Patient 42 yo, labor of the load of bread, one  month ago  complaint by  periumbilical pain crisis.durring 1-2  minutes, no  fever  no  diarrhea,   more and  more frequent.
Ultrasound  abdomen  first time detected  free fluid ascitis in  large amount of volume  but unknown origine (see  ultrasound  images).
Gastroendoscopy showed gastritis with  negative HP test,
MSCT no CE also made sure this  liver  no cirrhosis and ascitis unknown origine.
Blood test report = WBC  rising.
What is your  diagnosis for the case and what do you do next ? 
Ultrasound guided punction of ascitis which was removed the yellowish  clear fluid  and biochemistry and cytology analysis.
RECENTLY LAB  REPORT of  BLOOD TEST from THIS PATIENT.
DISCUSSION:
 This case  was represented
unknown  ascitis  at first
 time by  ultrasound and CT scan, and blood test  report was  eosinophil  rising  too much,  43%, that many doctors were looking for a  parasite infected cause.
But, ascitis
 analysis was  transudate fluid  and hypoalbumine,   while
 CA125  was very high, of 1380 UI/mL 
in the male patient. So it was  difficult to explain that.
Cytology of
 ascitis fluid  showed  that
 many  white blood cells  of
eosinophil  in  one staining microscopic
champ.
Second report  of
blood test today  ruled out parasite infection, but IgE very high,  of  1168 UI/mL, that  suggested an  eosinophylic
gastroenteritis.
For  review and
 make sure  this  diagnosis, an other  ultrasound scanning
of  abdomen perfomed  to  detect   thickening of  intestine wall.  And  cytology  smear of ascitis
 fluid  was more eosinophil cells. 
A course of  corticotherapy was started today. Wait for
 clinical response.
After 2 days treatment with 50mg prednisolone, the blood test spectacularly responsed.
Today 9/9/2014
Update case 272:  After one week treated with corticoid,  clinical status of the patient remains well in recovery.
Ultrasound of abdomen  shows  completetly  dissapearing ascitis  ans blood test returns  nearly to  normal values ( see 2 ultrasound images, and blood test report).
