RESUMO
El vólvulo de la vesícula biliar es una enfermedad preponderante en las personas ancianas y del sexo femenino. En niños es extremadamente raro. El rango de edad ocurre entre los 6 y 13 años, predomina en el sexo masculino, con una relación de 4:1; el paciente más joven reportado en la literatura es de dos años. Es una enfermedad rara en la que el órgano gira a lo largo de su eje comprometiendo su irrigación vascular. Esta enfermedad fue descrita por primera vez en 1898 por Wendel. El primer caso en niños se describió en 1925 por Daux. A la fecha, 14 casos han sido reportados en la literatura inglesa y 38 casos en la literatura japonesa. En México no encontramos registro de casos. Se reporta el primer caso mundial de vólvulo de vesícula en un recién nacido como causa inusual de abdomen agudo. Caso clínico: recién nacido masculino de 24 días de vida con vólvulo de la vesícula biliar que ameritó colecistectomía convencional.
Gallbladder volvulus is a disease most frequently seen in elderly people or women, but its presence in children is extremely rare. Its incidence occurs between 6 to 13 years, it is predominant in males, 4:1. The youngest case described in the literature was a two-year-old. It is considered a rare disease in which the organ rotates along its axis, compromising its vascular irrigation. It was first described in 1898 by Wendel; in children, it was first reported in 1925 by Daux. To date, only 14 cases have been documented in the English literature and 38 in the Japanese. In Mexico we did not find any case recorded. We report the first world-wide case of gallbladder volvulus in a newborn as unusual cause of acute abdomen. Case report: 24-day-old male newborn with acute abdomen due to a gallbladder volvulus that required conventional cholecystectomy.
RESUMO
Renal artery aneurysm is a rare disease in children and usually is due to fibromuscular dysplasia. Clinical symptoms are frequently high blood pressure, abdominal pain, and hematuria. Diagnosis is carried out by means of angiography. We report the case of a 13-year-old male patient who had renovascular hypertension due to calcification and aneurysm of fibromuscular dysplasia-associated renal artery. We carried out total nephrectomy to resolve high blood pressure. We suggested that presence of discreet calcification in region of renal artery in a boy with renovascular high blood pressure should guide us toward diagnosis of fibromuscular dysplasia-related renal artery aneurysm.
