Case Report: Osteomesh Cranioplasty in a 20-Year-Old Trauma Patient

In this study, we present a case of a 20-year-old male who suffered from severe traumatic brain injury with intracerebral hemorrhage, thus requiring decompressive craniectomy. Five months after, the patient underwent cranioplasty with the use of Osteomesh, a scaffold bone filler in reconstructing the post-operative cranial defect.</jats:p

Intraoperative real-time MRI-guided stereotactic biopsy followed by laser thermal ablation for progressive brain metastases after radiosurgery

Stereotactic radiosurgery is one of the treatment options for brain metastases. However, there are patients who will progress after radiosurgery. One of the potential treatments for this subset of patients is laser ablation. Image-guided stereotactic biopsy is important to determine histopathological nature of the lesion. However, this is usually based on preoperative, static images, which may affect the target accuracy during the actual procedure as a result of brain shift. We therefore performed real-time iMRI guided stereotactic aspiration and biopsies on two patients with symptomatic, progressive lesions after radiosurgery followed immediately by laser ablation. The patients tolerated the procedure well with no new neurologic deficits. Intraoperative MRI-guided stereotactic biopsy followed by laser ablation is safe and accurate by providing real time update and feedback during the procedures
