ophthalmic examination of the right eye were within normal limits. Figure 1— Images in a computed tomography study of the head of a 12-year-old spayed female mixed-breed dog evaluated for exophthalmos of the left eye. Five-millimeter slices with 50
(black arrowheads). Figure 3— Axial computed tomographic image of the thorax. Notice the severe attenuation of the tracheal lumen (white arrow). Comments Because of the extent of tracheal occlusion observed via computed tomography, a
the caudodorsal aspect of the thoracic wall on the left side. Computed tomography of the thorax and abdomen ( Figure 3 ) was performed and revealed an elongated radiopaque foreign body in the stomach that extended through the dorsal aspect of the
ultrasonography were consistent with a mass lesion in the central retroperitoneal area. Computed tomography of the thoracolumbar portion of the vertebral column was performed ( Figure 1 ). Figure 1— Transverse computed tomographic image (A; slice thickness
/dL and similar to the serum creatinine concentration, which was measured concurrently. A fluid-filled cystic structure was observed caudal to the bladder on abdominal ultrasonography. A computed tomography scan of the abdomen was performed ( Figure 1
CBC and clotting profile were within the respective reference ranges. No abnormalities were detected on thoracic radiography. Computed tomography (CT) of the nasal passages was performed; precontrast and postcontrast images were obtained ( Figure 1
eighth left intercostal spaces revealed a heterogeneous, poorly echogenic linear structure separating the lung from the thoracic wall. Computed tomography of the thorax ( Figure 3 ) revealed an ovoid tissue structure with a density measurement of −90
arrowheads). There is deformation of the diaphragm where it contacts the mass (black arrows). On contrast-enhanced computed tomography ( Figure 3 ), a large rim-enhancing homogenous soft tissue density mass is evident in the caudal mediastinum
the spinal cord to the right (black arrowhead) and lysis of the left pedicle and body of T4 (white arrowhead). Postmyelographic computed tomography (CT) was performed to confirm the presence of an extradural mass and assess the degree of
