Summary

Depressive symptoms may be the only expression of brain tumours. Thus, it is challenging to suspect a brain tumour when patients with depression have a normal neurological examination. We illustrate this by a case report regarding a meningiomatosis revealed by a treatment-resistant depressive syndrome that improved after surgery. This case highlights the importance of identifying signs of brain tumour in patients with depression. Although there is no consensus about whether brain imaging is indicated for depressive syndromes, it should be performed, particularly in late onset of depressive syndrome (after 50 years of age), treatment-resistant depression or in apathy with a reduced emotional response or without dysphoric manifestations.
