A 9-month-old infant who was diagnosed to have right-sided diaphragmatic hernia with no other associated anomalies, is being reported here. He had presented with cough for one month and respiratory difficulty for one-week duration and history of bilious vomiting two days prior to admission. His chest X-ray showed multiple lucent shadows in the right lower zone in A-P and lateral views, with not very well defined diaphragm on the same side. A diagnosis of staphylococcal pneumonia was considered but with clinical and radiological picture, a right-sided diaphragmatic hernia was strongly suspected which was confirmed by doing fluoroscopy and CT-scan of the chest. He underwent a successful correction of the defect. So radiological finding of pleural effusion with displacement of mediastinum to the left and the presence of bowel gas high in the right upper quadrant should alert the possibility of a right-sided Bochdalek hernia.

This is a review of 122 articles published until December 2003 that describe 349 children with late-presenting postero-lateral congenital diaphragmatic hernia (CDH). Data regarding pre-operative diagnostic work-up were adequately reported in 177 patients with left CDH and in 41 with a right-sided defect. Chest radiography was the only diagnostic study in 92 (51.9%) children from the former group and in 17 (43.9%) from the latter group. In other patients, diagnostic work-up encompassed various combinations of two or more imaging modalities. Apart from chest radiography, contrast study of the upper gastrointestinal tract was the most frequently performed imaging modality. In 88 (25.2%) children, initial radiographic features of CDH were misinterpreted. Pneumothorax and pleural effusion were the most common initial findings. Analysis of the hernial content in this group of patients has shown that herniation of the stomach, spleen or omentum should be regarded as risk factors for misdiagnosis of left CDH, whereas for right CDH, the risk factor is the presence of liver in the chest. Late-presenting CDH may pose a significant diagnostic problem because of the great variability of radiographic appearance. Chest radiography following passage of a nasogastric tube and contrast studies of the gastrointestinal tract seem to be the most useful investigations for the diagnosis of left CDH. For patients with right CDH, owing to the high probability of liver herniation, a chest radiograph with liver scintigraphy or CT seems to be the best diagnostic option.
Articles dealing with late-presenting congenital diaphragmatic hernia (CDH) in children published until 2003 were collectively reviewed. The main purpose of the presented study was to gain insight into the clinical spectrum of this variant of CDH and to discuss its clinical and surgical aspects. In 125 articles, 362 patients were reported. Left posterolateral hernia was the dominant anatomical type, found in 79.4% of the children. Male-to-female distribution was nearly 2:1 in both right- and left-sided CDH. Associated anomalies were noted in 8.6% of children. Sixty-five percent of children with right CDH presented within the 1st year of life, whereas only 41.7% of patients with left CDH belonged to this age group. The children with right CDH presented with chronic symptoms in 57.4% of cases, while among those with left CDH, acute presentation prevailed, constituting 60.5% of this group. No strict correlation between age and clinical symptoms was noted, although the youngest patients tended to present with respiratory symptoms. Late-presenting diaphragmatic hernia is associated with a wide range of clinical symptoms occurring in various constellations. Dyspnea and vomiting were the most frequent symptoms found in patients with either chronic or acute manifestation. Preoperative mortality was 3.9% (14 children). In 45 children (12.4%), complications resulting from diaphragmatic hernia were noted, and in a further 11 children iatrogenic preoperative complications were noted. Among 152 children with reported CDH, true hernia with sac was found in 32.7%. Eight children (2.2%) died in the early postoperative period, while a further 13 patients (3.6%) had postoperative complications requiring surgical management. Recurrence of hernia was noted in seven children (1.9%). This collective review of basic epidemiological and clinical data from a large group of patients seems to support a hypothesis for a congenital nature of the diaphragmatic defect and an acquired nature of "herniation" of the viscera. The wide clinical spectrum of late-presenting CDH seems to be conditioned by two factors: timing of herniation and type of intraabdominal viscera displaced into the chest.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
