Learning objectives
To review and illustrate the image findings associated with giant abdominal tumors.
Background
Despite an important increase in radiological explorations,
it is not uncommon to find giant abdominal tumors.
Although the differential diagnosis of giant tumors is wide,
it must be based on a careful review of clinical history,
demographic factors and findings from different image techniques.
CT,
due to its multiplanar range,
allows us to study bigger volumes with better spatial resolution than MRI.
CT also allows for image acquisition during the different phases of contrast distribution and can help to define the origins of the lesion....
Findings and procedure details
We have made a retrospective review of the giant abdominal tumors studied in our hospital in the last five years and we will show the different radiological findings in these patients.
This includes intra and extraperitoneal abdominal lesions (retroperitoneal tumors being the most frequent) and pelvic lesions (mostly ovarian tumors).
GYNECOLOGICAL PATHOLOGY
1. OVARIAN TUMORS
Ovarian neoplasms are the intraperitoneal organ tumors that most often present as large masses.
Benign ovarian tumors are more frequent than malignant ones,
teratoma being the most frequent ovarian neoplasm....
Conclusion
Image studies play a fundamental role in the characterization of giant abdominal tumors and its extension,
local and at distance.
Even though in multiple occasions the anatomopathological analysis is the definitive one,
being familiar with findings coming from imaging techniques helps in narrowing the differential diagnosis.
