RESUMEN
Alagille syndrome is an autosomal dominant and multisystemic disease that generally manifests itself with intrahepatic bile ducts paucity, chronic cholestasis, xanthomas and with other less frequent clinical manifestations such as congenital heart disease, skeletal abnomalies, ophthalmic, vascular, renal and growth failure. Symptoms can be subclinical or very severe. Is caused by various genetic mutations and the majority of patients have a detectable mutation in JAG1 (90%), the remainder have mutations in NOTCH2. The diagnosis is molecular and the incidence is approximately 1 in 30,000 - 50.000. Patient management can be very complex and treatment depends on the district affected and on the symptoms. In more serious cases, with terminal liver disease, liver transplantation is used. We describe a case with main bile duct hypoplasia, intrahepatic bile ducts paucity, cholestasis and gallbladder dimorphism associated with renal malrotation and butterfly vertebrae.
RESUMEN
The Spigelian hernia is a abdominal wall hernia that originates from a discontinuity of the Spigelian fascia located lateral to the rectus abdominis muscle. It can be acquired in adults or congenital in newborns. In very rare cases in male it can be associated with cryptorchidism, in which case it is known as "Spigellian-Cryptorchidism Syndrome". It can be clinically highlighted with abdominal swelling wall along the semilunar line and intestinal obstruction. The diagnosis, as in all pediatric emergencies, must be timely and the method of choice is ultrasound which allows a rapid localization of the hernia breach and herniated structures. The treatment of choice is surgical with herniopexy and repositioning of the testicle into the scrotal sac, or orchipessy in cases of testicular necrosis. We describe ultrasound characteristics of Spigellian-cryptorchidism syndrome presenting with acute intestinal obstruction in a newborn.
RESUMEN
Branchiogenic fistulas are congenital alterations that affect the cervical compartments. Those of the fourth branchial cleft are rarest and can begin late with very serious complications. The suppurative thyroiditis can be a complication of these alterations. We describe a case of 3-year-old girl with high fever, left cervical swelling and increased inflammation indices. The neck ultrasound showed an abscess of the left thyroid lobe and a fluid mass with aerial content in laterocervical region. On MRI, the fluid mass extended from the left piriform sinus to the mediastinum. Fluoroscopy also highlighted a fistolose trait that extended from the left side wall of the esophagus, anteriorly towards the trachea. Treatment of these pathologies must be early and a late diagnosis can put patients' lives at risk.
RESUMEN
Acute colonic diverticulitis (ACD) is the most common complication of diverticular disease and represents an abdominal emergency. It includes a variety of conditions, extending from localized diverticular inflammation to fecal peritonitis, hence the importance of an accurate diagnosis. Contrast-enhanced computed tomography (CE-CT) plays a pivotal role in the diagnosis due to its high sensitivity, specificity, accuracy, and interobserver agreement. In fact, CE-CT allows alternative diagnoses to be excluded, the inflamed diverticulum to be localized, and complications to be identified. Imaging findings have been reviewed, dividing them into bowel and extra-intestinal wall findings. Moreover, CE-CT allows staging of the disease; the most used classifications of ACD severity are Hinchey's modified and WSES classifications. Differential diagnoses include colon carcinoma, epiploic appendagitis, ischemic colitis, appendicitis, infectious enterocolitis, and inflammatory bowel disease. We propose a structured reporting template to standardize the terminology and improve communication between specialists involved in patient care.
