[Retroperitoneal giant angiomyolipoma diagnosed post-partum with lymph node involvement].

HISTORY AND PRESENTING COMPLAINT: A 30-year-old primipara after a normal pregnancy had delivered a 3340 g child. After an uneventful post-partum period she had noticed her abdomen failing to reduce in size.

INVESTIGATIONS, DIAGNOSIS AND TREATMENT: The abdominal sonography discovered a large retroperitoneal tumor. CT and MRI showed a giant tumor which originated from the right kidney. Suspecting the diagnosis of renal liposarcoma the kidney and tumor were excised with removal of enlarged precaval and preaortal lymph nodes. Gross inspection revealed a ca. 3,2 kg myxoid tumor, measuring 27 x 19 x 10 cm. The histological examination of the surgical preparation revealed a retroperitoneal angiomyolipoma.

CONCLUSION

This is the first case of a giant retroperitoneal angiomyolipoma with lymph node involvement diagnosed post partum.
