Biopsia de linfadenopatía retroperitoneal guiada por imágenes con abordaje trans-vertebral: reporte de un caso

INTRODUCCIÓN: Transosseous biopsy allows sampling of lesions that are difficult to access with conventional techniques. Its use avoids surgeries. OBJECTIVE: To present a clinical case in which retroperitoneal percutaneous biopsy with trans vertebral approach was used. A brief bibliographic revision of this technique will be made. CASE: 60 year old woman with endometrial adenocarcinoma, with 7 months of clinical symptoms characterized by asthenia and non-specific lumbar pain. An intercaval aortic lymphadenopathy was found. Trans vertebral biopsy of the lesion was decided, its location precluded conventional approaches access. CONCLUSION: This technique must be considered when studying unreacheable lesions by other means and performed by trained professionals.
