Virtual Reality for Preoperative Planning in Complex Surgical Oncology: A Single-Center Experience.

Introduction: Virtual reality models (VRM) are three-dimensional (3D) simulations of two-dimensional (2D) images, creating a more accurate mental representation of patient-specific anatomy.

Methods: Patients were retrospectively identified who underwent complex oncologic resections whose operations differed from preoperative plans between April 2018 and April 2019. Virtual reality modeling was performed based on preoperative 2D images to assess feasibility of use of this technology to create models.

Idiopathic Copper Deficiency Induced Myeloneuropathy.

Idiopathic nutritional deficiencies are often overlooked in patients with no history of malabsorption. However, it may lead to severe neurologic dysfunction that can sometimes be irreversible. We present a case in which early recognition of copper deficiency has led to a better outcome for the patient, who presented with acute myeloneuropathy.
