History
Clinical Differential Diagnosis
Splenic disease – neoplasia (hemangioma/hemangiosarcoma/sarcoma), torsion, hypersplenism, congestion, infectious splenitis (bacterial/fungal/protozoal), infarction, malignant histiocytosis.
DX
Malignant histiocytosis
Sampling
U/S guided FNAs were performed. Cytology revealed histiocytic malignant tumor of the spleen and liver.
Sonographic Differential Diagnosis
Multicentric neoplasia of lymphatic origin was suspected, and appeared to involve the medial iliac lymph nodes, spleen and liver.
Image Interpretation
The spleen presented multiple, hypoechoic, target type masses. These lesions were expanding upon the capsule. Similar, hypoechoic nodular changes were noted throughout the liver. Enlarged, round, echopoor medial iliac lymph nodes were seen.
Outcome
No further outcome at this time.
