“…The disease begins insidiously and then follows a chronic course. It is characterized by anemia and bone marrow fibrosis, often with accompanying osteosclerosis and extramedullary hematopoiesis [1,2]. Extramedullary hematopoiesis is a compensatory mechanism and is uncommon in adults [2][3][4].…”

“…In a study of 70 cases of myelofibrosis, extramedullary hematopoiesis was almost always seen in the spleen microscopically [7]. Splenomegaly is usually the leading clinical finding, but some degree of myeloid metaplasia is always present in the liver if the spleen is involved [1]. Other less frequent sites of involvement include lymph nodes, adrenal gland, cranial vault, retroperitoneum, breast, spinal canal, renal pelvis, thymus, heart, lung, pleura, skin, dura mater, and epididymis [1,5,7,8].…”

“…As with the sonographic findings, CT appearance of the lesion was not specific. In the literature, CT appearances have been described only in two cases: one had a mixed attenuation pattern with patchy contrast enhancement and the other, in which contrast medium was not used because of renal insufficiency, had a hypodense appearance [1,6].…”

Focal intrahepatic extramedullary hematopoiesis is an extremely unusual condition that can mimic any other solid mass of the liver. Only seven cases have been reported in the literature. Color Doppler ultrasonographic findings of this rare entity have not been described. We report a case of focal mass in a myeloid metaplastic patient diagnosed as focal extramedullary hematopoiesis. Color Doppler findings of this rare condition are described and compared with computed tomography features.

Nodular hematopoiesis of the liver diagnosed by fine-needle aspiration cytology

et al. 1997

View full text Add to dashboard Cite

A case of tumor‐like extramedullary hematopoiesis (EMH) of the liver diagnosed by fine‐needle aspiration cytology guided by computer tomography (CT) is reported. The initial clinical diagnosis was metastatic carcinoma from an adrenal gland primary. Five other cases of tumor‐like EMH diagnosed by FNA have been presented in the literature. In two of the cases, the primary clinical diagnosis was metastatic tumor. The most common location for tumor‐like EMH is paravertebral and intrathoracic. Three such cases of paravertebral tumor‐like EMH have been diagnosed by FNA. Nodular EMH can be found rarely in other organs as in the liver. Diagn.
