The uterus is usually displaced by the exudation to an extent depending upon the size of the swelling, to which it is fixed more or less firmly. If the effusion has taken place in one of the broad ligaments, the organ will be displaced to the opposite side, but if the inflammatory process has extended to the cellular tissue in the posterior region of the cervix and in the utero-sacral ligaments, the organ may be displaced forward as well as laterally. If the cellular space between the bladder and cervix alone be involved in the inflammation, the resulting effusion may displace the uterus backward, but the disease is rarely met with in this location. Retroversion of the uterus frequently complicates parametritis, but in that case the abnormal position is not necessarily due to displacement by the exudation. It may have existed previous to the attack. It must not be forgotten, however, that the symptoms and physical signs, as described above, apply only to the acute form of the disease, and that they do not exist in the same degree nor in the same regular order when the inflammatory process has been subacute, as it often is, from its commencement. When the disease is subacute from the start, the patient may be enabled to go about, and even to pursue a laborious occupation, but not without suffering. There will always be more or less pain experienced in the affected region, and the temperature and pulse will be slightly increased. In rare cases the manifestations of the disease may be so slight or so little complained of that the physician is surprised to find, on examination, a large exudation in one or both broad ligaments. DIFFERENTIAL DIAGNOSIS.--It is of the greatest importance that this disease should be recognized early, so that prompt measures may be taken to arrest it if possible, or at least to modify the severity of its course. Fortunately, as a rule, the subjective symptoms of pelvic inflammation are so marked that the attention is at once directed toward seeking for their confirmation by eliciting the physical signs; and for diagnosis these local manifestations of the inflammatory process are to be relied upon entirely, as the subjective symptoms of inflammation of the other tissues and organs of the pelvis somewhat resemble those of parametritis. The diseases the local signs of which approach more nearly those of parametritis are--pelvic hæmatocele, fibrous tumor, the early stage of extra-uterine pregnancy, the early stage of parovarian and ovarian cystic degeneration, and perityphlitis.
