Describe and illustrate the radiological characteristics of soft tissue sarcomas located in the abdomen,
pelvis and abdominal wall.
Sarcomas are a large and diverse group of malignant tumours of mesenchymal origin.
It can be divided in soft tissue sarcomas and bone sarcomas. Soft tissue sarcomas affect all ages and can arise anywhere in the body.
Represent less than 1% of malignant tumours. Those sarcomas that arise in the abdomen and pelvis can appear in retroperitoneum,
peritoneal cavity and abdominal wall. When a mass is discovered in the retroperitoneum,
soft-tissue sarcoma should be considered at the top of the...
Findings and procedure details
We review the clinical and radiological findings of the sarcomas located in the abdomen,
pelvis and abdominal wall,
showing the most representative cases of our hospital in the last 5 years. 1. Radiologic Evaluation of Soft-Tissue Sarcomas Ultrasonography may be used as an initial technique during the evaluation of patients with abdominal complaints or palpable abdominal wall masses. Computed Tomography (CT) is the most widely used cross-sectional imaging modality for the abdomen and pelvis...
Knowing the spectrum of common and uncommon soft-tissue sarcomas arising in the abdomen and pelvis is important to establish an accurate working differential diagnosis. A careful evaluation of preoperative images is necessary to plan a surgical resection.
Determine the relationship of the tumour to adjacent solid viscera,
and the abdominal wall is very important. In general,
biopsy is necessary for all masses that are not clearly liposarcoma,
because the imaging features...
