BACKGROUND: Bronchopulmonary sequestration is a congenital abnormality of the primitive foregut. In adults, the typical age at presentation is 20-25 years. CASE REPORT: A 64-year-old female was referred for evaluation of an 8 × 6-cm right lower lobe cystic lesion. Her medical history was significant for recurrent right lower lobe pneumonia requiring multiple hospitalizations. Her physical examination was significant for crackles at the right lung base. Computed tomography (CT) of the chest with contrast showed cystic changes with thickened septation of the medial segment of the right lower lobe lacking distinct visceral pleura and with arterial supply from the anomalous branch of the thoracic aorta arising near the celiac trunk...

Literature on the behavior of cystic lesions in pancreas transplants is scarce, and hence a better understanding is warranted. Data on recipients and their respective donors that underwent simultaneous kidney and pancreas, pancreas transplant alone, and pancreas after kidney between 1994-2015 were reviewed (n=1185). Cystic lesions of the transplant pancreas developed in 22 patients (1.8%): 12 pseudocysts, 2 cysts/remnants, 4 intraductal papillary mucinous neoplasms (IPMN), 2 adenocarcinomas, 1 low grade intraepithelial pancreatic neoplasia, and 1 case of polycystic kidney disease...

BACKGROUND: In patients with polycystic liver disease, development of cysts induces hepatic venous outflow obstruction (HVOO) and parenchymal modifications, challenging the paradigm of a normal non-cystic liver parenchyma. The aims were to reappraise the pathology of the non-cystic parenchyma, by focusing on HVOO lesions; and to investigate the association with outflow obstruction at imaging and perioperative course after liver resection. METHODS: This is a retrospective study conducted in one tertiary center between 1993 and 2014...

In this review, we will focus on rare pancreatic tumors. Most of these tumors do not have distinct characteristic appearances so the key to diagnosis requires a combination of imaging appearance, laboratory data, patient demographics, and associated medical syndromes in order to narrow the differential diagnosis. Nonetheless, imaging plays a vital role in narrowing the differential and guiding management. While there are many variant pathologic entities that cannot be encompassed by a single review, we aim to illustrate the imaging appearance of less common pancreatic tumors highlighting key distinctive diagnostic characteristics and discuss the implications for management...

Aims: Loss-of-function mutations in the hERG gene causes long-QT syndrome type 2 (LQT2), a condition associated with reduced IKr current. Four different mutation classes define the molecular mechanisms impairing hERG. Among them, Class 2 mutations determine hERG trafficking defects. Lumacaftor (LUM) is a drug acting on channel trafficking already successfully tested for cystic fibrosis and its safety profile is well known. We hypothesize that LUM might rescue also hERG trafficking defects in LQT2 and exert anti-arrhythmic effects...

The accurate diagnosis of ovarian torsion is imperative, as loss of the ovary can have long-term consequences in terms of fertility. However, a nonspecific clinical presentation in conjunction with a highly variable imaging appearance makes the diagnosis of ovarian torsion challenging. This is complicated even further in the pediatric population, as these patients cannot always articulate their symptoms or provide an adequate medical history. Therefore, imaging has a critical role in the diagnosis of ovarian torsion in pediatric patients...

The literature is highly conflicting on hepatobiliary mucinous cystic neoplasms (MCNs), aka "hepatobiliary cystadenoma/cystadenocarcinoma," largely because ovarian stroma (OS) was not a requirement until WHO-2010 and is not widely applied even today. In this study, MCNs (with OS) accounted for 24 of 229 (11%) resected hepatic cysts in one institution. Eight of the 32 (25%) cysts that had been originally designated as hepatobiliary cystadenoma/cystadenocarcinoma at the time of diagnosis proved not to have an OS during this review and were thus re-classified as non-MCN...

The four C. elegans excretory canals are narrow tubes extended through the length of the animal from a single cell, with almost equally far extended intracellular endotubes that build and stabilize the lumen with a membrane and submembraneous cytoskeleton of apical character. The excretory cell expands its length approximately 2,000 times to generate these canals, making this model unique for the in vivo assessment of de novo polarized membrane biogenesis, intracellular lumen morphogenesis and unicellular tubulogenesis...

Neuroendoscopical images of fluid-filled cavity walls within encephalic tumours in thirteen adult patients were correlated with histopathology results of samples harvested during surgery. Extensive vascular proliferation, with mesh-like formations in a 3D pattern, as well as onionskin appearance, were observed in malignant tumours, as opposed to normal or slightly increased vascular pattern, observed in benign neoplasms. Medical facilities lacking sufficient technical resources where limited pathologist experience is expected, and can be associated with intraoperative histological misdiagnosis...

Renal cell carcinoma (RCC) exhibits a diverse and heterogeneous disease spectrum, but insight into its molecular biology has provided an improved understanding of potential risk factors, oncologic behavior, and imaging features. Computed tomography (CT) and MR imaging may allow the identification and preoperative subtyping of RCC and assessment of a response to various therapies. Active surveillance is a viable management option in some patients and has provided further insight into the natural history of RCC, including the favorable prognosis of cystic neoplasms...

Hydatid disease is a parasitic infection whose etiologic agent is Echinococcus granulosus. Human is an accidental intermediate host and the most common site is the liver. The brain involvement is unusual and up to 75% of cases are described in the pediatric population. We present six children with cerebral hydatid disease admitted to the Pediatric Hospital J.P. Garrahan. All had neurological involvement on admission. The images showed single cystic lesion in the brain. They did not present involvement in other organs...

Pleuropulmonary blastoma (PPB) is a rare malignancy of childhood which when left untreated often shows pathologic progression resulting in a more aggressive neoplasm with an increasingly poor prognosis. Because of this it is important to diagnose and initiate treatment early. However, early stage PPB can appear as a cystic lung lesion on imaging and can be easily misdiagnosed given the rarity of the malignancy. Moreover, current therapeutic guidelines for these lesions are not well established, making treatment decisions and management difficult for clinicians...

Peliosis Hepatis (PH) is a rare vascular disorder of the liver, characterized by the presence of cystic blood-filled cavities distributed throughout the hepatic parenchyma. The pathogenesis of PH remains controversial. The preoperative diagnosis of PH is difficult, due to the non-specific imaging characteristics of PH and almost all cases are diagnosed on histology post resection. This study presents a case of PH masquerading as hepatocellular carcinoma (HCC). The patient is a 45-year old Chinese lady, who presented with transaminitis...

BACKGROUND: Vascular anomalies are a heterogeneous group of disorders seen in children and adults. A standard nomenclature for classification has been offered by the International Society for the Study of Vascular Anomalies. Its application is important for communication among the multiple specialties involved in the care of patients and for planning treatment, as well as for research and billing. We hypothesized that terminology still is not uniformly applied, and that this could have an impact on treatment...

The patient was a 39-year-old woman in whom computed tomography (CT) in 201X had revealed a pancreatic cystic neoplasm (PCN) of 4.3 cm in diameter in the pancreatic body. In June 201X + 3, the patient consulted our hospital regarding severe acute pancreatitis. The condition improved through treatment with large-volume fluid replacement and continuous regional arterial infusion therapy. Thereafter, acute pancreatitis recurred twice, in November 201X + 3 and in January 201X + 4. During an 8-month period, acute pancreatitis occurred three times...

BACKGROUND AND AIM: Cholangitis, bacteremia and pyogenic liver abscess (PLA) can be often caused by intrahepatic bile ducts stone (IBDS), which is endemic to Southeast Asia. The association between IBDS and cholangiocarcinoma has been well recognized. Concomitant cholangiocarcinoma in the PLA related to IBDS is often missed. METHODS: A case-control study consisting of 64 patients with PLA related to IBDS and 256 control patients with PLA not related to IBDS was used to investigate clinical features of PLA and incidence of concomitant cholangiocarcinoma in patients with PLA related to IBDS...
