Abstract:
We used magnetic resonance imaging (MRI) to examine the extent of necrosis in the marrow space in three patients with lymphoma who had necrosis in bone marrow biopsies taken from the posterior iliac crest. Two of the patients had multiple focal lesions observed in the spine, pelvis, and femurs. These lesions had MRI characteristics of fluid-filled necrosis within marrow or lymphoma. The third patient exhibited a unique pattern of anatomically extensive marginated lesions otherwise typical of avascular necrosis of bone. These cases provide evidence that MRI can document the extent of necrosis within the marrow space and can differentiate two distinct patterns of necrosis.
Insights
Magnetic resonance imaging (MRI) can document marrow necrosis extent in lymphoma patients. MRI differentiates fluid-filled necrosis from avascular necrosis patterns in bone marrow.
Area of Science:
- Radiology
- Oncology
- Orthopedics
Background:
- Bone marrow necrosis can occur in patients with lymphoma.
- Assessing the extent and pattern of necrosis is crucial for patient management.
Observation:
- Three lymphoma patients with confirmed bone marrow necrosis underwent magnetic resonance imaging (MRI).
- Two patients presented with multiple focal lesions in the spine, pelvis, and femurs.
- The third patient showed extensive marginated lesions resembling avascular necrosis.
Findings:
- MRI identified fluid-filled necrosis within the marrow space in two patients.
- MRI revealed a distinct pattern of marginated lesions in the third patient.
- The study demonstrates MRI's capability to document necrosis extent and differentiate patterns.
Implications:
- MRI is a valuable tool for evaluating bone marrow necrosis in lymphoma.
- Differentiating necrosis patterns may aid in diagnosis and treatment planning.
- Further research can explore MRI's role in predicting outcomes for these patients.
