International Journal of Case Reports and Images (IJCRI) is an international, peer reviewed, monthly, open access, online journal, publishing high-quality, articles in all areas of basic medical sciences and clinical specialties. Aim of IJCRI is to encourage the publication of new information by providing a platform for reporting of unique, unusual and rare cases which enhance understanding of disease process, its diagnosis, management and clinico-pathologic correlations. ABSTRACT Introduction:

Case Report: We report the case of an 81-year-old woman with a right extrarenal retroperitoneal mass initially misdiagnosed as acute cholecystitis. A definitive diagnosis of angiomyolipoma is typically made after histopathologic examination of the operative specimen, which was not possible in this case. However, modern imaging modalities, particularly CT scan and MRI scan, have made it possible to identify these lesions in vivo. Conclusion: This case highlights that the preoperative diagnosis of extrarenal angiomyolipoma can be challenging. Awareness of their clinicopathological and radiological features is essential.
