| Popis: | The findings at abdominal ultrasonography (US) in 40 patients with myelofibrosis were reviewed, 20 patients being examined at initial diagnosis and 31 at later stages. Splenomegaly was found in 80% at initial diagnosis and in 97% at later stages. The spleen of 2 patients appeared homogeneously hypoechoic and inhomogeneous in one. Focal splenic lesions were seen in 5, and calcifications in 6. Mixed splenic lesions proved to be metastases in one and hyperechoic lesions in another patient were due to extramedullary hematopoiesis. Hepatomegaly was found in 25% at primary diagnosis and in 39% at later stages. Focal hepatic lesions were seen in 7 patients, and proved to be metastases in 3. The focal lesions in 2 of these patients were extramedullary hematopoiesis, which was hypoechoic in one and hyperechoic in the other. Ascites was seen in 4 patients and lymphadenopathy in one. US could not reliably differentiate between extramedullary hematopoiesis and malignancy. Fine-needle biopsy may be performed for definitive diagnosis. |
