Value of ultrasound guided needle biopsy of abdominal masses

ABSTRACT

Forty one cases [22 males and 19 females] with abdominal and pelviabdominal masses were subjected to ultrasound guided needle biopsy in Kasr El-Aini Hospital Radiodiagnostic Department. The biopsies were taken from different organs, liver [9 cases], ovaries [6 cases], kidneys [5 cases], small and large intestine [5 cases], pancreas [3 cases], lymph nodes [2 cases], stomach [2 cases], suprarenal gland [2 cases], and spleen [1 case]. Six biopsies were obtained from masses belonging to no sonographically recognized organ of origin. The biopsy results diagnosed 23 lesions as being malignant [true positive], 13 lesions as benign [true negative], and 5 lesions as [false negative], [benign by us, malignant after surgery], no false positive results were reported. The overall accuracy in this study was 87.8%. The results were confirmed either surgically, by endoscopy, autopsy biopsy of other lesions in the patient or by follow-up using other imaging modalities. No significant complications occurred only minor ones in the form of vaso-vagal attacks in two patients. From this work we concluded that ultrasound guided needle biopsy should be the method of choice for biopsy guidance in the abdomen as it is quick, cheep and less hazardous as there is no ionizing radiation or contrast media used
