Case 234: Solitary Fibrous Tumor
45 year old woman with increasing epigastric pain.
US: fibrotic, hypoechoic with acoustic shadowing
US shows the hypoechoic mass in steatosis with strong acoustic shadowing, suggesting dense intralesional material, which prevents visualization of color Doppler flow. Biopsy and resection revealed solitary (mesenchymal) stroma tumor of the liver, a rare entity with dense fibrous stroma causing the acoustic shadowing.
