Chloroma of the Cerebellopontine Angle: A Rare Presentation.

This article presents a case study of a 7-year-old female patient with a history of acute myelogenous leukemia, previously treated with chemotherapy. The patient developed acute right peripheral facial paralysis and right upper limb weakness, leading to the discovery of an extra-axial solid lesion at the right cerebellopontine angle. This lesion extended into adjacent structures with notable contrast enhancement and restricted diffusion on magnetic resonance imaging, indicative of chloroma, an extramedullary solid mass composed of myeloid precursor cells.

HCT in the widening spectrum of congenital immunodeficiencies.

Purpose Of Review: Hematopoietic stem cell transplantation (HSCT) and inborn errors of immunity (IEI) have been closely linked since transplantation was first used to cure severe combined immunodeficiency (SCID) in 1968. Since then, novel genes and diseases have been continually added to the ongoing list of IEI, and new data on indications and outcomes have emerged. We review recent data and progress in the field of hematopoietic cell transplantation (HCT) for IEI including new diseases and complications.

PERCUTANEOUS CHOLANGIOSCOPY AND LASER BILIARY LITHOTRIPSY FOR BILIARY INTRAHEPATIC STONES MANAGEMENT: CASE REPORT.

Intrahepatic biliary stone disease is a difficult condition to treat, due to anatomical complexity of biliary tract, association with colestasis, and high recurrence rates, with potential short- and long-term complications, such as cholangitis and secondary biliary cirrhosis. Removal of biliary stones via intraductal access can be achieved endoscopically or percutaneously, with preference for cholangioscopy-guided laser lithotripsy in complex cases. The surgical approach, despite its prolonged results, is a more invasive and risky procedure.
