Objective: The differentiation between a 'non-organic' depressive episode and an organic depressive disorder on the basis of clinical grounds might be challenging.
Methods: We report a case with an initially typical severe depressive episode without any focal neurological deficits.
Results: Only medical history from a third party raised doubts about this provisional diagnosis. Brain magnetic resonance imaging revealed a highly malignant diffuse large intracerebral B-cell lymphoma in the right frontal lobe changing the diagnosis into an organic depressive disorder. The patient recovered after neurosurgical resection, chemotherapy and autologous stem cell transplantation.
Conclusion: This report helps to reduce possible errors in the differential diagnosis of depressive disorders by underlining the importance of a comprehensive medical history including anamnesis from a third party and neuroimaging, especially in first or atypical manifestation of depressive disorders.
