Recognition of this, and other, rickets patterns allows the radiologist to influence treatment, as described in a very low birth weight infant.

Although not recognized at the time, the histologic sections were typical of the goblet cell excess of cystic fibrosis. Only 18 mo later was cystic fibrosis diagnosed by sweat test following additional symptoms.

The purpose of this article is to present the imaging appearance of common mimickers of appendicitis in children with right lower quadrant pain. CONCLUSION. The majority of children who undergo imaging for suspected appendicitis will end up having an alternative diagnosis. These mimickers can be gastrointestinal, genitourinary, or pulmonary. Familiarity with these alternative diagnoses can aid in the challenging task of imaging right lower quadrant pain in the pediatric population. lthough appendicitis is the most common cause of intraabdominal surgery in infancy and childhood, its clinical presentation and imaging evaluation are frequently quite challenging. The literature shows that the majority of patients who are referred for imaging for suspected appendicitis will, in fact, not have the condition. In pediatric patients suspected of having appendicitis, Sivit et al. [1] found that only 38% who underwent CT and 29% who underwent sonography had the condition. The frequency of alternative diagnoses found with diagnostic imaging shows the importance of an understanding of these possibilities, particularly in the pediatric population. This article will familiarize the reader with the radiographic appearance of the wide spectrum of clinical mimickers of appendicitis in children.

She had five siblings. She remained in Germany when, at the age of 9 months, her parents returned to China. There, her father was shot by authorities and her mother went missing. It was arranged for Inna to stay with friends of the family in Germany. She excelled at school and was made valedictorian of her gymnasium graduating class after making top grades. She was respected by students and teachers alike. She stayed in Berlin and after World War II she lived in the German Democratic Republic (East Germany), where she attended medical school. She maintained her Chinese (People's Republic) passport. She began her career at Berlin's Charité Hospital, where upon the invitation of two professors she began to develop a pediatric radiology service in 1964. She retired from Charité after over 35 years in 1995, having primarily been the chief of Pediatric Radiology. In 1965 she attended the 2nd Congress of the European Society of Paediatric Radiology, that year in Stockholm,

The sign is illustrated in a 2 month-old male infant with considerable bilateral lung disease.

Advances in CT and MR imaging have greatly improved the ability to detect or confirming nonidiopathic causes of scoliosis, including abnormalities within the spinal canal. Three-dimensional thinking has become more important in evaluating and understanding scoliosis.

The zone of Ranvier and the ring of LaCroix, together with the membranous bone bark they produce,... more The zone of Ranvier and the ring of LaCroix, together with the membranous bone bark they produce, are termed the periphysis in order to emphasize their normal effect (the metaphyseal collar) on the metaphysis of the infant and young child. In the first 7 years of life, the normal collar at the wrist is 1-3 mm wide. The step-off between the metaphyseal collar and the curvilinear metaphysis, at the margin of the periphysis, should not be mistaken for abuse fracture. The periphyseal bone bark may be radiologically visible at the edge of the physis at the distal ulna in 9% of infants and should not be mistaken for fracture or rickets.
