Signo y síndrome de Chilaiditi: condiciones infrecuentes pero con importancia diagnóstica en pediatría: casos clínicos / Chilaiditi’s sign and syndrome: rare conditions but diagnostically important in pediatrics: clinical cases

Aunque poco frecuente, la interposición de intestino entre el diafragma y el hígado, signo o síndrome de Chilaiditi (en relación a la ausencia o presencia de síntomas gastrointestinales), constituye una condición clínica de importancia dadas las posibilidades de diagnóstico diferencial, tales como: neumoperitoneo, hernia diafragmática y absceso subfrénico. OBJETIVO: Presentar dos preescolares con signo y síndrome de Chilaiditi, así como resaltar la importancia de esta condición clínica. CASOS CLÍNICOS: Caso 1: Preescolar varón evaluado por cuadro respiratorio sin síntomas abdominales. La radiografía de tórax mostró infiltrados retrocardíacos izquierdos y presencia de aire en región subdiafragmática derecha. En radiografías previas se encontraba la misma imagen. Se concluyó que se trataba de un signo de Chilaiditi asociado a un cuadro de neumonía, se trató con antibioterapia y se dio de alta. Caso 2: Preescolar de sexo femenino, evaluada por distensión abdominal y constipación. Radiografía de tórax, solicitada previamente por cuadro respiratorio, con imagen de colon derecho situado entre el hemidiafragma y el hígado. Enema baritado de colon confirmó los hallazgos. Exámenes de laboratorio normales. Se concluyó síndrome de Chilaiditi, se indicó tratamiento médico, con buena evolución. CONCLUSIÓN: Se resalta la importancia de esta condición clínica que pese a ser infrecuente constituye un reto diagnóstico en los servicios de urgencia.

Although infrequent, bowel interposition between diaphragm and liver, Chilaiditi’s sign or syndrome (without or with gastrointestinal symptoms), are a major clinical condition given the possibilities of differential diagnosis, such as pneumoperitoneum, diaphragmatic hernia and subphrenic abscess. Objective: To report the cases of two preschool patients with Chilaiditi´s sign and syndrome, as well as to highlight the importance of this clinical condition. Clinical cases: Case 1: A male preschooler evaluated by respiratory disease without abdominal symptoms. Thorax X-ray shows left retrocardiac infiltrates and air in right subdiaphragmatic region. Previous radiographies shows the same image. He was diagnosed with Chilaiditi sign associated with pneumonia, antibiotics were used before discharge. Case 2: A female preschooler, evaluated by abdominal distention and constipation. A previous thorax X-ray shows bowel interposition between diaphragm and liver. Barium enema confirmed the findings. Blood test were normal. A Chilaiditi's syndrome was diagnosed. She received medical treatment with favorable evolution. Conclusion: These cases highlight the importance of this clinical condition that, despite being infrequent, constitutes a diagnostic challenge in the emergency services.

Chilaiditi’s syndrome.

Chilaidit’s syndrome is a rare condition characterised by the interposition of the colon between the liver and the right hemidiaphragm. We present a case of 20-year-old male who reported with breathlessness and epigastric pain, and he was diagnosed radiologically to have Chilaiditi’s syndrome.

Chilaiditi Syndrome – A Diagnosis not to be Missed.

Chilaiditi Syndrome is the transposition of right colon in between liver and right hemidiaphragm. This is a rare syndrome which can be easily mistaken for more serious abnormality like perforated viscus. Here we report on elderly female who presented with Chilaiditi Syndrome.

Síndrome de Chilaiditi / Chilaiditi´s syndrome

A interposição permanente ou temporária do cólon, intestino delgado ou estômago no espaço hepatodiafragmático é conhecido como sinal de Chilaiditi, sendo geralmente assintomático. É evidenciado normalmente em um exame radiológico de rotina. A sua incidência é de 0,025% nos exames radiológicos em todas as idades, aumentando levemente nos pacientes maiores de 60 anos, sendo mais comuns em homens do que em mulheres, com uma relação de 4:1. A associação do sinal de Chilaiditi com sintomas como dor abdominal, náuseas, volvo intestinal, dor retroesternal, sintomas respiratórios, vômitos, distensão abdominal, obstrução ou suboclusão intestinal caracteriza a síndrome de Chilaiditi. No presente estudo, apresentamos um novo caso do sinal de Chilaiditi observado ocasionalmente ao exame radiológico de abdome (AU)

The permanent or temporary interposition of the colon, small intestine or stomach in between the liver and the diaphragm is known as Chilaiditi's sign, usually being asymptomatic. The condition is usually diagnosed in routine X-rays. Its incidence is 0.025% in radiological scans in all age groups, with a slight increase in patients over 60. It is more common in males than females in a ratio of 4:1. The association of Chilaiditi's sign with symptoms of abdominal pain, nausea, intestinal volvus, retrosternal pain, respiratory symptoms, vomiting, abdominal distension, intestinal obstruction or sub-occlusion characterizes the Chilaiditi syndrome. Here we report the case of Chilaiditi's sign as detected in abdominal X-rays (AU)
