Role of abdominal computed tomography in evaluating left upper quadrant masses

Area of Science:

• Radiology
• Medical Imaging
• Abdominal Diagnostics

Background:

• Left upper quadrant abdominal masses present diagnostic challenges due to intricate organ proximity.
• Conventional imaging techniques can sometimes misattribute the origin of these masses.

Purpose of the Study:

• To evaluate the efficacy of computed tomography (CT) in accurately determining the origin of left upper quadrant abdominal masses.
• To compare CT's diagnostic performance against conventional radiologic methods for these specific masses.

Main Methods:

• Case series analysis of six patients with left upper quadrant abdominal masses.
• Utilized computed tomography (CT) imaging for detailed anatomical assessment.
• Compared CT findings with initial diagnoses from conventional radiologic techniques and surgical outcomes.

Main Results:

• CT correctly identified nonurologic origins in three cases initially suspected to be renal or adrenal.
• CT reclassified splenic or retroperitoneal masses as renal tumors in two cases.
• CT identified a pancreatic cyst in a case initially presumed to be a renal mass.

Conclusions:

• Computed tomography (CT) significantly enhances the accurate localization and organ of origin determination for left upper quadrant abdominal masses.
• CT proves more sensitive and definitive than other imaging modalities in resolving complex anatomical relationships and mass origins in this region.
