“…5 Sonographic characteristics that may be present in malignant tumors include sizes greater than 5 cm, infiltrated margins, and a disorganized chaotic hyperemic pattern. 6 Most lesions are large at presentation, with sonographic features of varying echogenicity, composition, and degree of hyperemia that are mostly nonspecific. 6 While many sonographic characteristics in soft tissue masses may suggest malignancy, they may also appear in benign masses.…”

Unusual Presentation of Groin Sarcoma Involving the Common Femoral Artery: A Case Report

Sarcomas are characterized by innumerable clinical presentations. Sarcoma tumors involving peripheral vessels are quite rare and not always easy to identify despite the availability of diagnostic tools such as sonography, computed tomography (CT), and magnetic resonance imaging (MRI). This case report discusses the imaging findings of angiography, sonography, and CT, which were the modalities used in this case. Initially, the patient underwent limited duplex ultrasound and CT imaging to evaluate a painful right groin area after right common femoral artery (CFA) angioplasty and laser atherectomy, with left groin access. Sonographic findings demonstrated a large, heterogenous, hypoechoic, and avascular mass surrounding the right CFA. CT imaging of the pelvis described a partially thrombosed pseudoaneurysm surrounding the CFA. Surgical evacuation of what was believed to be a hematoma was performed; a pathology report revealed sarcoma of the groin.

“…One study suggested that when an ultrasound diagnosis is uncertain, a short-term follow-up scan could be performed, although no details are given regarding the time frame. [11] Another paper reported that posttraumatic haematomas or muscle tears should be followed up between 3 and 6 weeks. [12] However, this case has demonstrated that this is not a sufficient time period to assess for interim changes.…”

Soft-Tissue Sarcoma Masquerading as a Haematoma

Sarcomas commonly occur in the buttock and thigh, although the clinical presentation varies with no specific symptoms other than a painless lump. This case study reports on a soft-tissue sarcoma that was initially thought to be a haematoma on ultrasound, despite being rescanned 6 weeks later. The patient presented back to their general practitioner 8 months later with the subsequent ultrasound showing an irregular and hypervascular soft-tissue mass. Further imaging and ultrasound-guided biopsy led to a surgical excision of a myxofibrosarcoma. This case demonstrates the difficulty of differentiating between a haematoma and sarcoma, especially in patients presenting with a history of trauma.

“…52 US is very sensitive in detecting malignant soft tissue tumors. 17 A 2014 study reported US to have a sensitivity of 94.1% and a specificity of 99.7%. 53 Features of malignancy on US are size > 5 cm, infiltrative, ill-defined margins, and markedly increased vascularity.…”

“…As a result, some may mimic malignancy, and MRI or biopsy is needed. 17 Muscle tears can be the source of a hematoma. As they resolve, they can acquire hyperechoic or mixed appearances, with surrounding edema and increased vascularity.…”

The vast majority of soft tissue masses are benign. Benign lesions such as superficial lipomas and ganglia are by far the most common soft tissue masses and can be readily identified and excluded on ultrasound (US). US is an ideal triaging tool for superficial soft tissue masses. Compared with magnetic resonance imaging (MRI), High-resolution US is inexpensive, readily available, well tolerated, and safe. It also allows the radiologist to interact with the patient as a clinician. In this review, we describe and illustrate the lesions with typical (diagnostic) US features. When the appearances of the lesion are not typical as expected for a benign lesion, lesions are deep or large, or malignancy is suspected clinically, MRI and biopsy are needed. The management of suspicious soft tissue tumors has to be carefully planned by a multidisciplinary team involving specialized surgeons and pathologists at a tumor center.
