Brain biopsy performed with the RONNA G3 system: a case study on using a novel robotic navigation device for stereotactic neurosurgery

Background: Robotic neuronavigation is becoming an important tool for neurosurgeons. Wepresent a case study of a frameless stereotactic biopsy guided by the RONNA G3 roboticneuronavigation system.Methods: A 45 year‐old patient with a history of vertigo, nausea and vomiting was diagnosedwith multiple periventricular lesions. Neurological status was unremarkable. A frameless roboticbiopsy of a brain lesion was performed.Results: Three tissue samples were obtained. There were no intraoperative or postoperativecomplications. Histological analysis showed a B‐cell lymphoma. After merging the preoperativeCT scan with the postoperative MRI and CT scans, the measured error between the plannedand the postoperatively measured entry point was 2.24 mm and the measured error betweenthe planned and postoperatively measured target point was 2.33 mm.Conclusions: The RONNA G3 robotic system was used to navigate a Sedan brain biopsyneedle to take tissue samples and could be a safe and precise tool for brain biopsy.
