Massive pulmonary embolism presenting initially as acute psychosis.

This is a case of a 68-year-old man with Parkinson's disease who was admitted in the psychiatry floor for new-onset aggressive behaviour and hallucinations.

A few seconds later, he went into cardiac arrest; he was resuscitated after multiple rounds of Advanced Cardiovascular Life Support.

A rare highly aggressive tumour: lymphoepithelioma-like thymic carcinoma.

Lymphoepithelioma-likethymic carcinoma is a rare neoplasm that presents with compressive symptoms or as an incidental radiological finding of an anterior mediastinal mass. It is an aggressive carcinoma with a high rate of invasion, metastasis and recurrence. Its diagnosis usually carries a poor prognosis largely due to propensity for late diagnosis.
