Soft Tissue Masses Jon A. Jacobson David P. Fessell INTRODUCTION Ultrasound is routinely used to evaluate palpable soft tissue masses.1 Ultrasound differentiates cystic from solid masses, which often require biopsy to exclude malignancy,2 and can identify superficial soft tissue tumor margins and local tumor spread.3 Limitations primarily relate to evaluation of deep soft tissue structures,… Ultrasound Cases. Home; Cases; Select Category Abdomen and retroperitoneum. 1.1 Liver 1.2 Gallbladder and bile ducts 1.3 Pancreas 1.4 Spleen 1.5 Appendix 1.6 Ultrasound, CT or MRI alone result in correct diagnosis in < 33% of patients (Clin Radiol 2020;75:88) Ultrasound + CT + MRI with or without angiography result in correct diagnosis in 52% of patients (J Surg Oncol 2011;103:807) Ultrasound The classical appearance of a fat-rich AML on ultrasound (US) is that of a hyperechoic lesion with a posterior acoustic shadow (Figure 1 ). The hyperechoic nature of a classic AML is the result of the combination of its fat, blood vessel, and muscle contents, while the shadowing is due to the multiple tissue interfaces between those different elements [ 11 ].

The author has previously noted that angiolipoma is considered as one of the painful cutaneous and subcutaneous tumors accompanied with vascularized appearance using high-resolution ultrasound in dermatology [15]. Angiolipoma also tends to be smaller than 20 mm [20]. The natural history of renal angiomyolipoma is not well delineated. Current management options include observation, embolization, and partial or total nephrectomy. Recommendations for treatment are usually based on the patient's symptoms or the size of the lesion.

Under the diagnosis of an intrascrotal solid mass, a right inguinal radical orchiectomy was performed. Histopathological examination concluded to a paratesticular Se hela listan på radiologykey.com Ultrasound examination of kidney reveals increased size of kidney with tumor. Ultrasound of brain, liver and other soft tissue are also performed to rule out tumor in other organs. Tuberous Sclerosis is often associated with Kidney Angiomyolipoma. Dr. Taco Geertsma is the founder of UltrasoundCases.info and a retired radiologist and has worked in the Gelderse Vallei hospital from January 1, 1983. till July 1, 2014.

Finally, we conclude that angiolipoma of the breast may contain microcalcification mimicking breast carcinoma on mammogram. Abdominal ultrasound (US) revealed concentric circles in the right abdomen. Finally, partial enterectomy was performed. Postoperative histopathologic examination showed angiolipoma of the terminal ileum. During the 3-year follow-up, the patient showed no recurrence.

In the case of less fat content and excess vascular component, angiomyolipoma can be seen as a heterogeneous hypoechoic mass lesion.
