Outcome of intrahepatic portosystemic shunt diagnosed prenatally is good in the majority of cases. What is known: • Multiples studies exist on congenital porto systemic shunt but when the diagnosis is done after birth. • The evolution, management, and complication are well known. What is new: • There is very few studies with only patients diagnosed in antenatal and it is a large series of cases. • Outcome of intrahepatic portosystemic shunt diagnosed prenatally is good in the majority of cases.

First described in HIV-infected patients who recently initiated highly active antiretroviral therapy, the immune reconstitution inflammatory syndrome (IRIS) is best characterized as a collection of inflammatory disorders triggered by rapid resolution of immunosuppression. Treatment of IRIS is a clinical challenge due to the variety of clinical presentations and the presence of multiple pathogens capable of causing the syndrome. Hepatosplenic candidiasis, an uncommon form of invasive Candida species infection, was recently suggested to belong to the spectrum of fungus-related IRIS. We report 2 cases of probable hepatosplenic candidiasis according to the guidelines of the European Organization for Research and Treatment of Cancer and the Mycosis Study Group, occurring in pediatric patients with acute leukemia during rapid neutrophil recovery after cytotoxic chemotherapy. In both cases, abdominal computed tomography scan revealed multiple hepatic micronodules, and liver biopsy showed nonspecific granulomatous lesions. Hepatosplenic candidiasis symptoms (fever, nausea and vomiting, abdominal pain) resolved within 2 days after adjunction of corticosteroid therapy to antifungal treatment. Inflammatory markers and related radiologic abnormalities decreased or disappeared within 1 month. Recovery of neutrophil count in a context of hepatosplenic candidiasis may result in a heightened inflammatory response. Corticosteroid therapy in this setting is associated with prompt resolution of the symptoms.

Objective This study was undertaken to describe the spectrum of lung computed‐tomography (CT) findings in children with pulmonary Langerhans cell histiocytosis (PLCH) and to evaluate for this population the CT‐scan nodule and cyst scores proposed by adult pulmonologists at diagnosis and during follow‐up. Methods Among 175 children with PLCH identified in the French national population‐based Langerhans cell histiocytosis cohort, 60 were retrospectively selected by the availability of CT for a central review by three pediatric radiologists. These 60 patients are representative of childhood PLCH for almost all clinical aspects, except a lower percentage of risk organ involvement (38% vs 54%; P = 0.05). Results The 60 children's chest CT scans (n = 218) were reviewed. At diagnosis, 63% of them had nodules, 53% had cysts, and 29% had both. The percentages of patients with nodules or cysts increased from diagnosis to peak disease activity, respectively, from 63% to 73% and from 53% to 66%. The costophrenic angle was involved in 71%. Patients with pneumothorax (25%) had a higher median cyst score. Alveolar consolidation was observed in 34%. Patients with low CT‐scan nodule and cyst scores had no long‐term pulmonary sequelae. Conclusions Well‐known characteristics of adult PLCH (nodules and cysts) were observed in children. The chest CT scores proposed by adult pulmonologists could easily be applied to childhood PLCH. Lesions in children, unlike those in adults, are frequently located near the costophrenic angles. Alveolar consolidation might be considered an atypical feature of childhood PLCH.
