INTRODUCTION
Visceral pseudoaneurysms are prone to rupture and can cause mass effect on surrounding structures, with extrinsic compression on the biliary tree being a rare but challenging complication.
CASE PRESENTATION
We report a case of a 48-year-old man with a history of alcohol excess who presented acutely unwell with jaundice. Imaging revealed a pseudoaneurysm of the accessory right hepatic artery extending into an adjacent pancreatic pseudocyst, leading to common bile duct compression. Successful management included pseudoaneurysm exclusion with a stent graft and concurrent alleviation of the biliary obstruction.
CONCLUSION
Managing pancreatic pseudocysts with biliary compression becomes complicated when an accompanying pseudoaneurysm is present, elevating the associated risk. In this case, stent graft exclusion of the pseudoaneurysm was the chosen approach to preserve arterial flow with potential for long-term patency. Delayed pseudoaneurysm diagnosis underscores the importance of comprehensive assessment in complex presentations, such as jaundiced alcoholic patients, where the possibility of pancreatitis episodes necessitates evaluation of the visceral vasculature for pseudoaneurysms.

Pancreatic sinistral portal hypertension (PSPH) is a common complication of acute pancreatitis (AP) and can cause massive gastrointestinal bleeding, which is one of the causes of AP-related mortality. However, there is currently no predictive model for AP concurrent with PSPH. This study aimed to identify the risk factors for AP concurrent with PSPH and use these factors to build a related predictive model. We collected clinical data from 282 patients with AP. 192 patients were used as a training group and 90 patients as a validation group. Univariate and multivariate analyses were used to identify independent risk factors for AP complicated with PSPH, and then a nomogram was established. The models are cross verification and Internal verification. The predictive ability and accuracy of the model were evaluated based on the working curve of the subjects and the calibration curve, respectively. The clinical value of the model was evaluated using decision curve analysis (DCA). The univariate analysis revealed significant differences in the occurrence of PSPH with respect to sex, recurrent AP, history of hypertension, smoking history, patency of the splenic vein, pancreatic necrosis or pancreatic pseudocyst formation, the most significant site of pancreatic swelling, presence of a Dmure D polymer, MCTSI, and involvement of lipase and amylase. The logistic multivariate regression analysis showed that male sex, splenic-vein stenosis or occlusion and swelling were located in the body-tail, and MCTSI was an independent risk factor for PSPH. The nomogram and ROC curve were constructed. The area under the working curve of the subjects was 0.91, and the sensitivity and specificity were 82.5% and 89.1%, respectively. In the validation group, the C-index is 0.826. The nomogram was internally validated using 1,000 bootstrap samples, and the c-index was 0.898. The calibration curve demonstrated that the predicted probability was concordant with the observed probability, and the DCA confirmed that the model had robust clinical utility. Male sex, splenic-vein stenosis or occlusion, recurrent AP, and swelling are located in the body-tail, and MCTSI is an independent risk factor for the occurrence of PSPH. The predictive model developed for AP complicated with PSPH may serve toward developing preventive and therapeutic approaches for PSPH.

BACKGROUND
Ligamentum flavum cysts, which are most common in mobile junctional levels of the spine, can be a rare cause of spinal stenosis. There have been several case reports of ligamentum flavum cysts. However, there is yet to be a documented case report of a calcified ligamentum flavum cyst. Herein, we report the first case of a calcified ligamentum flavum cyst causing ankle and toe weakness.
CASE SUMMARY
A 66-year-old male visited our hospital complaining of claudication as well as thigh and calf pain in his left leg, all beginning two weeks prior. Physical examination revealed motor weakness of the left ankle dorsiflexion and great toe dorsiflexion. Lumbar spinal computed tomography scans showed spinal stenosis combined with a calcified mass at the left side of the L4-5 level. Magnetic resonance imaging showed dural sac compression caused by the calcified mass at the left ligamentum flavum of the L4-5 level. We performed decompressive laminectomy and excision of the calcified mass combined with posterior lumbar interbody fusion at the L4-5 level. Intra-operatively, we found a firm and nodule like mass originating from the ventral surface of ligamentum flavum. Pathological examination suggested a calcified pseudocyst without a capsular lining. After the operation, the patient's motor weakness in the ankle and great toe improved gradually.
CONCLUSION
The patient's ankle and great toe weakness were improved successfully after surgical removal of the calcified cyst.

BACKGROUND
Mesenteric cysts are one of the rarest abdominal tumor masses, representing a little-studied pathology. In turn, the variability and non-specificity of clinical manifestations make diagnosis difficult, as it can be reached by imaging findings due to another cause or by non-specific abdominal pain.
CASE PRESENTATION
This article describes the case report of an asymptomatic 28-year-old patient who presented a 6-cm abdominal cystic mass with mixed density, which was found incidentally by computed tomography. Exploratory laparoscopy was performed followed by conversion to conventional surgery to extract the tumor mass. The anatomical pathology diagnosis was pseudocyst of the mesentery root. Mesenteric cysts are one of the rarest abdominal tumor masses, representing a little-studied pathology. In turn, the variability and non-specificity of clinical manifestations make diagnosis difficult, as it can be reached by imaging findings due to another cause or by non-specific abdominal pain.
CONCLUSIONS
Mesenteric cysts are rare, and their nonspecific symptoms often lead to diagnosis based on imaging findings. Complete laparoscopic enucleation is the standard treatment.

One frequent side effect of chronic pancreatitis is pancreatic pseudocyst. Abdominal pain and vomiting are common complaints that the patient presents with. However, atypical manifestations of pancreatic pseudocyst still confound medical professionals worldwide, making identification challenging and ultimately increasing the risk of fatal consequences. We describe the case of a 41-year-old man who had decompensated liver cirrhosis linked to alcohol intake. The patient presented with dysphagia and yellowish skin discolouration, which, upon further investigation, turned out to be peripancreatic pseudocysts extending into the mediastinum. Diagnostic challenges arose due to the rare occurrence of a pancreatic pseudocyst located in the mediastinum. Patient was treated with a culture-sensitive antibiotic and on follow up he was doing well.

INTRODUCTION
Visceral arterial aneurysms and pseudoaneurysms are rare but dangerous pathologies, with reported incidence of 0.01-0.2% of the worldwide population, as found on autopsy. Pancreaticoduodenal artery pathology accounts for approximately 2% of all visceral aneurysms; it is commonly caused by chronic inflammatory processes, such as pancreatitis or adjacent pseudocysts. Morbidity and mortality commonly result from rupture of the aneurysm itself, leading to life-threatening hemorrhage into the peritoneum or gastrointestinal tract.
CASE REPORT
Here we present the case of a 64-year-old male patient with previous history of alcohol use disorder leading to chronic pancreatitis and prior embolization of an inferior pancreaticoduodenal pseudoaneurysm, who presented to the emergency department (ED) with abdominal pain, nausea, and vomiting, and was found to have a large recurrent inferior pancreaticoduodenal pseudoaneurysm with associated obstructive cholangitis and pancreatitis via contrast-enhanced computed tomography (CT) of the abdomen and pelvis. The patient was managed emergently by interventional radiology angiography with embolic coiling and percutaneous biliary catheter placement, and he subsequently underwent biliary duct stenting with gastroenterology. The patient was successfully discharged after a brief hospitalization after resolution of his pancreatitis and associated hyperbilirubinemia.
CONCLUSION
Pancreaticoduodenal artery aneurysms and pseudoaneurysms are rare and dangerous visceral pathologies. Patients can be diagnosed rapidly in the ED with CT imaging and need urgent endovascular management to prevent morbidity and mortality.

Pleural effusion can be a complication of pancreatic diseases. Pancreaticopleural fistula (PPF) is a rare complication arising as a result of chronic pancreatitis that causes recurrent pleural effusions often resistant to thoracentesis. Diagnosis of PPF can be delayed, and presentation with respiratory symptoms related to pleural effusion is common. Elevated pleural fluid amylase and lipase levels are always helpful, but final diagnosis mostly requires demonstration of fistula on imaging modalities, such as computed tomography (CT) scan or magnetic resonance cholangiopancreatography (MRCP). Endoscopic retrograde cholangiopancreatography (ERCP) serves as a diagnostic and therapeutic tool. Here, we present a case of PPF leading to recurrent pleural effusions, treated with stent placement.

Review
Well-defined, faintly radiopaque lesions are occasionally observed in the antrum of the maxillary sinus in asymptomatic patients during maxillary sinus floor elevation. These lesions are treated as antral pseudocysts (AP) based on the clinical diagnosis in some cases, and maxillary sinus floor elevation is performed without enucleating these lesions. However, further surgery is required after implant placement if the lesion is a mucocele, odontogenic cyst, or tumour. This comprehensive clinical review aimed to identify an appropriate approach for maxillary sinus floor elevation in patients with well-defined, faintly radiopaque lesions in the antrum based on our clinical experience.

INTRODUCTION
Cystic lesions in the liver are commonly encountered space-occupying lesions having various etiologies such as simple cysts, malignancies, hydatid cysts, and pancreatic pseudocysts.
CASE PRESENTATION
An eight-year-old girl initially presented with acute abdominal pain, fever, and a cystic lesion in the upper abdomen. Surgical intervention was performed based on an initial diagnosis of an inflammatory cyst. Later, she developed pleural effusion. Further investigations, unveiled a cystic mass arising from the head of the pancreas, and a pancreatico-pleural fistula. Retrospective analysis revealed a history of trauma that started her illness course. Conservative management involving intercostal tube drainage and octreotide infusion resulted in a favorable outcome.
DISCUSSION
Pancreatic pseudocyst is typically results from pancreatitis or trauma but in rare cases, they can have extended to unusual locations such as the liver. This case highlights the varied presentations and complex interplay of symptoms associated with intrahepatic pseudocysts. The initial oversight of trauma in the patient's history underscore the importance of thorough history-taking for an accurate diagnosis. The complexity of this case emphasize the necessity of a multidisciplinary approach in managing such atypical presentations.
CONCLUSION
Intrahepatic pseudocysts, especially those resulting from post-traumatic pancreatic pseudocyst, are uncommon and are not typically included in the differential diagnosis of liver lesions. This case highlights the significance of identifying unusual presentation and thoroughly investigating the patient's medical history to make an accurate diagnosis. A multidisciplinary approach is essential for effective patient management in these complex cases.

INTRODUCTION
Upper gastrointestinal (GI) bleeding in patients with roux-en-Y gastric bypass can be difficult to localize. Marginal ulcers are the most common cause, but a broad differential should be maintained in cases of severe bleeding, especially since the stomach and duodenum are not easily accessible by regular upper endoscopy.
PRESENTATION OF CASE
A 38-year-old female with Roux-en-Y gastric bypass presented with abdominal pain and hematochezia. Due to history of smoking and heavy use of ibuprofen, she was initially thought to have a bleeding marginal ulceration. Further investigation with computed tomographic (CT) angiography revealed a splenic artery pseudoaneurysm that had ruptured into a pancreatic pseudocyst, the gastric remnant and the peritoneum. The patient underwent successful treatment with trans-arterial embolization.
DISCUSSION
Splenic artery pseudoanerysms are rare but potentially lethal if unrecognized, particularly in patients with altered foregut anatomy. Their most likely origin is a nearby pancreatic pseudocyst, which erodes into the splenic artery by direct pressure and enzymatic digestion. Bleeding inside the pseudocyst is the most feared complication, resulting in massive intraperitoneal, extraperitoneal or endoluminal hemorrhage. Surgery is particularly challenging due to intense peripancreatic inflammation. Trans-Anterial embolization is the preferred treatment modality.
CONCLUSION
Marginal ulcers continue to be the most common cause of GI bleeding in patients with Roux-en-Y anatomy, although high index of suspicion for alternative diagnosis should be maintained in cases of massive hemorrhage.
