Evidence of Cushing's syndrome in a pre-Columbian Mexican statue?

In the absence of skeletons or written narrations, information about diseases in past societies may be acquired from icono-diagnosis. From the observation of a masterpiece presenting pathological features, we tried to make retrospective diagnosis.

A pre-Columbian Mexican statuette originating from the Chupicuaro culture and dated 600 BC to 200 AD - conserved in the Louvre Museum in Paris (Section of the quai Branly - Jacques Chirac museum) was examined; it was found to display a huge spinal curvature with excessive dorsal kyphosis and obesity.

The appearance of the figurine with large head, shortened stature and limbs, may suggest a form of dwarfism; however, many statuettes in the Chupicuaro culture were found displaying large head and relatively short limbs, suggesting that these pictorial features are more of an artistic style. On the contrary, uncommon kyphosis and obesity led us to diagnose a case of either Pott disease associated with neuro-endocrine complications, or of Cushing's disease.

Although icono-diagnosis could have allowed us to contribute to the health mapping of ancient Americas and propose the presence of complicated tuberculosis in central Mexico between 600 BC and 200 AD, we believe "Choupi" portrays here an individual having suffered from hypercortisolism (Cushing's disease). Even though considerations related to cultural and artistic context may constitute limitations to interpretation, iconotopsy/iconodiagnosis are important for a better description of the natural history of diseases, as a complement to morphological analyses of human remains (paleopathology) and laboratory exams (DNA or immunology testing).
