What is Myelomatous infiltration?
Myelomatous infiltration is characterised by restriction in diffusion when compared with normal marrow, thought to be due to the absence of fat cells, higher cellularity and the destruction of trabecular bone.
What is myeloma of the lungs?
Malignant myeloma (MM) is a clonal proliferation of plasma cells with multiple osteolytic lesions. Extramedullary dissemination of multiple myeloma in lung is relatively uncommon. Hereby, we present a case of multiple myeloma with lung plasmacytoma of lung in a 45-years-old, non-smoker, female.
How does multiple myeloma affect your lungs?
The intraparenchymal causes of respiratory failure from multiple myeloma include alveolar septal amyloidosis, plasma cell infiltration of lung parenchyma, accumulation of alveolar paraproteins, and metastatic calcification of the alveolar walls and blood vessels.
Does myeloma spread to lungs?
CONCLUSIONS: Extramedullary spread of multiple myeloma to the lung is uncommon and very rarely manifests in the form of pulmonary nodules. The presence of extramedullary disease at the time of diagnosis, occurring in over half of extramedullary cases of myeloma, has been associated with poor survival.
What are Myelomatous deposits?
Myelomatous deposits are generally sharply demarcated on a background of an otherwise normal appearing bone marrow. Homogeneous enhancement occurs on T1-weighted images following intravenous contrast injection.
What is a Myelomatous lesion?
Because myeloma is a disease of the medullary compartment of the bone, more subtle lesions can be detected by the appearance of endosteal scalloping that is seen as slight undulation to the inner cortical margin of bone. This finding is indicative of myelomatous involvement in the appropriate clinical setting.
Does myeloma affect breathing?
Myeloma protein can damage the kidneys, resulting in shortness of breath, weakness, itching, and swelling in the legs.
Can myeloma cause breathing problems?
It may be due to the myeloma itself, or to a complication such as anaemia – a condition in which the amount of haemoglobin in the blood or the number of red blood cells is below the normal level, causing shortness of breath, weakness and tiredness.
Can myeloma make you breathless?
Multiple myeloma can affect the production of blood cells in the bone marrow, which can lead to a lack of red blood cells (anaemia). This can also occur as a side effect of myeloma treatment. If you have anaemia, you may feel very tired, weak and breathless.
What does Myelomatous mean in medical terms?
(MY-eh-loh-muh-TOH-sis) A type of cancer that begins in plasma cells (white blood cells that produce antibodies).
Can a lytic lesion be benign?
They are benign, asymptomatic tumors with a well-defined sclerotic margin. They are usually juxtacortical in location and typically occur in the metaphysis of long bones, and are most common in the under 30 age group.
Is multiple myeloma a pulmonary manifestation of interstitial lung disease?
Interstitial lung disease as pulmonary manifestation of multiple myeloma is even rarer; only isolated cases with histological proofs have been reported in the literature. Keywords: multiple myeloma, myelomatous pulmonary infiltrate, lung fibrosis Introduction
What is the prevalence of lung involvement in multiple myeloma?
One study described 13 cases with lung involvement of multiple myeloma, of which six had pneumonia, two had mass lesions, two had multiple nodular lesions, and three had interstitial infiltrates.[3] Approximately 10% of patients with multiple myeloma demonstrate pulmonary findings during the course of their disease.
What causes localized infiltrates of the lungs?
Localized infiltrates are most commonly caused by bacterial (early) and fungal infections (late). Diffuse early infiltrates might be caused by leukemic infiltration of the lungs, pulmonary hemorrhage and/or edema, diffuse alveolar damage, viral pneumonia, and rarely transfusion-related acute lung injury (TRALI) or the differentiation syndrome.
Is pulmonary parenchyma an extramedullary site of multiple myeloma?
Abstract. Conclusions: Pulmonary parenchyma is an uncommon site of extramedullary involvement in multiple myeloma. Interstitial lung disease as pulmonary manifestation of multiple myeloma is even rarer; only isolated cases with histological proofs have been reported in the literature.
