Background: Cranioschisis is a malformation that occurs during embryological development and results in incomplete closure of the skull, leaving an opening through which the intracranial tissue can project. Meningocele consists of herniation of the meninges containing cerebrospinal fluid through the cranial defect. In cattle, this association usually manifested by the appearance of a floating saccular protrusion of variable size and volume in the frontal or parietal region of the cranium. This manuscript aims to report a case of cranioschisis associated with meningocele and neurological deficit in a newborn calf in the northwestern region of the state of Paraná. Case: A 2-day-old crossbred female calf was diagnosed with cranioschisis associated with meningocele in the frontal region of the head. On initial clinical examination, an ovoid mass with floating appearance was observed, extending from the supraorbital curvature of the frontal bone to the end of the nasal bones following the midline. The patient had normal parameters for the species and age and a positive sucking reflex. Neurological examination showed permanent lateral decubitus position, spastic paresis of the thoracic limbs and opisthotonus. Complementary imaging studies, including xrays and ultrasonography, showed a failure in the frontal bone, approximately 5 cm in diameter. Despite the unfavorable prognosis, surgical reduction was chosen. After drainage of the cerebrospinal fluid, excision of the meningeal sac was continuously performed, exposing the subarachnoid space, showing circular failure in the frontal bone with a diameter of 4.5 cm, making it possible to observe part of the right frontal lobe. We opted for occlusion of the bone defect by covering it with the dura mater. Absorbable 0 catgut suture was applied in a simple...(AU)
