Myelodysplastic syndrome
One of a group of disorders characterized by abnormal development of one or more of the cell lines that are normally found in the bone marrow. Patients can develop a variety of symptoms related to anemia, low or high white blood cell count, infections, and bleeding problems. Myelodysplastic syndrome may progress and become acute leukemia. The well-recognized myelodysplastic syndromes include refractory anemia, refractory anemia with ringed sideroblasts, refractory anemia with excess blasts, refractory anemia with excess blasts in transformation, chronic myelomonocytic leukemia, chronic myelomonocytic leukemia in transformation, and unclassified myelodysplastic syndrome. Also known as preleukemia or smoldering leukemia.

Inflammation of both the spinal cord and the brain. Myeloencephalitis (also called encephalomyelitis) can be caused by a variety of conditions that lead to inflammation of the spinal cord and brain. Among the common causes of myeloencephalitis are viruses which infect the nervous system. One type, acute disseminated myeloencephalitis, occurs most commonly after an acute […]
- Myelogenous
Referring to the nonlymphocytic groups of white blood cells, including the granulocytes, monocytes and platelets. Synonymous with myeloid. Acute myelogenous leukemia is therefore also known as acute myeloid leukemia.
- Myelofibrosis
Spontaneous scarring (fibrosis) of the bone marrow that disrupts the normal production of blood cells, leading to severe anemia and enlargement of the spleen and liver. Myelofibrosis usually begins slowly and worsens over time. It can be associated with a variety of diseases, primarily myeloproliferative (preleukemic) disorders. Also known as agnogenic myeloid metaplasia.
- Myelogenous leukemia, acute
Abbreviated AML. Also called acute myeloid leukemia or acute nonlymphocytic leukemia (ANLL). A quickly progressive malignant cancer that grows from cells within bone marrow those normally turn into white blood cells, the granulocytes or monocytes. The result is too many immature white cells. In AML, these blasts do not mature and so become too numerous. […]
- Myelogram
An X-ray test of the spinal cord and the bones of the spine. A myelogram is used to detect impingement of the spinal cord by bone, disc, or other’ tissues.
