ABSTRACT

Diagnosis: Liponecrosis Macrocystica Calcificans (Oil cyst)

History: 31 year old female presents for diagnostic mammogram for palpable right breast lump. Patient states mass enlarging over past 11-12 months during pregnancy however stable to slightly decreased in size since cessation of lactation 2 months prior.

Findings: Mammographic images demonstrate a well defined, spherical, lucent mass with a thin calcified rim within the breast parenchyma. Ultrasound images demonstrate a well defined hypoechoic ovoid mass with a thin capsule, edge shadows, and no posterior acoustic enhancement. MRI demonstrates a well defined, nonenhancing mass with a thin capsule with fat signal content characteristics.

Ddx: Oil cyst (Fat Necrosis) Lipoma Harmartoma (fibroadenolipoma)

Dxhow: The combination of mammographic, ultrasound, and MRI characteristics exclude all other diagnosis. The mammographic appearance of a well defined, lucent mass, with thin "egg shell" rim calcifications combined with the MRI confirmation of lipid contents confirmed the diagnosis without need for biopsy.

Exam: Physical exam of right breast demonstrates a firm mobile nontender lump in the upper outer quadrant of the right breast

No MeSH data available.


Contrast enhanced T1W MR with fat suppression image demonstrates decreased signal intensity of the mass confirming fat content. The mass is also nonenhancing.
