A 51-year-old man presented with elastofibroma (EF) of the gluteal region with a concomitant contralateral lesion. The patient presented with a slow growing mass of the proximal third of the right buttock and had swelling, discomfort in sitting, and right-hip pain during walking for 2 months. On MRI, a soft-tissue mass was noted between the gluteus maximus and the gluteus medius muscle. The mass showed similar signal intensity to the surrounding tissue on T1- and T2-weighted images and with linear hyperintense areas in its internal structure. At surgery, a soft, non-encapsulated, irregular, and rubber-like mass was found attached to the gluteus medius muscles. It was pathologically confirmed to be an EF. This unusual manifestation of an EF is discussed.

Article Synopsis
  • The study aimed to analyze the occurrence and imaging characteristics of elastofibroma dorsi (ED) and pelvic elastofibromas in patients over a ten-year period.
  • It involved reviewing medical images for conditions associated with ED, noting thickness and location of the masses in a sample of 88 patients, predominantly female, with an average age of 70.6 years.
  • Results revealed that 18.2% of patients had concurrent pelvic elastofibromas (SGIFE), and those with SGIFE had thicker ED, indicating a significant correlation that could aid in accurate diagnosis.

Background: Elastofibroma is a benign soft tissue tumor characterized by the presence of elastic fibers in a stroma of collagen and mature adipose tissue. It is reported to have a prevalence of 2.73%, as shown by a study through computed tomography (CT) images.
