62-year-old male with left hip pain There is a lobulated, septated mass of fluid signal intensity situated lateral to the supra-acetabular left ilium as well as within the gluteus minimus muscles, which measures approximately 6 x 4 cm in transverse dimensions and 5.5 cm in craniocaudad dimension. A tail of fluid also extends along the indirect tendon of the rectus femoris. Mild peripheral and septal enhancement of the fluid collection is noted. The cyst connects with a small acetabular cyst as well. This most likely represents a ganglion or para-labral cyst. Moderate osteoarthritis affects the left hip joint. Although the exam was not protocoled for evaluation of the labrum, irregularity of the anterosuperior labrum likely represents degenerative tearing. Trace fluid is present within the joint itself. Moderate osteoarthritis affects the right hip with a small amount of fluid within the joint. Degenerative arthritis affects the SI joints, particularly on the left. Moderate osteoarthritis also affects the pubic symphysis. There is mild edema within the rectus femoris muscles bilaterally, which is nonspecific and may represent bilateral strains. There is also a collection of fat posterior to the right rectus femoris which is incompletely visualized and may represent a lipoma. Mild edema adjacent to the greater trochanters bilaterally is not necessarily of any clinical significance.
1. Cystic collection adjacent to the left hip as described above, which may represent a para-labral cyst or ganglion and does not have the appearance of an abscess or neoplasm.2. Osteoarthritis and other findings as described above.
