Congenital cervical teratomas.

Congenital cervical teratomas are rare, representing 3% of teratomas in childhood. Although mostly benign, they are associated with a high mortality rate due to respiratory distress and require immediate surgical excision. The diagnosis is usually suggested on the physical examination. The imaging investigation is essential for the proper diagnosis and preoperative planning. We present the imaging characteristics of cervical teratomas identified in five neonates over a 10-year-period. The masses were surgically resected. Histopathology revealed the presence of congenital teratomas (three immature, two mature). Two neonates died soon after surgery, while the remaining were discharged from the hospital without symptoms.

Long-term findings on brain magnetic resonance imaging in acute encephalopathy with bilateral striatal necrosis associated with measles.

The long-term findings on brain magnetic resonance imaging (MRI) in a 7 10/12-year-old boy with a history of acute encephalopathy with bilateral striatal necrosis following measles at the age of 22 months are described. At the early stage of illness, brain MRI studies revealed bilateral, symmetric basal ganglia lesions, predominant on the globi pallidi, appearing as hyperintense signals on T1- and T2-weighted images. Six years later, follow-up brain MRI studies showed that the bilateral, symmetric lesions on the globi pallidi persisted with low signal on T1- and high signal on T2 weighted images. At present, the patient has some persistent neurologic signs. These findings suggest that both clinical and neuroradiologic findings may persist in children with acute encephalopathy with bilateral striatal necrosis following measles.
