Objective. To describe two cases of cerebellar hematomas after supratentorial surgeries: a subdural hematoma (case 1) and subdural hygroma (case 2). Materia and Method. An analysis of the clinical records and images of two patients evaluated during 2009 at the Clinicas Hospital and at the Spanish Hospital. Results. Case 1, 70 years old male, with a left hemiparesis and a lucid status after evacuation of subdural hematoma suffered a 2.5 cm bleeding in the cerebellar folias and in the vermis after 72 hs of the surgery. The evolution was unfavorable with a sudden neurological deficit and cardiorespiratory failure. Case 2, 40 years old female, with asymptomatic 1 cm vermian hematoma found in the CT scan control after 72 hs of the surgery. Evolution was without neurological deficit. Conlusion. Supratentorial surgery with considerable outflow of cerebrospinal fluid would be the one most important factor in this complication. The cerebrospinal overdrainage produces cerebellar relaxation with the consequent traction and rupture of the brinding veins toward the tentorium, generating subdural haematomas and cerebellar hemorragic venous infarction. These two cases reported were operated with non aspirative subdural drainages with considerable cerebrospinal outflow for 72 and 48 hs respectively, that is the common etiologic pattern according to most of the authors.
