evaluate the difference in beta cell mass in women with and without a history of gestational diabetes mellitus (GDM), investigators aim to compare quantitative PET imaging of t...
A mass spectrometry technique using two (MS/MS) or more mass analyzers. With two in tandem, the precursor ions are mass-selected by a first mass analyzer, and focused into a collision region where they are then fragmented into product ions which are then characterized by a second mass analyzer. A variety of techniques are used to separate the compounds, ionize them, and introduce them to the first mass analyzer. For example, for in GC-MS/MS, GAS CHROMATOGRAPHY-MASS SPECTROMETRY is involved in separating relatively small compounds by GAS CHROMATOGRAPHY prior to injecting them into an ionization chamber for the mass selection.
An analytical method used in determining the identity of a chemical based on its mass using mass analyzers/mass spectrometers.
Drugs that inhibit the transport of neurotransmitters into axon terminals or into storage vesicles within terminals. For many transmitters, uptake determines the time course of transmitter action so inhibiting uptake prolongs the activity of the transmitter. Blocking uptake may also deplete available transmitter stores. Many clinically important drugs are uptake inhibitors although the indirect reactions of the brain rather than the acute block of uptake itself is often responsible for the therapeutic effects.
Drugs that block the transport of DOPAMINE into axon terminals or into storage vesicles within terminals. Most of the ADRENERGIC UPTAKE INHIBITORS also inhibit dopamine uptake.
Deep muscles in the BACK whose function is to extend and rotate the SPINE and maintain POSTURE. It consists splenius, semispinalis, multifidus, rotatores, interspinales, intertransversarii and sacrospinalis.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
