So-called SMON is an abbreviation of subacute myelo-optico-neuropathy; that is an encephalo-myelitis accompanied with some abdominal symptom, which has been reported in Japan since 1957, and the patients are remarkably increasing in number recently. The causes of this disease being still unknown, each diagnosis depends upon its clinical figures, therefore it is not always easy to distinguish from other similar neuropathies. Kazuya Ando has noticed 17 clinical characteristics of SMON, among which he's pointed out 3 “dominant characteristics” and 5 “important ones”.
The case reported here concerns with a woman aged 42, who, suffering from caries of dorsal vertebrae, entered our hospital in 1948. Since she came here, she has also been attacked with various complications of tuberculosis and is still under medical care in the hospital. In 1960 she was attacked with severe abdominal pains, which was followed by the appearance of some serious neurological symptoms on the lower parts of her body, and she is now suffering from its following complaints. The diagnosis had been left unsettled for several years, and as the notion or SMON was proposed by specialists lately, the author noticed consequently that the clinical figures of this disease was quite similar to SMON. But one question on its differential diagnosis is left unanswered: the dysfunction of deep-sensibility in this case s not remarkable, which is considered as one of characteristic figures of SMON.
