An unusual myeloid sarcoma.

Myeloid sarcoma is a tumor mass of immature myeloid or monocytic cells (rarely erythroid or megakaryocytic) occurring in an extramedullary site. A de novo promyelocytic granulocytic sarcoma is a very rare tumor. We report a case of a young man presenting with a paraspinal myeloid sarcoma of promyelocytic origin.

Oblique Lumbar Interbody Fusion With Stereotactic Navigation: Technical Note.

Study Design: Surgical technical note.

Objectives: Describe the preoperative evaluation, approach, and technical considerations for an oblique lumbar interbody fusion using neuronavigation.

Methods: A thorough review of previous technical and anatomic descriptions for pre- and transpsoas interbody techniques was performed and incorporated into the technical considerations warranting discussion for a navigated oblique lateral interbody fusion.

The effect of obesity on perioperative morbidity in oblique lumbar interbody fusion.

Objective: Obese patients have been shown to have longer operative times and more complications from surgery. However, for obese patients undergoing minimally invasive surgery, these differences may not be as significant. In the lateral position, it is thought that obesity is less of an issue because gravity pulls the visceral fat away from the spine; however, this observation is primarily anecdotal and based on expert opinion.

Leptomeningeal metastases presenting exclusively with ocular disturbance in 34 patients: A tertiary care cancer hospital experience.

Leptomeningeal disease (LMD) represents disseminated intracranial metastatic disease that requires early detection and initiation of therapy. Patients with LMD typically present with a variety of neurologic problems, including ocular disturbances. However, little is reported on LMD presenting exclusively with ocular-related disturbances in the absence of any other central nervous system (CNS) dysfunction.
