Pancreatic pseudocysts are focal fluid collections that develop as a result of inflammatory diseases of the pancreas. They are managed conservatively or with a drainage procedure. Their radiological appearance can mimic cystic neoplasms of the pancreas. Pancreatic cystic neoplasms include various neoplasms with a wide range of malignant potential. Here, we report a patient with a pancreatic pseudocyst that presented with macrocystic attributes on endoscopic ultrasound.

The decision of surgical treatment for pancreatic cystic lesions may mainly depend on the malignant potential of each lesion. Surgical excision is the most optimal treatment for the mucinous cystic neoplasm due to its high malignant potential. On the other hand, intraductal papillary mucinous neoplasm (IPMN) is divided into main duct type and branch-duct type. Main duct IPMN has high risk of malignant transformation. Therefore, surgical resection has been recommended for all main duct IPMN. Branch duct IPMN has relatively low malignant potential, and usually shows slow progression. A branch duct IPMN that is asymptomatic, less than 3 cm in size and without mural nodules may be followed-up without resection. Serous cystic neoplasm is usually benign in nature. Surgical treatment for serous cystic neoplasm should be considered when definitive diagnosis being uncertain, larger than 4 cm in size, or presence of symptoms. Solid pseudopapillary neoplasm also has low malignant potential which needs surgical excision. Surgical treatment for pancreatic pseudocyst is considered in limited cases with complication, such as infection or bleeding, and which is not controlled with non-surgical treatment. Management strategy for pancreatic cystic lesions should be individualized, and the decision to resect or follow-up a lesion should be based on factors such as the presence or absence of symptoms, patient age, cyst size, grading of malignant potential, location of the lesion, and the surgical risk of the patient.

Pancreatic cystic lesions include retention cysts (congenital cysts), pseudocysts, and cystic neoplasms. Pancreatic cystic neoplasms have recently been diagnosed more commonly, possibly due to advances in imaging and widespread screening programs. Cystic neoplasms of the pancreas account for 10-20% of pancreatic tumors. Mucinous cystic neoplasms (MCN) and intraductal papillary mucinous neoplasms are regarded as premalignant lesions, whereas serous cystadenoma is not. In the clinical setting of acute pancreatitis, pancreatic cystic lesions are usually diagnosed as pseudocysts. However, cystic neoplasms of the pancreas should be considered in the differential diagnosis of pancreatic cysts, even in patients with a history of pancreatitis. In the Korean literature, MCN combined with acute pancreatitis has rarely been reported. Here, we report a case of MCN presenting with acute pancreatitis in a 22-year-old female, which was initially misdiagnosed as pancreatic pseudocyst.

Lymphangiomas are rare congenital benign tumors arising from the lymphatic system, and are mostly encountered in the neck and axillary regions of pediatric patients (95%). Lymphangioma of the pancreas is extremely rare accounting for less than 1% of these tumors. We report here on a case of pancreatic cystic lymphangioma. A 54-year-old woman presented with intermittent postprandial abdominal discomfort and radiating back pain. Abdominal computed tomography scan revealed 8 x 6.5 cm hypodense cystic mass arising from the tail of the pancreas without septa or solid component. The initial impression was a pancreatic pseudocyst. The patient underwent distal pancreatectomy with splenectomy. The histopathologic and immunohistochemical study helped make the diagnosis of a pancreatic cystic lymphangioma. Herein, we report a case of pancreatic cystic lymphangioma mimicking pancreatic pseudocyst and review the relevant medical literature.

The incidence of acute cholecystitis complicating endoscopic retrograde Cholangiopancreatography (ERCP) is rarely reported at 0.2% but is usually associated with a cystic duct obstruction caused by gallstones, gallbladder polyps, or cancer. However, acute cholecystitis with a gallbladder perforation after ERCP without a history of cystic duct obstruction can develop very rarely and has not yet been reported in Korea. We report a case of acute cholecystitis with gallbladder perforation and aggravation of a pancreatic pseudocyst after diagnostic ERCP in a man with a pancreatic cystic lesion. He has been successfully cured using only percutaneous transhepatic gallbladder drainage and antibiotics with no surgery.

BACKGROUND: Pancreatitis is uncommon in childhood and there is presently no study among Filipino children.

OBJECTIVE: To determine the clinical features and outcome of pancreatitis among Filipino children.

METHOD: Review of medical records of all patients diagnosed to have pancreatitis based on standard criteria from 2005 to 2009.

RESULTS: A total of 23 children (mean age: 12 years; 13 male, 10 female) were included, 21 with acute and two with chronic pancreatitis. Twenty one (91%) presented with abdominal pain and two with jaundice. Nine had idiopathic pancreatitis. In 14 patients, the etiology was identified: bile duct obstruction (7), trauma (2), drugs (2), infection (2) and hypertriglyceridemia (1). Only four of 20 patients with ultrasound examination showed an enlarged pancreas. Complications were pseudocyst formation (6), pancreatic abscess (4), diabetes mellitus (2) and hypocalcemia (1). Of the 23 patients, eight required surgery: pancreatic debridement (4), choledochal cyst excision (2), cholecystectomy (1) and Whipple's procedure (1). All pseudocyst resolved spontaneously. One patient with pancreatic tumor declined surgery and another with pancreatitis due to choledochal cyst died of sepsis.

CONCLUSIONS: In our study, severe abdominal pain was the most frequent presenting symptom of childhood pancreatitis. Sixty percent had an identifiable cause for pancreatitis. A favorable outcome was observed.

A pseudocyst, one of the most prominent and definitive signs of pancreatitis, can also be cause by pancreatic carcinoma. However, a pancreas carcinoma and pancreatitis are sometimes indistinguishable. Reports of a pancreatic carcinoma coexisting with pancreatitis and a pseudocyst are rare. We have experienced a case of a pancreatic carcinoma, which was misdiagnosed as chronic pancreatitis with a pseudocyst. A 31-year-old man complaining of an epigastric pain visited our hospital. Ultrasonography (US) and computed tomography (CT) revealed two cystic lesions, about 8 and 2 cm in diameter, splenic vein thrombosis and diffuse inflammatory changes in the pancreatic body and tail. The value of the tumor marker, CA19-9, was 132 U/ml. Chronic pancreatitis with pseudocyst was suspected, and a cystogastostomy and splenectomy performed. A histological examination revealed a pancreatic pseudocyst. The patient was readmitted 7 months later due to abdominal pain. The serum CA19-9 level was 544 U/ml. The CT revealed severe diffuse inflammatory changes in the pancreatic body and tail. Percutaneous CT- guided fine-needle aspiration revealed a pancreatic adenocarcinoma. The differentiation between the pseudocyst of pancreatitis and the secondary cyst caused by a pancreatic carcinoma is important but is difficult or impossible in some cases. The CT features of pseudocysts secondary to a pancreatic carcinoma are identical to those of pseudocysts in pancreatitis. Even in retrospect, our case was difficult to differentiate from pancreatitis with pseudocysts. Our results indicate that whenever pancreatic cysts are encountered in patients with unusual presentation, further examinations, including percutaneous aspiration biopsies, should be performed to exclude malignancy.

Congenital pancreatic cysts are rare in newborn babies, and this makes prenatal diagnosis difficult. Diagnosis can be delayed for a few months after birth until the infant presents with an abdominal mass, abdominal distension, or vomiting due to gastric outlet obstruction. Excision of the cyst is the treatment of choice. A congenital pancreatic cyst should be considered if the fetus has an abdominal cyst without a definite origin. A prompt diagnosis is crucial to prevent fatal complications such as cholangitis, pancreatitis, cyst rupture, and peritonitis. We report a case of neonate with multiple congenital pancreatic cysts suspected prenatally to be stomach diverticulum or duplication cysts of the intestine.

The most common pancreatic cystic lesion is pancreatic pseudocyst which represents about 85%. Primary cystic neoplasms represent about 10 to 15% of the lesion. Pathologically cystic neoplasms can be classified into serous cystadenoma, mucinous cystadenoma and papillary cystic neoplasm by epithelial lining-cell, whereas pseudocyst is characterized by fibrotic capsules. Mucinous form is known to be premalignant or malignant and serous cystadenoma was known to be benign in the past, but recently 4 cases of malignant transformation have been reported. Serous cystadenoma is described under a variety of names, including microcystic adenoma and glycogen-rich cystadenoma but recently macroqystic variants have been reported. Serous cystadenoma is most commonly seen in middle aged women with symptoms of vague upper abdominal pain or palpable mass. It is sometimes associated with extra- pancreatic diseases such as gallstones, diabetes mellitus, hypertension, duodenal ulcers, sterility, obesity and thymic dysfunction, but coexisting papillary thyroid cancer have been reported in only 2 cases to our knowledge. The pathogenesis of associated diseases is unknown and appears to be due to function of age of the patients or incidental occurrence. Herein, we report a patient who had a pancreatic serous cystadenoma coexisting with papillary thyroid cancer. Since pancreatic serous cystadenoma can occur in association with papaillary thyroid cancer, examination of thyroid seems to be advisable when pancreatic serous cystadenoma is found.

Cystic lesions of the pancreas have been detected more frequently than before because of the development of imaging technologies. Pancreas cysts can be divided into neoplastic or non-neoplastic and neoplastic cyst can be categorized as potentially malignant or non-malignant. Cystic lesion that contains mucinous material has malignant potential. Some factors that can predict the presence of malignant tissue has been identified. Serous neoplasm, congenital cysts and pseudocyst do not have malignant potential. Solid pseudopapillary tumor or endocrine tumor can undergo cystic degeneration and also have malignant potential of low level.
