Abstract

Pancreatic lesions are a difficult diagnostic and therapeutic challenge owing to
the deep- seated location of pancreas. The present study was conducted to compare
ultrasonography and computed tomography in the assessment of retroperitoneal masses.
Materials & Methods:84 patients with signs and symptoms of retroperitoneal masses of
both genders were enrolled. All underwent USG and MDCT. Data such as name, age, gender
etc. was recorded. All underwent USG and MDCT. Ultrasound was performed with Logiq
P9ultrasoundmachine. MDCT was performed with Siemens Somatom go 32 sliceCT
machine.
Characteristics like size, appearance, echotexture, vascularity and other findings were
studied.
Results: Out of 84 patients, males were 34 and females were 50. Clinical features were lump
in abdomen in 5, pain in abdomen in 32, fullness of abdomen in10, weight loss in 14, loss of
appetite in 22 and trauma in 1 case. Renal abscess was detected correctly by USG in 18 and
MDCT in 20 cases, renal hematoma in 4 and 8, RCC in 7 and 7, complex renal cyst in 13 and
13, pancreatic carcinoma in 7 and 10, adrenal adenoma in 8 and 10, aortic aneurysm in 7 and
9 and pheochromocytoma in 7 and 7 by USG and MDCT respectively. The difference was
non- significant (P> 0.05).
Conclusion: USG can be recommended as a primary screening tool for evaluating
retroperitoneal lesions and CT can be used as a confirmatory tool for the further evaluation of
the complete extent of lesion.
