DEMICHELI, Elisa; ERAZU, Fernanda Rodríguez  and  VAZQUEZ, Cristina. Peduncular Hallucinosis: a Case Report and Topic Review. Anfamed [online]. 2018, vol.5, n.2, pp.123-129. ISSN 2301-1254.

Peduncular hallucinosis is a clinical condition characterized by vivid, colorful, complex visual hallucinations that often recur in time and are described in association with midbrain and thalamic lesions. It is a rare phenomenon and its precise pathophysiology is unknown.

We describe the case of a 38-year-old woman who developed peduncular hallucinosis in relation to extrinsic compression of the midbrain secondary to a vestibular schwannoma.

Clinical features and underlying pathophysiological mechanisms are discussed.

Keywords : Visual Hallucinations; Peduncular Hallucinosis; Schwannoma.
