Female pelvi-abdominal multilocular recurrent fluid collection of uncertain aetiology.
Recurrent pelvi-abdominal multilocular fluid collections in female patients may be of various aetiology: infections, haemorrhage, benign or malignant tumours.


OBJECTIVE
Diagnosis of such fluid collections is complex, imaging examinations (ultrasonography, computed tomography, MRI) and biochemical, cytological and histological examinations must be included. Some cases, however, are difficult to diagnose, and their treatment is uncertain.


METHODS
We present the case of a 22-year-old unmarried female patient with minor symptoms, not correlated with a pelvi-peritoneal fluid collection extending into the infra-mesocolic space, revealed by ultrasonography and MRI. The aetiology was uncertain after biological examinations and cytology. The disease course was recurrent during 14 months, under anti-inflammatory treatment and surgical intervention with removal of the fluid (2.5 l), resection of the right ovary (histological examination revealed small ovarian mucinous cysts) and excision of a fibroma of the right utero-sacral ligament. Follow-up sonography was the chosen method for repeated diagnostic and therapeutic echo-guided punctures. Finally, after immuno-stimulating treatment, we observed almost complete remission of the peritoneal fluid collection.


RESULTS
This paper reveals significant discordances between the clinical appearance and the presence of a large peritoneal fluid collection, between locally recurrent appearance and cytological and histopathological "benign" results, between positive intradermal reaction to tuberculin and negative culture of B. Koch from aspirate. There were concordances between immune electrophoresis and some cytological elements and between three dimensional and panoramic SieScape ultrasonography and MRI. We must, however, note the superiority of MRI in the designation of anatomical findings and analysis of the histological structure.


CONCLUSIONS
The importance of this case is derived from the atypical clinical appearance and course, with uncertain aetiology after complex imaging, biological and surgical explorations.
