RESUMEN
OBJECTIVE: Differentiating neoplastic from nonneoplastic bone marrow changes on imaging can be challenging. MRI provides the most helpful information when using T1-weighted and opposed-phase (chemical shift) sequences. We discuss the MRI assessment of bone marrow in the context of a complex clinical case. CONCLUSION: The case shows a false-positive result of opposed-phase imaging of bone marrow, which was a postinflammatory cause resulting in marrow fibrosis that mimicked neoplastic marrow infiltration and necessitated biopsy for definitive diagnosis.

CT enterography (CTE) is a technique using neutral oral contrast, intravenous contrast and thin cut, multiplanar CT acquisitions to optimize small bowel imaging. One of the primary indications for CTE is the detection and evaluation of Crohn's disease. This article summarizes the advantages/disadvantages, scanning technique, imaging findings, performance and pitfalls of CTE for the evaluation of Crohn's disease.

We report a case of lumbar facet joint synovial cyst at L5-S1 with clinically significant radicular pain diagnosed by means of MR imaging. This cyst spontaneously resolved, as determined on follow-up MR images obtained 18 months later. The patient's clinical symptoms substantially improved after conservative medical treatment.
