Summary
Bone marrow necrosis (BMN) is a rare condition distinct from avascular necrosis (AVN), with a unique MRI signature. Recognizing BMN on MRI aids in early diagnosis and prompts investigation for potential underlying malignancy.
Area of Science:
- Radiology
- Oncology
- Pathology
Background:
- Bone marrow necrosis (BMN) is a rare clinicopathologic entity.
- Distinguishing BMN from avascular necrosis (AVN) is crucial for accurate diagnosis and patient management.
- Magnetic Resonance Imaging (MRI) plays a vital role in evaluating bone marrow pathology.
Purpose of the Study:
- To illustrate and review the MRI characteristics of histologically confirmed BMN cases.
- To review existing literature on BMN, focusing on its differentiation from AVN.
- To highlight the importance of recognizing BMN's MRI appearance.
Main Methods:
- Review of histologically proven BMN cases.
- Analysis of MRI findings in these cases.
- Literature review on BMN and AVN.
Main Results:
- BMN is a distinct clinicopathologic entity separate from AVN.
- BMN exhibits a characteristic MRI appearance.
- BMN is frequently associated with underlying malignancy.
Conclusions:
- BMN has a distinctive MRI appearance that aids in its diagnosis.
- Increased use of MRI in bone marrow disease evaluation will likely lead to more frequent BMN identification.
- Early diagnosis of BMN through MRI awareness can facilitate the detection of occult malignancies.

01:24Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
01:29Blood and Nerve Supply to the Bones
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

01:30Radiological Investigation II: MRI and Ventilation Perfusion Scan
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

01:16Cellular Injury IV: Necrosis
Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...
01:16Necrosis
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...

01:27Imaging Studies IV: Magnetic Resonance Imaging
Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
