Neuroblastoma Arising in a Retroperitoneal Mature Cystic Teratoma: Case Report

Malignant transformation of mature cystic teratoma is rare and the vast majority are squamous cell carcinoma, but neuroblastomas are extremely rare. We report a case of neuroblastoma arising in a mature cystic teratoma of the retroperitoneum. In a 24-year-old woman with intermittent abdominal pain, sonogram and CT scan show a multiloculated cystic mass with calcification, fat, septum, and small solid component in the left retroperitoneal space. Complete surgical resection of the cystic mass was done and a small neuroblastoma in the septum of the cystic mass was incidentally detected at histopathologic examination.

MR Findings of Acute Rhabdomyolysis: Case Report

Rhabdomyolysis is an acute disorder resulting from skeletal muscle injury in which intracellular contents are released into extracellular space and plasma. The condition may result from drug or alcohol overdose, infection, crush injuries, collagen disease, or intensive exercise. We report two cases of acute rhabdomyolysis resulting from CO poisoning and alcohol overdose, and discuss the MRI and ultrasonographic findings.
