ENGLISH VERSION
We report the case of a 19 year-old male
paꢀent who sought medical care due to epigastric pain
and vomiꢀng. On physical examinaꢀon, he presented
epigastric tenderness on palpaꢀon. Blood amylase
level was 780 UI. An abdominal ultrasound showed
microscopic gallstones without choledocolithiasis.
The paꢀent conꢀnued with abdominal pain,
and as he developed a palpable tumor in the epigasꢀc
area, he underwent a computed tomography scan,
which showed a peripancreaꢀc cyst suggesꢀve of
pancreaꢀc pseudocyst (Fig. 1).
An abdominal magneꢀc resonance imaging
scan described the presence of a unilocular cysꢀc image
in the body and tail of the pancreas with a diameter
of 10 cm, corresponding to type I of the Nealon and
Walser classificaꢀon (Fig. 2). The paꢀent underwent
transgastric endoscopic drainage with stent implant.
The postoperaꢀve period was unevenꢂul and the
paꢀent was discharged 48 hours aꢃer the procedure.
Thirty days later, the paꢀent underwent laparascopic
cholecystectomy with intraoperaꢀve cholangiography.

locular cysꢀc image, with heterogeneous content is visible (arrow).
The cyst did not recur during the subsequent follow-up
visits.
Pancreaꢀc pseudocyst represents 13% of
pancreaꢀc cysts.
A pseudocyst more commonly
develops secondary to cholelithiasis, but may be also

It takes about 4 weeks for a pancreaꢀc pseudocyst
to develop. A pseudocyst with a size > 5 cm or that
persists for a longer period of ꢀme has less chance
of spontaneous resoluꢀon and greater possibility of

management in asymptomaꢀc cases independently of
its size. Thus, management of pancreaꢀc pseudocyts is
controversial 3 and includes percutaneous, endoscopic
or surgical drainage. The evidence supporꢀng one
method or another is scarce and the approach selected
depends on each paꢀent.
Percutaneous drainage is useful in infected
pseudocysts or in the presence of symptoms of
