Giant orbital oncocytoma.

Background And Importance: Oncocytomas are rare benign tumours often arising from the lacrimal or salivary glands, usually small in size.

Clinical Presentation: We report a giant unilateral orbital oncocytoma in a 19-year-old male from Papua New Guinea, presenting with progressive proptosis-threatening vision. Due to retro-ocular extension of the lesion, surgical excision was performed via a fronto-orbitozygomatic craniotomy and orbitotomy.

Anterior pseudoarthrectomy for symptomatic Bertolotti's syndrome.

Painful L5/S1 pseudoarthrosis has been previously managed with posterior excision and/or lumbar fusion. To our knowledge, the anterior approach for L5/S1 pseudoarthrectomy in the treatment of Bertolotti's syndrome has not been described. We present two patients with severe symptomatic L5/S1 pseudoarthroses that were successfully excised via an anterior retroperitoneal approach with 2 year clinical and radiological follow-up.
