Abdominal hydatid cyst disease mostly involves the liver. Involvement of the pancreas as an isolated primary organ is rare accounting for < 2% of all systemic echinococcosis cases. It mostly involves the head of the pancreas. Symptoms depend on the location, size, and associated complications; therefore, it can have varied presentations including acute pancreatitis. On imaging, it can mimic other common pancreatic cystic lesions like pseudocyst or cystic neoplasm. Accurate preoperative diagnosis is usually difficult and requires a very high index of suspicion even in endemic areas. Herein, a case of primary isolated hydatid cyst of the pancreas that was initially diagnosed and managed as acute pancreatic pseudocyst is reported.

An 8-year old castrated domestic long-hair cat was presented with a two week history of abdominal distension. Physical examination revealed a non-painful, fluctuant, palpable mass in the right craniodorsal abdomen, and unilaterally muffled heart sounds on the right thorax. Routine clinico-pathological values were unremarkable apart from mild azotemia with a concurrent urine specific gravity of 1.031, which reflect a degree of renal dysfunction. Radiographic and ultrasound examinations of the thorax revealed the cardiac enlargement to be due to the congenital peritoneo-pericardial diaphragmatic hernia with liver occupying the right half of the pericardial sac. There was also a mild gypertrophy of the heart. Radiography and ultrasonography of the abdomen showed the mass to be composed of a large fluid filled cystic structures surrounding the right and left kidneys, and the kidneys themselves were of increased echogenecity. A diagnosis of perinephric pseudocysts was made. The patient responded well to the surgical procedures. Perinephric pseudocysts and peritoneo-pericardial diaphragmatic hernia in the cat are rare, and a case is described and the literature is reviewed in this report.

An urinoma(uriniferous pseudocyst, pararenal pseudocyst) denotes an encapsulated collection of urine in the perirenal or paraureteral space. It was usually reported in relation to trauma and acquired obstructive uropathy but rarely reported in renal infection including renal candidiasis. The mechanism is believed due to rupture of fornix through weakened portion of suppurated kidney and pyelosinus backflow by increased intrapelvic pressure in obstructive uropathy and fungus ball obstruction. We report a case of urinoma in a premature as the first case in Korea which developed as a complication of renal candidiasis.

Objective: The objectives of this study were to determine the frequency of symptomatic postdiscectomy pseudocyst (PP) after endoscopic discectomy and to compare the results of surgical and conservative management of them. Methods: Initial study participants were 1,503 cases (1,406 patients) receiving endoscopic lumbar discectomy by 23-member board of neurosurgeons from March 2003 to October 2008. All patients' postoperative magnetic resonance imaging (MRI) scans were evaluated. On the postoperative MRI, cystic lesion of T2W high and T1W low at discectomy site was regarded as PP. Reviews of medical records and radiological findings were done. The PP patients were divided into two groups, surgical and conservative management by treatment modality after PP detection. We compared the results of the two groups using the visual analogue scale (VAS) for low back pain (LBP), VAS for leg pain (LP) and the Oswestry disability index (ODI). Results: Among 1,503 cases of all male soldiers, the MRls showed that pseudocysts formed in 15 patients, about 1.0% of the initial cases. The mean postoperative interval from surgery to PP detection was 53.7 days. Interlaminar approach was correlated with PP formation compared with transforaminal approach. (p=0.001).The mean VAS for LBP and LP in the surgical group improved from 6.5 and 4.8 to 2.0 and 2.3, respectively. The mean VAS for LBP and LP in the conservative group improved from 4.4 and 4.4 to 3.9 and 2.3, respectively. There was no difference in treatment outcome between surgical and conservative management of symptomatic PP. Conclusion: Although this study was done in limited environment, symptomatic PP was detected at two months' postoperative period in about 1% of cases. Interlaminar approach seems to be more related with PP compared with transforaminal approach.

Effusions arising from acute pancreatitis are usually small, left sided and self limiting. The incidence of pleural effusions in acute pancreatitis is reported between 3% and 17%. In chronic pancreatitis, as a consequence of fistula and pancreatitic pseudocyst formation or by spontaneous rupture of a pancreatic psudocyst directly into thoracic cavity, extremely large effusions may be seen. When the underlying pacreatic disease is asymptomatic, the diagnosis is made by measuring the amylase content of the pleural fluid. We experience a case of left sided pleural effusions caused by pancreatico-pleural fistula associated with pancreatic pseudocyst. The diagnosis was made by measuring of pleural fluid amylase level(80000U/L). Abdominal CT scan revealed pancreatic pseudocyct and pancreatitis with extension to left pleural space through esophageal hiatus and extension to left subdiaphragmatic space. Left pleural effusions were decreased after fasting, total parenteral nutrition and percutaneous pleural fluid catheter drainage. We reported a case of pleural effusions and pacreatico-pleural fistula asssociated with asymptomatic pancreatic disease with review of literatures.

A traumatic pulmonary pseudocyst is a rare complication of blunt thoracic trauma. The clinical symptoms and signs are similar to other respiratory diseases, such as pulmonary tuberculosis. Therefore, a trauma history with the resulting radiologic and clinical findings is important for making a diagnosis. A 26-year-old male was admitted to our hospital due to cough for 3 days. The chest x-ray revealed diffuse infiltrations and a cavitary lesion at the left lung. His left chest had hit a tree as a result of motorcycle accident one day before admission. Initially, it was assumed that his symptoms and chest X-ray might be due to a tuberculosis infection. However, bronchoscopy revealed old blood clots at both lungs, particularly in the left lower lobe bronchus. A transbronchial lung biopsy showed alveolar hemorrhage. A traumatic pulmonary pseudocyst was diagnosed from his trauma history and these findings. Computed tomography of the chest performed 4 months later showed regression of the cavitary lesion.

Background/Aims: The pancreatic pseudocyst (PP) is a type of fluid collection that typically develops as a delayed complication of acute pancreatitis. Drainage is indicated for symptomatic patients and/or associated complications, such as infection and bleeding. Drainage modalities include percutaneous, endoscopic, laparoscopic, and open drainage. This study aimed to assess trends in the utilization of different drainage modalities for treating PP from 2016 to 2020. The trends in mortality, mean length of hospital stay, and mean hospitalization costs were also assessed. Methods: The National Inpatient Sample database was used to obtain data. The variables were generated using International Classification of Diseases-10 diagnostic and procedural codes. Results: Endoscopic drainage was the most commonly used drainage modality in 2018-2020, with an increasing trend over time (385 procedures in 2018 to 515 in 2020; p=0.003). This is associated with a decrease in the use of other drainage modalities. A decrease in the hospitalization cost for PP requiring drainage was also noted (29,318 United States dollar [USD] in 2016 to 18,087 USD in 2020, p<0.001). Conclusions: Endoscopic drainage is becoming the most commonly used modality for the treatment of PP in hospitals located in the US. This new trend is associated with decreasing hospitalization costs.

A pancreatic pseudocyst is the most common cystic lesion in the pancreas. There are several treatment methods with variable results. Recently, conservative treatment has been preferred because it has fewer complications. In this case, a 37-year-old male patient had pancreatic pseudocysts with upper abdominal pain, left upper back pain, diarrhea, weight loss, and general weakness. We prescribed him Banchongsangamibang (蟠蔥散加味方). For about 1 year, he was treated with oriental medicine. All of his pancreatic pseudocysts disappeared on abdominal CT follow-up and the symptoms mostly subsided. There had been no recurrence of pancreatic pseudocysts on abdominal CT follow-up after 1 year.

This report details a case of post-traumatic pseudocyst in the spleen that was successfully treated with sclerotherapy using ethanol. A sixteen-year-old boy visited our hospital for a follow-up examination of a splenic cyst. He had experienced blunt trauma to the abdomen three years prior to presentation. An abdominal computed tomography scan revealed a large cyst of the lower pole of the spleen. The cyst was $6.8{\times}9.5{\times}7.0cm$ and conservative management was tried. A follow-up ultrasonographic examination three years later revealed that the size of the cyst was unchanged and another treatment was needed to prevent complications. One session of sclerosis with ethanol (90 mL of 99% ethanol) percutaneously was applied to the cyst. A follow-up after four months revealed that the cyst had completely resolved.

An in uipo culturing to examine the cyst stage of ToxopLQsma gondii (ME49 strain) was Investigated using murine peritoneal macrophages, and we also examined the effect of CAMP or DHFR Inhibitors on the growth of bradyzoltes. For experiments ICR mice were Injected 1.p. with 1,500 brain cysts. At 1, 3, 5 and 7 days, peritoneal exudates were Isolated and then adherent peritoneal macrophages were cultured for 1,3,5 and 10 days. Growth pattern of bradyzoltes was measured by (3H)-uracil uptake assay and morphological pattern of pseudocysts formed in macrophages was observed Uth Glemsa stain. Mostly bradyzoites were observed In the macrophages extracted at 3 and S days post Infection. After 3 days in vitro, a number of pseudocysts were formed in the macrophages and the size of pseudocysts was increased during further 5 and 10 days in vitro culture. CAMP stimulated the growth of bradyzoltes when in uiuo 3 and 5 days and then in vitro 5 and 10 days conditions were applied. In case of.DHFR Inhibitors, pynmethamlne produced a linearly decremental effect with a cont.-dependent mode but methotrexate was not effective against Intracellular bradyzoltes or pseudocysts In this system. It was suggested that cyst-forming strain of T gondii (ME49 strain) could be maintained and cultivated in uitro by use of murine peritoneal macrophages. In uivo 3 and 5 days and then in uiko 5 and 10 days conditions appeared to be suitable for culturing of bradyzoltes. CAMP and pyrimethamine had an effect of stimulation and inhibition on the growth of bradyzolte, respectively.
