RESUMO
Bone marrow appearances in aplastic anemia are characterized by the abundance of fatty marrow that replaces normal functional marrow. The signal intensity of aplastic bone marrow in sagittal T1-weighted magnetic resonance images of the spine is bright, resembling that of subcutaneous fat and, in most cases, is not difficult to differentiate from normal age-related marrow changes. Three patients with aplastic anemia are described, and the correlation of magnetic resonance imaging of the spine with bone marrow trephine biopsy findings in these patients is portrayed. Magnetic resonance imaging is an accessible, non-invasive technique that allows sampling of a larger volume of bone marrow tissue and is especially useful in the detection of fatty marrow replacement of the normal functional marrow in aplastic anemia.

We are reporting an unusual case of widespread abdominal calcifications, in the peri-colic mesentery, liver and spleen. The diagnostic laparoscopy showed multiple encapsulated calcified hard rounded masses of varying size and shape, with marked adhesions in and around the bowel and mesentery. Histopathology identified them as calcified lymph nodes, but was unable to highlight the pathogenesis of these calcifications. The diagnosis of post tuberculous calcification of lymph nodes is made on the basis of exclusion. The subject was reviewed, to the best of our knowledge, there is no similar case, with such an extent of abdominal calcifications reported in the literature.
