Lumps and Bumps of Ultrasound A patient finding a lump on their body can be extremely terrifying. They spend an immense amount of time considering what would happen to them if it were cancer or some life-altering growth that they would have to live with forever. The chances of the lesion being malignant are slim, but should be thoroughly examined just in case. This is where the diagnostic ultrasound comes in. An ultrasound is an effective tool in the diagnosis of superficial lumps and bumps, and there are many that can be seen via ultrasound. An ultrasound can be used to obtain diagnostic-quality images of anything including malignant masses, cysts, lipomas (benign fatty tumors), abscesses, thromboses and much more. It is always the best practice to correctly diagnose the growth in order to plan the proper steps to prevent future problems. According to a study done by Jason Wagner M.D., Kenneth Lee M.D., Humberto Rosas M.D. and Mark Kliewer M.D., the chance of a patient’s lump being a soft-tissue tumor is 3 per 1,000, with a 99% chance of that tumor being benign. The most common soft-tissue tumor is a benign fatty tumor called a lipoma. Typically, a lipoma is a soft, movable and painless bump that is usually no more than 5cm and is common in people 40-50 years old. On ultrasound, any mass will have a distinct echo pattern to it. When a lump is described as hypoechoic, it means the lesion looks darker than the surrounding tissue on the scan image. A mass described as hyperechoic will appear brighter than surrounding tissue. If the nodule is malignant, it will most likely have irregular boundaries and heterogeneous echo patterns, along with other features, such as the presence of micro calcifications. An ultrasound can be used to detect the “lump or bump,” but a needle biopsy will be required to provide a definitive diagnosis. Another common lump that an ultrasound can be used to identify is a cyst, which is a small sac filled with fluid. Any lesion that is fluid-filled will appear completely black on an ultrasound image. Typically, these types of lesions are hypoechoic or anechoic and have regular consistent borders. Not all cysts are benign, so any lump will need to be examined by a doctor to determine the severity of the case. If the cyst is suspected of being cancerous, a cystectomy will have to be performed. The above examples of lumps and bumps of ultrasound are only a portion of what a sonographer might find. Ultrasounds have proven to be an effective tool for diagnosing many different patient ailments. If a lump or bump is concerning to a patient, it is best to act quickly. Obtaining an accurate diagnosis can bring peace of mind and is one step closer to getting proper treatment.
