September, 1909 FIG. 6. The region of the pelvis of the case shown in Fig. 5. An attempt to introduce a wire into the ureteral catheter in situ was only partly successful. The wire is shown by the curved black line extending up and to the right from the symphysis pubis at lower part of cut. Above the shadow of the wire the course of the catheter is shown by a faint streak which is the shadow of the silver solution in the tube. In the upper part of the plate to the right of spine is shown the lower part of the dilated portion of the ureter. JOURNAL OF MEDICINE FIG. 7.-Frontal sinusitis. The cut is a reproduction of the X-ray plate or negative. (The preceding cuts are positives.) The region from just above the frontal sinuses to the lower part of superior maxillæ is included within the black mat or border. The two dark circular shadows near middle of cut show the orbits. Extending upward and outward across these are darker streaks outlining the sphenoidal fissures. Above the orbits are shown the frontal sinuses which in this case are unusually large. The median septum is deflected to the right and forms the boundary of the diseased right frontal sinus. The air space of the left frontal sinus, which is normal, shows in the negative as a darker shadow than that of the right frontal which is filled with fluid. The shadows of the anterior ethmoid cells show just below the frontal sinuses, and appear normal. The shadow of the left maxillary sinus is dark because of the normal air space, while the cloudy shadow of the right maxillary sinus indicates that it contains fluid. The turbinate bones of the left side give light shadows, and the small, dark circular area just to the right of the nasal septum at lower part of the cut, shows that the right inferior turbinate has been removed. |
