The fundamental work on infundibular tumors was that of Weisenburg,1 in 1910, which detailed thirty cases that had been completely studied. In his second case was the first description of a thalamic type of infundibular tumor; the author noted pain of the central type and vasomotor or trophic disturbances on the opposite side, these symptoms being due to direct destruction of the thalamus by the neoplasm. This is an exceptional case, as evidenced by the fact that in three of the thirty cases reported the thalamus was compressed without giving rise to specific clinical symptoms. Weisenburg also cited a case of Barié in which anesthesia of both extremities was present.
Other extrapyramidal symptoms—tremor, involuntary rhythmic movements, states of rigidity, fits, bradylalia, facial rigidity and slowness of gait—have been reported by Berger-Erdheim,2 Bregmann-Steinhaus,3 Russell,4 Claude and Schaeffer,5 Thomas, Jumentié and Chausseblanche,6 Sainton and Peron7
