522 Diseases of Joints. 



On dissection, the body was found to be much emaciated. There 

 was serum in both pleurae, and in the pericardium, but the lungs were 

 healthy. A tumour of the size of an egg projected from the spine into the 

 left pleura. It consisted of a very soft sac, filled with curd-like matter. 

 On examining the spine more minutely, it appeared that the last cervical 

 vertebra was slightly carious, and that the bodies of the three uppermost 

 dorsal vertebrte had been almost wholly absorbed." 



Almost the whole of the bodies of the first two dorsal vertebra; 



have disappeared. The debris of caseous material and bone — 



removed by maceration- — has no doubt been pressed back upon 



the spinal cord by the weight of the head and neck. The right 



pedicle and lamina of the first dorsal vertebra have disappeared. 



Parts of the next two vertebrse on the same side are rarefied. 



Elsewhere the laminae, as well as the spines, do not seem to 



have been affected. G. C. 1288.

7. 232. Tubercular Disease, with Destruction of Bodies, 



Abscess, Parapleg'ia. — Left half of the lower cervical 

 and upper dorsal vertebrae of a boy— in spirit, illustrating the 

 above. 



The patient, aged 12 years, was admitted to the Royal Infirmary, 

 Edinburgh, on 17th October 1892. He had been treated for disease of 

 the spine, with jackets, etc., since the age of four. He was admitted on 

 account of partial paralysis of motion and sensation of the lower limbs, 

 occasional involuntary passage of urine, exaggerated knee-jerk and ankle 

 clonus, but with no fever. There was a marked angular curvature in the 

 cervico-dorsal segment of the spine. Double eitension was applied to 

 the head and lower limbs for six weeks without improvement. In 

 December 1892 Professor Annandale removed the lamina and spines 

 of the seventh cervical and first and second dorsal vertebra;. Pus iu 

 abundance, welled up between the dura and the canal, evidently coming 

 from the situation of the bodies in front. The patient, however, died on 

 the same night from respiratory embarrassment and shock. 



At the jwst-inorfem examination firm adhesions were found at the 

 right apex of the lung, but no tubercular or waxy disease of any of the- 

 organs. A large caseous abscess lay in front of the bodies, corresponding 

 to the curvature. The diseased segment was removed, and after being 

 frozen was sawn in sagittal mesial section. 



The specimen shows great destruction and absorption 

 of the bodies of the lower cervical vertebrse, with a correspond-
