Giant retroperitoneal lipomas--radiological case report

A 72-years woman presented with a 4-weeks history of abdominal pain and sickness. Physical examination was normal except for a large, smooth, non-tender solid mass in the right upper quadrant. US demonstrated a 12 x 9 x 4-cm solid, homogeneous, hyperechogenic mass between the posterior abdominal wall and the right kidney and the right lobe of the liver. The primary diagnosis was established as Tumor hepatis. The CT showed a great mass of measurements between - 80 and - 100 Hounsfield units; it filled right half of the abdominal cavity, with focal intratumoral calcifications. The right lobe of the liver, gallbladder, the right kidney, and loops of the small intestine were dislocated and pressured to anterior abdominal wall. The lower pole of the tumor was located in right iliac fosse. It was easily dissected from the adjacent tissues and removed completely. The histopathological diagnosis was lipomas. The next case was a 60-years woman with a 2-months history of pain and gastrointestinal symptoms. US demonstrated a 13 x 12-cm solid, homogeneous, hyperechogenic mass in right epigastria, below the liver. The primary diagnosis was established as abdominal tumor. The CT showed lipomas with numerous septa and calcifications of measurements between -20 and -61 Hounsfield units filling the right half of the abdominal cavity. The right kidney and loops of the small intestine were dislocated to the left side. The root of the tumor seems to be connected with the mesentery of the small intestine. The patient was treated surgically and remains well under regular follow-up.
