Sixteen cases of thoracic radiculomyelopathy due to ossification of the ligamentum flavum (OLF) were analyzed. The patients ranged in age from 39 to 78 years (average 57 years). There were 13 men and 3 women. A significant predilection of OLF for the lower thoracic spine (T9/10, T10/11, T11/12) was noticed. Plain X-ray of the thoracic spine and multidirectional tomography could give important information about the site of ossification. Computed tomography with the intrathecal injection of the water-soluble contrast material clearly demonstrated the ossification and the degree of compression of the spinal cord. The disadvantages of using computed tomography for diagnosing OLF included the necessity for the scan level to be previously decided by other methods because computed tomography of the entire spine was impractical. Magnetic resonance imaging was performed in 14 patients and gave important information about OLF and the compression of the spinal cord. The combination of MRI and computed tomography seems the most useful for the precise diagnosis of OLF.

In this case, the changes noted were interpreted as changes showing fragility of the vascular wall secondary to neurofibromatosis Type 1. Patients with neurofibromatosis Type 1 exhibit disorders of cervicocerebral vessels, and in some cases progression may follow a violent course. Periodic follow-up of such patients and early diagnosis are important.

This report presents the case of an 84-year-old woman who developed tetanus 3 days after the resection of a gangrenous small intestine caused by obturator hernia incarceration. The diagnosis of tetanus was clinically made after the appearance of generalized spastic contractions with opisthotonus. Clostridium tetani organisms residing in the gastrointestinal tract were presumed to have been endogenously inoculated into the strangulated intestine, where it produced tetanospasmin, causing tetanus. The patient successfully recovered after aggressive intensive care. There have been 16 case reports of tetanus occurring after gastrointestinal surgical procedures. Primary care physicians should thus be aware of the fact that, although extremely rare, C. tetani residing in the gastrointestinal tract can provide a possible endogenous source of tetanus infection.
