    Abstract Endoscopic retrieval of embedded, proximally migrated, or fractured plastic biliary stents may be technically challenging and sometimes unsuccessful. Percutaneous transhepatic techniques have previously been described to assist in such challenging cases. Here in, we describe a difficult case in which all commonly described endoscopic and percutaneous techniques failed to retrieve a proximally migrated, fractured, and looped plastic biliary stent. We finally successfully retrieved the plastic forceps after off-label utilization of rigid bronchial forceps via a percutaneous transhepatic approach. We describe the technique utilized in detail and this appears to be the first description of this off-label use in this challenging scenario.

    Abstract Percutaneous renal biopsy with ultrasound guidance is a helpful procedure regularly performed to obtain renal tissue diagnosis for rejection in the postrenal transplant setting; however, it is not without risks. We report the case of a 42-year-old male with end stage renal disease who developed a subcapsular hematoma, with subsequent hypertension and renal failure, compatible with acute page kidney as a complication of the renal biopsy. The ultrasound images demonstrated classic imaging appearances which all diagnostic and interventional radiologists should be aware of. The patient was managed successfully with conventional open surgical evacuation of the hematoma with return to baseline laboratories and vital signs after the procedure.

    Abstract Abstract Background Chylothorax is a rare complication of pediatric cardiac operations that occurs more frequently in children with Noonan syndrome, a genetic disorder associated with cardiac defects and lymphatic anomalies. Case presentation We report a case of postoperative chylothorax in a 6-month-old infant with Noonan syndrome where multimodality lymphatic imaging guided management was followed. Drainage patterns of the lymphatic capillaries in the lower and upper extremities were visualized during near-infrared fluorescence lymphatic imaging (NIRFLI). Dynamic magnetic resonance lymphangiography (MRL) further identified the site of leakage in the thoracic duct and subsequently guided surgical intervention. Conclusions Application of multimodality imaging allows for greater individualization of treatment and should be considered in patients with complex cases such as those with syndromes associated with a higher incidence of chylothorax.

    Abstract Spontaneous arterial aneurysms of the hand are uncommon but are well-described in the adult population. In the pediatric population, however, congenital or true aneurysms of the hand are exceptionally rare. A case report and a literature review were performed for published cases of arterial aneurysms of the hand in the pediatric population. A 13-month-old child presented with an aneurysm of the common digital artery and underwent surgical excision without need for reconstruction. Literature review found 13 documented cases. Patient characteristics and management strategies were summarized. There are very few documented cases of hand arterial aneurysms in the pediatric population, with our patient being the third youngest ever reported. No cases were associated with hereditary disease, and aneurysm excision was performed in all cases. Our report highlights the need to include arterial aneurysm in a differential diagnosis when evaluating a pediatric patient with a palpable hand mass.
