- To review and illustrate imaging findings of common and uncommon lesions that may mimic malignant mesenchymal tumors. - To review imaging features that should warrant further investigation.
Pseudosarcomas are one of the most important pitfalls in soft-tissue pathology.
They are a vast group of nonneoplastic lesions that can be mistaken for malignant mesenchymal tumors.
computed tomography (CT) and magnetic resonance imaging (MRI) have a key role in the initial evaluation.
An interdisciplinary approach with pathology and correlation with clinical history is also often necessary for a definitive diagnosis.
Imaging findings OR Procedure Details
In this work,
we present a pictorial review of lesions mimicking soft-tissue malignant tumors and review imaging findings that may help guiding the differential diagnosis,
using relevant examples of the daily practice in our institution. Soft-tissue Pseudosarcomas are benignsoft-tissue lesionsthat canbe mistaken formalignancies and should be in the differential diagnosis whenconsidering asarcomatous etiology.

It is important for the radiologist to be familiar with soft-tissue pathologies that may mimic malignant mesenchymaltumors like thepseudosarcomasof this work.
They are a diagnostic challenge but should be in consideration in differential diagnosis,
although in many cases only the pathology study will reveal the correct diagnosis.
