The pain was located to the abdomen.Her vital signs were non-reassuring.A mass was palpated arising from the pelvis on the left side.Her medical history included aleft oophorectomy due to a cyst form about 13 centimeters. The tumor makers were within normal range. Moreover, an abdominal MRI scan was carried out, that described the presence of a cyst measured 10 x 8 cm in the left parametrium.She was scheduled for surgery a few days later. The cyst was above the division of iliac vessels cling to left ureter and left uterine artery. The operation was uncomplicated and her post-operative period was uneventful. Histology showed lymphocyst, without any signs of malignancyFifteen days later after a routine check, an entrenched retention of fluid was found in the pouch of Douglas 5 cm which was aspirated by needle under guidance of Computed Tomografy. The cytological examination showed lymphpocytes as an inflammatory response.Results In 5 to 10% of patients, the lymphocyst become symptomatic, manifesting fever, pain, constipation, prolonged ileus, urinary frequency, obstructive uropathy, leg edema, erythema of overlying skin or deep vein thrombosis.Conclusion Most lymphocysts are asymptomatic and are only diagnosed accidentally. A symptomatic lymphocyst may compress adjacent structures, for example, ureter, the urinary bladder, rectum or the iliac vein. Pelvic lymphocysts may be treated conservatively or surgically, by laparoscopy or laparotomy as well as using the methods of intervention radiology.Disclosure Nothing to disclose
