wall cyst having incomplete septation & low level echoes (32x26x6)mm is
noted in right pelvic cavity near urinary bladder.
Then patient got admitted under Department of Pediatric Surgery
Birdem General Hospital (Mohila O Shisu) for further management..

mobile lump in right lower abdomen.

12. PROVISIONAL DIAGNOSIS

13. Provisional diagnosis
Mesenteric cyst

14. Differential Diagnosis

15. Differential Diagnosis
 Cystic teratoma
 Omental cyst
 Hydatid cyst

16. USG of Whole Abdomen
A well defined cystic area with thick wall
margin with multiple thick septations with
internal echogenic debris in the right
lower abdomen measuring (3.5x3)cm
Comment: Multisepted thick wall cystic
lesion in right lower abdomen and right
ilac fossa.Possibility of mesenteric cyst

17. CT scan Whole Abdomen

18. Cont’d..
 Findings: A cystic lesion about (3.1x3.1x3)cm at the interface of right
lumber and iliac fossa region. The lesion is showing mildly thick wall
measuring about 2.8 to 3 mm. Few internal septation’s are observed
within the lesion. Interrupted calcifications are seen in the wall of lesion.
Post contrast scan revealed minimal marginal and internal septal
enhancement of the lesion.
 Comment: Possibility of Mesenteric cyst of right lumber and iliac fossa.

19. Chest X-Ray P/A View
Comment: Normal study

21. Clinical diagnosis
Mesenteric cyst

22. Management
 Counseling of parents for treatment options.
 Preanaesthetic checkup
 Informed written consent was taken.

23. Operation note
 Name of operation: Excision of mesenteric cyst
 Indication: Mesenteric cyst
 Anesthesia: G/A
 Patients position : Patient was placed in supine position.
 Incision: A transverse incision made on right lower abdomen

24. Cont’d
After entering peritoneal cavity, an
intact cyst (Type-1) was exteriorized
which was arising from the terminal
ileal mesentery. Intra-operative image
showed the intact cyst size about
(3.5x3)cm

25. Operation note (Cont’d..)
 The cyst was excised in toto. The
rest of the bowel was splayed around
it and was healthy. Abdomen was
closed in layers.

26. Operation note ( Cont’d..)
 On cutting it open, it was filled with
whitish fluid.

27. Final diagnosis
Mesenteric cyst-Type 1

28. Post-operative period
Post-operative period was uneventful.
He was discharged on 4th postoperative day with advice for follow up
after 7 days with histopathology report.

29. Histopathology
Microscopic description:
 Cut sections show cyst wall composed of fibromuscular tissue.
 Focal area is lined by tall columnar epithelium. Subepithelial tissue is
infiltrated by acute and chronic inflammatory cells.
 No granuloma or malignancy seen.

30. Follow up
 No complaints
 Bowel and bladder habit was normal
 On examination
 Abdomen-soft, non tender
 Wound- healthy

31. Take Home Messages
 In asymptomatic cases early surgery advised to avoid acute abdominal
catastrophic like cyst hemorrhage, rupture,volvulus etc..
 Meticulous surgery needed to avoid gut injury and recurrence.

32. Thanks all

33. Short discussion
A mesenteric cyst is formed of fluid collection between the two layers
of small bowel mesentery.
Types and etiology
Chylolymphatic cyst.
 Enterogenous cyst.
 Dermoid cyst.
 Cyst of urogenital remnants.

34. Presentation
• Mesenteric cyst mostly discovered incidentally.
• Symptoms
Abdominal distension
Abdominal pain
Mass may be palpable
Approximately 10% of patients with mesenteric cyst present with
an acute abdominal emergency, the most common picture is small
bowel obstruction.

35. Treatment
• Enucleation:The preferred treatment of mesenteric cyst
of chylolymphatic origin.
• Excision and intestinal ressention is frequently required to ensure that
the remaining bowel is viable
• Partial excision with marsupialization If enucleation or resection is not
possible because of the size of cyst or because of it’s location deep
within the root of mesentery

36. CONT.
• Laparascopic management: Could be used to localize the cyst
and resection could be performed through a small laparatomy or via
an extended umbillical incision.
• Ultrasound guided drainage has also reported to be successful.
