Unmasking a hidden culprit: late-presenting congenital diaphragmatic hernia beyond infancy: A case report and literature review.

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a rare congenital anomaly with abnormal diaphragm development, typically diagnosed prenatally or soon after birth. Late-presenting CDH presents diagnostic challenges due to nonspecific symptoms that can lead to misdiagnoses. METHODS: This report discusses a 35-month-old female initially presenting with predominant gastrointestinal symptoms and minimal respiratory distress. Initial radiographic findings suggested a left tension pneumothorax, prompting further investigation. RESULTS: Subsequent diagnostic efforts revealed a Bochdalek-type left CDH, with several abdominal organs herniated into the thoracic cavity. The case was managed through laparotomy, where herniated contents were successfully repositioned into the abdominal cavity. This intervention underscores the need for high clinical suspicion and the importance of distinguishing between similar presentations, such as tension pneumothorax and tension gastrothorax, which require different management strategies. CONCLUSION: The case illustrates the importance of considering CDH in differential diagnoses for older pediatric patients with atypical symptoms. Early recognition and appropriate management are key to improving patient outcomes.

Navigating the Diagnostic Journey in Pediatric Gastroenterology: Decoding Recurrent Vomiting and Epigastric Pain in a Child with Glutaric Aciduria Type II.

BACKGROUND: Glutaric aciduria type II (GA II), also known as multiple acyl-CoA dehydrogenase deficiency (MADD), is a rare autosomal recessive metabolic disorder with varied manifestations and onset ages. CASE REPORT: This study presents a distinctive case of a 10-year-old girl who experienced episodic, intermittent vomiting and epigastric pain, particularly aggravated by high-fat and sweet foods. Despite inconclusive physical examinations and routine laboratory tests, and an initial suspicion of cyclic vomiting syndrome, the persistence of recurrent symptoms and metabolic abnormalities (metabolic acidosis and hypoglycemia) during her third hospital admission necessitated further investigation. Advanced diagnostic tests, including urinary organic acid analysis and genetic testing, identified heterozygous pathogenic variants in the ETFDH gene, confirming a diagnosis of GA IIc. The patient showed a positive response to a custom low-protein, low-fat diet supplemented with carnitine and riboflavin. SIGNIFICANCE: This case emphasizes the diagnostic challenges associated with recurrent, nonspecific gastrointestinal symptoms in pediatric patients, particularly in differentiating between common gastrointestinal disorders and rare metabolic disorders like GA II. It highlights the importance of considering a broad differential diagnosis to enhance understanding and guide future medical approaches in similar cases.
