However, Gurd and Wilsons criteria for fat embolism become more commonly used when compared to the other two diagnostic criteria. Gurd and Wilsons criteria
Major criteria
Axillary or subconjunctival petechiae
Hypoxaemia PaO2 <60 mm Hg, FIO2 = 0.4
Central nervous system depression disproportionate to hypoxaemia
Pulmonary oedemaMinor criteria
Tachycardia more than 110 beats per minute
Pyrexia more than 38.5 °C
Fat globules present in urine
Changes in renal function (reduced urine output)
Drop in haemoglobin values (more than 20% of the value upon admission)
Drop in haematocrit values
Drop in platelet values (more than 50% of the value upon admission)
Increasing erythrocyte sedimentation rate (ESR) (greater than 71 mm per hour)
Fat globules present in the sputum
Emboli present in the retina on fundoscopyA least two positive major criteria plus one minor criteria or four positive minor criteria are suggestive of fat embolism syndrome. Fat embolism syndrome is a clinical diagnosis. There are no laboratory tests sensitive or specific enough to diagnose FES. Such laboratory tests are only used to support the clinical diagnosis only. Chest X-ray may show diffuse interstitial infiltrates while chest CT scan will show diffuse vascular congestion and pulmonary oedema. Bronchoalveolar lavage has been proposed to look for fat droplets in alveolar macrophages however it is time-consuming and is not specific to fat embolism syndrome. Looking for fat globules in sputum and urine is also not specific enough to diagnose FES. Prevention
For those treated conservatively with immobilisation of long bone fractures, the incidence of FES  is 22%.
The epoophoron or epoöphoron (also called organ of Rosenmüller or the parovarium) is a remnant of the mesonephric tubules that can be found  next to the ovary and fallopian tube. Anatomy
It may contain 10–15 transverse small ducts or tubules that lead to the Gartner’s duct (also longitudinal duct of epoophoron) that represents the caudal remnant of the mesonephric duct and  passes through the broad ligament and the lateral wall of the cervix and vagina. The epoophoron is a homologue to the epididymis in the male. While the epoophoron is located in the lateral portion of the mesosalpinx and mesovarium, the paroophoron (residual remnant of that part of the mesonephric duct that forms the paradidymis in the male) lies more medially in the mesosalpinx. Histology
It has a unique histological profile. Clinical significance
Clinically the organ may give rise to a local paraovarian cyst or adenoma. See also
