Intracerebral injection of oil cyst content of human craniopharyngioma (oil machinery fluid) as a toxic model in the rat brain ( vol 116, pg 448 , 2014)

Summary: This case report describes a 51-year-old man who presented with painful and disfiguring submuscular nodules in the deltoids and gluteal regions. Pre-operative investigations revealed multiple heterogeneous non-vascular fluid collections. It was later discovered that the patient had injected testosterone suspended in oil in those areas 9 years prior. Pathology reports confirmed the presence of granulomas containing yellow viscous fluid and areas of calcification, consistent with the diagnosis of oleomas. This case highlights the importance of considering oil injection as a potential cause of subcutaneous nodules and discusses the complications associated with its use by bodybuilders.
