ENORMOUS HEMATOMA PRODUCED BY THE RUPTURE OF THE LEFT 
MAMMARY VEIN IN A COW.—RECOVERY. 
By M. Lambert. 
/ 
The subject of this case is a cow eleven years old. While she 
returned from pasture, after drinking from a trough placed near a 
well close by, she appeared in perfect health. After being a few 
minutes in the barn an enormous tumor was observed on the left 
side of the abdomen, extending from the mammae to the middle 
of the belly. 
When visited, she was found in a comatose condition, with 
tremblings of the crural muscles; pulse small and frequent (80); 
visible mucous membranes pale. The tumor had an irregular 
form, measuring 68 centimetres in length, 18 centimetres in 
thickness, extending backwards up the left flank, and diminishing 
forward, gradually ending in a triangular shape. The tempera¬ 
ture of the skin was normal. The tumor was resisting to pres¬ 
sure, but pitting at some points. It was not painful to the touch 
and was normal in color, except at some points where it showed 
ecchymotic spots. Kectal examination revealed ventral hernia. 
The diagnosis was at flrst uncertain. 
The day following there was anorexia; pulse small and weak 
(00); rumination stopped; milky secretion diminished; defeca¬ 
tion normal. Ihe swelling had increased and extended to the 
light side. Ihe skin of the left side had become sensitive from 
frictions with liniment, applied the day before. Upon explora¬ 
tion with a tine trocar a strong stream of venous blood made its 
appearance. An incision of one centimetre gave rise to an abund¬ 
ant hemorrhage, which had to be stopped, checked with pads of 
oakum pressed into the wound. An examination of the mammary 
veins showed that of the left side depressed or flattened, while 
that of the right had not lost its natural prominence. The diag¬ 
nosis was that of a rupture of the vein, taking into account the 
considerable size and rapid development of the tumor, the stream 
of mucous and blood following the exploration with the trocar, 
the presence of an ecchymosis on the surface of the swelling, the 
pale condition of the visible mucous membranes and the symp¬ 
toms of the left mammary vein ; the cause of the accident was 
not made out.
