De novo radiologic placement of button gastrostomy: a feasibility study in children with cancer.

Background: Primary placement of percutaneous radiologic button gastrostomy has been successfully performed in adults but research is lacking as to its success in children during cancer treatment.

Objective: To assess the safety and effectiveness of such treatment at a single center.

Materials And Methods: We conducted a 3-year retrospective feasibility study reporting on placement procedure, feeding plan, acute complications and effectiveness of this technique based on the evolution of the weight and weight-to-height during a period of 3 months.

Eight years tumor control with pazopanib for a metastatic resistant epithelioid hemangioendothelioma.

Unlabelled: Epithelioid hemangioendothelioma is a rare connective tissue tumor of vascular origin. It is most commonly found in young to middle aged women, and its clinical behavior is remakably variable from an indolent metastatic tumor to an aggressive rapidly growing neoplasm. Most tumors are diagnosed in an advanced unresectable phase and when clinically aggressive, require systemic cytotoxic treatment of sarcoma.

Late emergence of contrast-enhancing fat necrosis mimicking tumor seeding after renal cryoablation.

Defining radiographic treatment success after percutaneous renal ablation is challenging due to variable ablation zone imaging findings over time. The present report describes two cases of progressively more evident enhancing soft-tissue nodules in the perinephric fat more than 2 years after cryoablation. Despite features concerning for tumor recurrence on computed tomography and magnetic resonance imaging, biopsies revealed fat necrosis in both cases.
