Disconnected pancreatic duct syndrome (DPDS) is a rare complication of a common disease. Typically, DPDS occurs in acute necrotizing pancreatitis (ANP), chronic pancreatitis, abdominal surgery, or trauma. We present a case of DPDS from acute non-necrotizing pancreatitis (ANNP). A 41-year-old male with a history of alcohol use and prior AP presented with progressive, severe left-sided abdominal pain that was worse with movement. Labs revealed a lipase of 95 U/L (normal range 11-82 U/L). Computed tomography (CT) of the abdomen/pelvis (A/P) with IV contrast demonstrated a large left-sided pleural effusion, non-necrotic pancreatic pseudocysts, and a large subdiaphragmatic fluid collection. Thoracentesis of the pleural effusion revealed an amylase of 601 U/L confirming pancreatic etiology. A subsequent magnetic resonance cholangiopancreatography (MRCP) confirmed complex peripancreatic ascites, rapid subdiaphragmatic fluid accumulation, and a fistula from the pancreatic tail to retroperitoneum concerning for a rapidly dissecting pancreatic pseudocyst. He ultimately underwent endoscopic retrograde cholangiopancreatography (ERCP) with stent placement in the main pancreatic duct. His left-sided abdominal pain rapidly improved, and the patient was discharged. CT A/P one week after discharge showed a reduced size of subdiaphragmatic fluid collection. DPDS is usually seen in patients with a history of ANP. Our case demonstrates that it can also occur in ANNP, which has not previously been described in the literature. Therefore, a high index of clinical suspicion must be maintained for DPDS even in ANNP given its potential for severe complications.

Another name for the Puestow surgery is a lateral pancreaticojejunostomy. The primary pancreatic duct, which runs from the head to the tail of the organ, is opened, exposing the pancreas. In order to allow the pancreas to empty straight into the intestines, the opening of the pancreatic duct is subsequently joined to a tiny intestinal loop. For more than 50 years, this process has been used to effectively relieve pain caused by chronic pancreatitis. This technique has a very low mortality rate and a low rate of surgical complications, and a high success rate. The gradual fibrosis of the pancreas resulting in the loss of exocrine and endocrine function is known as chronic pancreatitis. Intense pain is the disease's most typical symptom. It is unclear what causes the discomfort in chronic pancreatitis. Nonetheless, a large number of these patients have dilated ducts that are made up of intervening structures and saccular dilations, a condition known as the "chain of lakes" phenomenon. Radiological investigations can be used for diagnosis in these patients. Lateral pancreaticojejunostomy is the most effective treatment option for these individuals. Preservation of endocrine and exocrine pancreatic function is another benefit of lateral pancreaticojejunostomy. With lateral pancreaticojejunostomy, chronic fibrocalcific pancreatitis that manifests as pancreatic ductal dilatation and persistent discomfort can be effectively treated. Excellent early outcomes have been observed in terms of pain alleviation as well as post-operative morbidity and mortality; however, the patient's overall outcome and long-term follow-up have not been as well defined.

Ophthalmology. Retina Jun 2024To differentiate intraretinal fluid (IRF) cysts from degenerative pseudocysts in neovascular age-related macular degeneration by quantitative multimodal imaging.
OBJECTIVE
To differentiate intraretinal fluid (IRF) cysts from degenerative pseudocysts in neovascular age-related macular degeneration by quantitative multimodal imaging.
DESIGN
Observational, cross-sectional.
PARTICIPANTS
Patients affected by macular neovascularization (MNV) secondary to AMD.
METHODS
All patients were analyzed by optical coherence tomography (OCT), optical coherence tomography angiography (OCTA) and dense ART (DART) OCTA. Newly onset cysts were considered IRF, whereas those cysts that were found to be persistent persistent for at least 3 months have been categorized as degenerative pseudocysts. Intraretinal cysts were automatically segmented to calculate cyst circularity. Peri-cyst space was quantitatively analyzed to assess the presence of perfusion signal and hyperreflective foci (HF).
MAIN OUTCOME MEASURES
Best-corrected visual acuity (BCVA), cyst circularity, peri-cyst perfusion, peri-cyst HF, fibrosis, outer retinal atrophy.
RESULTS
We analyzed 387 cysts collected from 35 eyes of 35 neovascular AMD patients (14 males; mean age 80±5 years). We classified 302 IRF cysts and 85 degenerative pseudocysts. IRF cysts were characterized by significantly higher circularity (0.86 (range 0.81-0.91), perfusion signal in the peri-cyst space and peri-cyst HF in 89% of cases (all p<0.05). Degenerative pseudocysts showed significantly lower circularity (0.68 (range 0.64-0.76), no perfusion signal in the peri-cyst space and peri-cyst HF only in 29% of cases (all p<0.05). The adopted quantitative metrics significantly correlated with disease duration, number of injections, fibrosis and outer retinal atrophy.
CONCLUSIONS
IRF can be discriminated from degenerative pseudocysts by quantitative multimodal imaging approach. These findings resulted clinically relevant and should be included in future training models for artificial intelligence algorithms to improve the diagnostic power and the fluids monitoring in neovascular AMD.

Osteoporosis is a condition with reduced bone mass and disrupted architecture. Osteoporosis affects the Temporomandibular disorders (TMD) by changing bone density and quality. This study aims to determine the nature and extent of temporomandibular joint (TMJ) involvement in osteoporotic patients by correlating TMJ morphological changes detected by CBCT with systemic bone health indicated by BMD T-scores from DEXA and analyzing BTMs in serum and saliva. This study was a cross-sectional study conducted from May 2021 to December 2022. It involved 50 participants divided into two groups (N=25). One group was healthy male, while the other group had osteoporosis male. Saliva and blood samples were collected, and diagnostic imaging was conducted. The prevalence of various bone changes in the condyle was examined using CBCT. Erosion was found to be the most common, followed by Flattening, Osteophyte, and Subchondral cysts. The study group had significantly higher rates of smooth condyle, erosive lesions, and osteophytes compared to the control group. Pseudocyst decreased on the right side but increased on the left side. Pain on the right side increased more in the study group, and the T score for osteoporosis was higher in the study group. Joint spaces, condyle diameter, and glenoid cavity measurements differed significantly between sick and healthy people, as shown by CBCT (P≤0.001). Only the ALP parameter in the serum showed a significant increase in the study group compared to the control group. Saliva analysis revealed higher levels of calcium, osteocalcin, and ALP in the case group compared to the control group. The results of this study showed that CBCT as a specialized technique in imaging by providing detailed images can be used to evaluate osteoporosis and be used as an accurate diagnostic tool.

Pancreatic pseudocysts are surrounded by a non-epithelialized wall confined to the pancreas and localized to the pancreatic tissue or adjacent pancreatic cavity. In contrast, pancreatic cystic tumors occur less frequently than solid lesions and are often detected incidentally on imaging. Regarding the qualitative diagnosis of pancreatic pseudocysts, it is important to differentiate them from neoplastic cysts. We report the case of a 74-year-old woman with a giant hemorrhagic pancreatic pseudocyst and a suspected cystic pancreatic tumor, wherein distal pancreatectomy and splenectomy with lymph node dissection were performed. The patient was discharged 11 days postsurgery, with a good postoperative course. There are no reports of giant pancreatic pseudocysts larger than 10 cm with hematoma contents. The presumptive diagnosis of pseudocysts based on imaging alone may be difficult. Surgical resection is considered when it is difficult to distinguish a giant pancreatic pseudocyst from a cystic neoplasm.

Pancreatitis, panniculitis, and polyarthritis (PPP) syndrome presents a unique challenge in diagnosis and management because of its rarity and heterogeneous initial presentation. This manuscript presents a case series of two patients with PPP syndrome, shedding light on the diagnostic process and care for this uncommon condition. PPP syndrome is characterized by the simultaneous occurrence of pancreatitis or pseudocysts alongside polyarthritis and panniculitis. While its exact pathophysiology remains obscure, pancreatic inflammation is assumed to trigger the hematogenous dissemination of pancreatic enzymes, leading to fat necrosis and subsequent panniculitis, as well as chondronecrosis and/or osteonecrosis causing polyarthritis. Despite its recognition in medical literature since the late 1980s, PPP syndrome remains poorly understood, with only a limited number of cases reported globally. Its rarity and varied initial manifestations often result in misdiagnosis, causing delays in appropriate treatment. The presented case series highlights key clinical features and diagnostic clues of PPP syndrome. Both patients exhibited initial symptoms of inflammatory polyarthritis, accompanied by characteristic findings of "ghost cells" on skin biopsy. Additionally, radiographic and laboratory evidence revealed pancreatic changes consistent with this syndrome. This case series underscores the importance of multidisciplinary collaboration in managing PPP syndrome. Early recognition and accurate diagnosis are pivotal in initiating prompt and effective therapeutic interventions, thereby improving patient outcomes and minimizing long-term sequelae.

Hepatic artery pseudoaneurysm (HAP) is an uncommon yet critical complication of acute pancreatitis. This case delves into the unusual scenario of a two-month-old male infant with a familial history of pancreatitis who develops the condition himself. Despite initial treatment, the infant's symptoms worsened, unveiling a pancreatic pseudocyst (PCC) and an atypical pseudoaneurysm stemming from the hepatic artery, a rare complication in acute pancreatitis. The pseudoaneurysm's confirmation through selective angiography and its subsequent management using embolization is highlighted. This report emphasizes the rarity of hepatic artery pseudoaneurysm in the context of acute pancreatitis, stressing the need for thorough imaging to spot arterial involvement. Early identification via selective angiography remains crucial due to the high risks associated with pseudoaneurysm rupture, underscoring the urgency for prompt intervention. In summary, this case spotlights the infrequent occurrence of hepatic artery pseudoaneurysm secondary to acute pancreatitis in an infant. It stresses the importance of swift recognition and intervention to avert potentially life-threatening complications.

The article by Ker explores the treatment of peripancreatic fluid collection (PFC). The use of percutaneous drainage, endoscopy, and surgery for managing PFC are discussed. Percutaneous drainage is noted for its low risk profile, while endoscopic cystogastrostomy is more effective due to the wider orifice of the metallic stent. Surgical cystogastrostomy is a definitive treatment with a reduced need for reintervention, especially for cases with extensive collections and significant necrosis. The choice of treatment modality should be tailored to individual patient characteristics and disease factors, considering the expertise available.

European Radiology May 2024To investigate the imaging features of pancreatic ductal adenocarcinoma (PDAC) with histological large duct pattern.
OBJECTIVES
To investigate the imaging features of pancreatic ductal adenocarcinoma (PDAC) with histological large duct pattern.
METHODS
Our study included 37 patients (mean age, 66.5 years; 22 women) with surgically proven PDAC with histological large duct pattern, whose imaging features were classified into four types: Type I, solid mass; Type II, predominantly cystic mass with intracystic solid components; Type III, predominantly solid mass with intratumoral cysts; and Type IV, solid mass with peritumoral retention cysts or pseudocysts. Two radiologists independently analyzed both CT and MRI images for the morphological type, presence of abrupt main pancreatic duct (MPD) cutoff, adjacent vascular invasion, diffusion restriction, and reached consensus.
RESULTS
On CT, 26 patients (70.3%) had Type I tumors, five (13.5%) had Type II, three (8.1%) had Type III, and three (8.1%) had Type IV. Among the 26 patients with Type I tumors on CT, 16 had tumors with multiple intratumoral cysts within the solid mass on MRI and were subsequently classified as Type III. Accordingly, 10 patients (27.0%) were classified as Type I, five (13.5%) as Type II, 19 (51.7%) as Type III, and three (8.1%) as Type IV on MRI. Of the 37 patients, 27 (73.0%) had an abrupt MPD cutoff, 15 (40.5%) had adjacent vascular invasion, and 25 (67.6%) had diffusion restriction on MRI.
CONCLUSIONS
Predominantly solid pancreatic masses with small intratumoral cysts visualized on MRI may be a characteristic imaging finding of PDAC with histological large duct pattern, and differentiate it from conventional PDAC or other cystic pancreatic tumors.
CLINICAL RELEVANCE STATEMENT
Radiologists should be familiar with the various imaging features of PDAC with histological large duct pattern and should be aware that it may mimic other solid or cystic tumors of the pancreas.
KEY POINTS
Imaging features of pancreatic ductal adenocarcinoma with histological large duct pattern can be classified into four types. This pathology more frequently appears as a predominantly solid mass with intratumoral cysts on MRI than on CT. Adding MRI to CT may help identify pancreatic ductal adenocarcinoma with histological large duct pattern.
