We report a case of an AL, which is mimicking a renal cyst, with an emphasis on the symptoms, differential diagnosis, and treatment. Despite the development in imaging techniques, the origin of the cyst could still not be distinguished in some cases. Adrenal cysts are located on the suprarenal area and they can simulate renal, splenic, and pancreatic cysts. Lymphangiomatous adrenal cysts are also known as adrenal lymphangioma (AL). Endothelial cysts are divided into two subgroups: lymphangiomatous and angiomatous cysts. Adrenal cysts are histologically classified into four main groups: endothelial cysts (45%), pseudocysts (39%), epithelial cysts (9%), and parasitic cysts (%7). Its incidence in autopsy series varies between 0,064 and 0,18%. IntroductionĪdrenal cystic lesions are rare and mostly identified incidentally during radiological investigations or at surgery for unrelated reasons. This is the unique case of an adrenal lymphangioma considered as a renal cyst because of its radiological appearance. Adrenal lymphangioma is a very rare lesion. Histologic and immunohistochemical examination demonstrates that the definite diagnosis is cystic lymphangioma of the left adrenal gland. According to clinical and radiological findings, surgical excision was carried out with a subcostal flank incision. Magnetic resonance imaging showed a large, homogenous cystic mass measuring cm with well-defined contours, being hypointense on T1-weighted images and hyperintense on T2-weighted images on the upper pole of the left kidney without a distinct plan between adrenal gland. Abdominal ultrasonography demonstrated a large cystic mass on the upper pole of the left kidney. We present a case of a 44-year-old female who was evaluated for left recurrent flank and abdominal pain.
