D. Solomon et al., CASE-REPORT - RECTAL STENOSIS DUE TO EXTRAMEDULLARY HEMATOPOIESIS - RADIOLOGICAL FEATURES, Clinical Radiology, 49(10), 1994, pp. 726-728
Although extramedullary haemopoiesis (EMH) is relatively common in mye
lofibrosis, it is seldom symptomatic and rarely involves the intestina
l tract. We report a case in which perirectal infiltrate resulted in c
linically symptomatic constipation. The barium enema showed tubular re
ctal narrowing with mucosal pleating. On computed tomography a poorly
marginated soft tissue mass was shown to be replacing the perirectal f
at.
