Diagnosis

Diagnosis of myelonecrosis typically involves a combination of medical history, physical examination, and laboratory tests. These may include:

• Blood tests to check for abnormal levels of blood cells
• Bone marrow biopsy to examine the bone marrow cells under a microscope
• Imaging tests, such as X-ray or MRI, to look for changes in the bone marrow

Treatment
