Newest firstIsolated neurofibromas of the gallbladder (GB) and common bile duct (CBD) are exceptionally rare benign tumors, often mimicking malignancies and posing diagnostic challenges. This paper reports the unique case of a 32-year-old male presenting with right upper quadrant pain, jaundice, and clay-colored stools. Imaging revealed a septate GB with mural thickening, a gallstone, and distal CBD annular thickening, indica…
Open article record in new tab ↗Rationale Adenomyomatosis is a rare benign condition characterized by epithelial proliferation and diverticular formation in the gastrointestinal tract, most commonly affecting the gallbladder. Its occurrence in the bile duct is uncommon but significant, as it can cause biliary obstruction, cholestasis, and abdominal pain-symptoms that closely mimic early-stage cholangiocarcinoma. This overlap creates diagnostic c…
Open article record in new tab ↗Injuries to the common bile duct (CBD) have been reported in 0.4-0.5% of penetrating trauma cases across several series. Gunshot wounds pose unique challenges due to the thermal injury caused by the projectile, combined with the close anatomical proximity of the CBD, portal vein, and hepatic artery within the hepatoduodenal ligament. This proximity often results in combined injuries to these vital structures, whic…
Spontaneous pneumomediastinum (SPM) is a rare, self-limiting condition that can be complicated by pneumothorax, pneumopericardium, and subcutaneous emphysema. This case describes a 25-year-old man with a chronic marijuana use history who developed SPM after a recent respiratory infection. Imaging showed significant pneumomediastinum, pneumopericardium, and small pneumothoraces bilaterally. Despite these findings,…
Purpose To assess (I) whether, in autopsy-proven lethal intoxications with opiates/opioids, a dilatation of the common bile duct (CBD) is still visible in postmortem computed tomography (PMCT) and (II) if a dilatation of the CBD might also be measurable for other substance groups (e.g., stimulants, hypnotics, antipsychotics, etc.). Methods We retrospectively measured the CBD using PMCT in cases with lethal intoxic…
Hypoxia caused by ischemia induces acidosis and neuroexcitotoxicity, resulting in neuronal death in the central nervous system (CNS). Monoacylglycerol lipase (MAGL) is a modulator of 2-arachidonoylglycerol (2-AG), which is involved in retrograde inhibition of glutamate release in the endocannabinoid system. In the present study, we used positron emission tomography (PET) to monitor MAGL-positive neurons and neuroi…
Open article record in new tab ↗Background Electronic cigarettes/e-cigarettes (ECs), or vaping, is currently the most popular form of smoking amongst youth in the United States. ECs are battery-powered devices that vaporize a liquid that comes in small cartridges, or pods, that contain various chemicals, nicotine, and an array of flavors that can be modified to include cannabinoids (THC). With increasing popularity, however, there is an epidemic…
Open article record in new tab ↗At the European Society of Cardiology (ESC) congress of this year 2018, held in Munich from August 25th to 29th, 4594 abstracts were presented. Of those, 423 (10.8%) belonged to an imaging category. Experts in echocardiography (VD), cardiovascular magnetic resonance (CMR) (CBD), nuclear imaging (OG), and cardiac computed tomography (CT) (PMH) have selected the abstracts in their areas of expertise that were of mos…
Background Biliary intraepithelial neoplasia (BilIN) is often distinguished by what it is not: the precancerous lesions are not mass-forming, are not the cause of bile duct obstruction, and are small enough (less than 5 mm long) to evade detection by the naked eye. Here, we describe an atypical case of BilIN resembling cholangiocarcinoma (CC) that was large enough to be identified by diagnostic imaging and present…
A congenital bladder diverticulum (CBD) is caused by inherent muscular weakness instead of obstruction of the bladder outlet. The major clinical conditions are recurrent urinary tract infection (UTI) and voiding dysfunction. This report describes a 15-year-old male adolescent who developed sudden visual disturbance resulting from hypertensive retinopathy. The cause of hypertension was bilateral obstructive uropath…
Background Many radiological signs are known for the diagnosis of idiopathic normal pressure hydrocephalus (iNPH). However, there is little information about these signs in the pre-symptomatic phase. For pathophysiological investigative purposes we conducted a descriptive image analysis study on pre-symptomatic patients. Methods Patients that had contact with either the neurological or neurosurgical department of…
Open article record in new tab ↗Background/aims When computed tomography (CT) does not indicate choledocholithiasis in highly suspicious patients, there is no definite consensus on the subsequent modality. Endoscopic ultrasonography (EUS) indicates fewer procedure-related complications than endoscopic retrograde cholangiopancreatography (ERCP) and has a lower cost than magnetic resonance cholangiopancreatography. Therefore, we aimed to investiga…
Duplicated gallbladder (GB) is a rare congenital disease. Surgical management of a duplicated GB needs special care because of concurrent bile duct anomalies and the risk of injuring adjacent arteries during surgery. An 80-year-old man visited an emergency room with right upper quadrant abdominal pain. Computed tomography (CT) revealed cholecystitis with a 2-bodied GB. Because of this unusual finding, magnetic res…
Background Although various endoscopic techniques in situs inversus have been reported, endoscopic retrograde cholangiopancreatography (ERCP) in patients with situs inversus is always challenging even for an experienced endoscopist. We performed ERCP using two different techniques, and compare the merits of each technique. Case presentation A 74-year-old woman presented with epigastric pain and jaundice for 3 days…
Background/aim To retrospectively assess the accuracy of intravenous (IV) contrast-enhanced multidetector CT (MDCT) in choledocholithiasis detectability, in the presence and absence of positive intraduodenal contrast. Patients and methods Over a 3-year period, patients in whom endoscopic retrograde cholangiopancreatography (ERCP) was performed within a week from a portovenous (PV)-enhanced abdominal CT were identi…
Rationale Obstructive jaundice can raise problems to diagnostic imaging. The radiologist must choose the most appropriate examination that delivers the most important diagnostic information because the differences between a lithiasic obstruction and a tumoral one are vital. This information helps the surgeon speed up the process of decision-making, because the treatment may be very different in relation to the nat…
Duodenal diverticula are detected in up to 27% of patients undergoing upper gastrointestinal tract evaluation with periampullary diverticula (PAD) being the most common type. Although PAD usually do not cause symptoms, it can serve as a source of obstructive jaundice even when choledocholithiasis or tumor is not present. This duodenal diverticulum obstructive jaundice syndrome is called Lemmel's syndrome. An 81-yr…
Background Carcinoid tumors are usually considered to have a low degree of malignancy and show slow progression. One of the factors indicating the malignancy of these tumors is their size, and small ampullary carcinoid tumors have been sometimes treated by endoscopic resection. Case presentation We report a case of a 63-year-old woman with a minute ampullary carcinoid tumor that was 7 mm in diameter, but was assoc…
