Résumé:
The purpose of this study was to describe the clinical, laboratory, ultrasonographic, and
pathological findings of 30 adult cattle diagnosed with traumatic reticulo splenitis and five adult
cattle diagnosed with diaphragmatic reticular hernia attended et the Clínica de Bovinos de
Garanhuns of the Universidade Federal Rural de Pernambuco. All cattle underwent clinical and
ultrasound examinations. Blood samples were collected from all animals, into siliconized
vacutainer tubes containing EDTA anticoagulant (10%) to determine hematological variables
(blood count, total plasma protein, and plasma fibrinogen). Cattle whose prognosis was
unfavorable were euthanized and necropsied. Clinical, ultrasound, and anatomopathological
findings were analyzed using descriptive statistics and laboratory data were evaluated using
mean and standard deviation. Clinically the animals diagnosed with traumatic reticulo splenitis
presented dehydration and alterations in behavior, appetite, and ruminal motility.
Hematological findings revealed neutrophilic leukocytosis (37,077cell/μL) with regenerative
left shift and hiperfibrinogenemia (1,130mg/dL). The ultrasound examination enabled
visualization of fibrin adhesions, displacement of the reticulum and irregularity in its contour,
in addition alterations in the quantity, pattern, and amplitude of reticular contractions. It also
allowed to find splenic alterations such as abscesses, splenic venous thrombosis and spleen
bowed. Cattle affected with diaphragmatic reticular hernia exhibited varying degrees of
dehydration, abdominal distension, tympania and changes in ruminal motility. In addition to
cardiorespiratory changes such as heart murmur, dyspnea, and muffling of lung sounds.
Laboratory examination revealed mild neutrophilic leukocytosis and hyperfibrinogenemia. And
the ultrasound images revealed reticulum inside the thoracic cavity near the lung and heart, but
no reticular motility was observed. The anatomopathological lesions confirmed the imaging
findings for both diseases. Given the results we found that the ultrasound examination was
effective for the diagnosis of reticulum traumatic splenitis and diaphragmatic reticular hernia.
