Multiple visceral hematomas in a child with familial Mediterranean fever: polyarteritis nodosa.

A 14-year-old girl was diagnosed with familial Mediterranean fever (FMF) with homozygous for M694V mutation of the MEFV gene and was started on colchicine therapy 4 years before admission to our hospital. She was uncompliant to therapy and was admitted to a local hospital with complaining of fever, malaise, abdominal pain and artralgia lasting for 2 months. Multiple hypoechogenic mass lesions were detected on liver and kidneys with ultrasonography (US) and diagnosed to be hematomas by laparoscopic examination.
