title: Omental cakes: unusual aetiologies and CT appearances.
abstract: BACKGROUND: Omental cakes typically are associated with ovarian carcinoma, as this is the most common malignant aetiology. Nonetheless, numerous other neoplasms, as well as infectious and benign processes, can produce omental cakes.  METHODS: A broader knowledge of the various causes of omental cakes is valuable diagnostically and to direct appropriate clinical management.  RESULTS: We present a spectrum of both common and unusual aetiologies that demonstrate the variable computed tomographic appearances of omental cakes.  CONCLUSION: The anatomy and embryology are discussed, as well as the importance of biopsy when the aetiology of omental cakes is uncertain.
