INTRODUCTION AND LITERATURE
Fetal mummification can result from disturbance at
the course of pregnancy, when fetal death is not associated
to microbian contaminations. The process o f mummifica­
tion carries reabsorption o f placentary liquids and, conse­
quently, involution o f fetal membranes, that stay adhered
to dried fetus (JUBB & K EN N EDY2, 1973).
Fetal mummification in dogs occurs after uterine trau­
matisms (SMITH4 , 1974), however, it is considered rare in
this species (ROBERTS3, 1971). On the other hand,
(SMITH4 , 1974) mentions the possibility of rupture o f ute­
rine wall consequent from dystocias, and at certain condi­
tions, it can have dislocation of fetus to the abdominal cavi­
ty. I f fetal circulation is maintained, with fetal death, it will
be possible that it suffers reabsorption or produces peritoni­
tis.
The purpose of this report is detain for lack of infor­
mation at veterinary literature about occurrence o f fetal
mummification at abdominal cavity in animals o f canine
species, associated to pyometra.
CLIN ICA L REPORT
M ASAO, I. Fetal mummification in a bitch with pyometra. Rev.
Fac.Med.vet.Zootec.UnivJS. Paulo, 18(2): 177-179, 1981.
S U M M A R Y : It is reported a case of a bitch presenting fetal m um m i­
fication in the abdominal cavity concomitant with pyometra, being
considered an uncommon finding at veterinary literature. The ani­
mal was treated surgically with absolute success.
UNITERMS: Bitch*; Fetal mummification*; Pyometra*.
Is was presented to clinical examination a mongrel
bitch 7 years old, multiparous, having the last pregnancy
occurred 2 years ago. At the two last months, the animal
showed, twice, vaginal discharge with bloody aspect, being
treated with antibiotic, till supression o f symptoms.
At clinical examination, it was verified an enlargement
o f the abdomen, bloody vaginal discharge, rectal temperatu­
re 39,3°C, congestive mucous membranes. At abdominal
touching, presence o f formation suggesting an enlargement
o f uterine horns and also inappetence. Hemogran revealed
leukocytosis (17.250/mm3), plasmatic degeneration o f neu­
trophils, monocytosis and increase o f young neutrophils.
Radiographic examinations o f abdominal cavity at lateral
(figure 1) and ventro-dorsal positions, and also excretory
urography technics revealed defined contour o f the uterus,
with enlargement occupying all the medium-caudal position
o f abdomen, and also the presence o f image o f round for­
mation, with heterogenous density, but suggesting esqueletic structure, situated at cranial-ventral region.
A clinical pyometra diagnosis was suggested, associa­
ted to probable presence o f mummified fetus in the abdo­
minal cavity. It was indicated surgical treatment, through
laparothomy, when is was verified pyometra associated to
the round formation at the adipose tissue o f epiplon.
It was realized ovariohysterectomy and excision of the
formation situated at the epiplon, having the animal presen­
ted favourable pos-operative evolution.
At the examination of the conjunct ovary-horn-uterus,
it was verified, at the wall of the uterus, point o f cicatricional retraction, with growth of adipose tissue (figure 2 ); the

DISCUSSION
IW ASAKl, M.
Estudo do aparelho urinário e de pa­
tologias abdominais em cães e gatos, mediante
emprego da urografia excretora.
This report points to found clinical setting extremaly
rare, because the fetal mummification refered by SMITH 4
(1974) only occurs in absence o f microbian contamination
(JUBB & K EN N ED Y 2, 1973) and it would be rare at the
canine species (RO BERT S^, 1971).
The mummified fetus was located in the abdominal ca­
vity, possibly since last pregnancy, having reached that site
through rupture o f uterine wall, according to cicatricial re­
action found in the uterus. Concomitantly, it was evidenced
presence o f pyometra that was suspected by radiologic exa­
mination through the technique o f excretory urography
(IW A S A K lI. 1977), that permited verification o f isolation
between formation involving mummified fetus and uterine
horns.
