Approximately 3 months after presentation, after completion of a 28-day course of metronidazole, the patient was asymptomatic. Most neoplasms completely replace or displace fat in the marrow space; thus, the neoplastic area will lack normal signal dropout on out-of-phase images [1, 17-19]. Some signs and symptoms of lymphoma are: There are three major types of bone marrow cancer. Red bone marrow reconversion refers to the process of mature yellow marrow being replaced by hematopoietic red marrow. Using a 1.5-T magnet, water and fat protons are in phase with one another at a TE of 4.6 milliseconds. These changes could not be explained simply by local bone marrow hyperplasia ( Figure 3 ), thus raising strong suspicion for a hematologic malignancy.
