During the early 1900s, Pascual Pinon, a Mexican man, possessed two heads and was a featured performer in the Sells-Floto Circus. Pinon’s second head emerged in an upright orientation, unlike the typical craniopagus parasiticus condition where one head is positioned upside down atop the other. Despite this unusual circumstance, Pinon’s second head was located upright, resembling his own.
A severe headache prompted Pinon to part with his second head.
The doctor said that the removal of his second head was necessary to safeguard his life. Remarkably, Pinon remained conscious throughout the procedure, even while under the effects of Novocain. Due to careful isolation of his brain from the growth, Pinon avoided any resulting brain damage, thus preserving his mental faculties.
