INTRODUCTION: Cysts of the liver round ligament are rare and they are benign in the majority of cases. Current literature has been reviewed on this subject. PRESENTATION OF CASE: A 22-year-old woman with a history of epigastric pain was admitted at our institution. Computed tomography (CT) of the abdomen showed a 14-mm cystic lesion in the epigastrium. A large cyst of the liver round ligament was successfully removed during exploratory laparoscopy and histopathology revealed a benign mesothelial cyst...

It is often assumed that implicit learning of skills based on predictive relationships proceeds independently of awareness. To test this idea, four groups of subjects played a game in which a fast-moving "demon" made a brief appearance at the bottom of the computer screen, then disappeared behind a V-shaped occluder, and finally re-appeared briefly on either the upper-left or upper-right quadrant of the screen. Points were scored by clicking on the demon during the final reappearance phase. Demons differed in several visible characteristics including color, horn height and eye size...

Little information is available on the length of the normal large intestine and its component parts in children. This information would be useful for procedures such as colonoscopy. The aim of this study was to investigate the length of the large intestine and its component parts in New Zealand children. Archival de-identified pediatric supine abdominopelvic computed tomography (CT) scans were retrospectively analyzed. After exclusion criteria, a total of 112 scans (57 males and 55 females) were included in the study and divided into three age groups: 0-2 years (n=33), 4-6 years (n=40), and 9-11 years of age (n=39)...

PURPOSE: To quantitatively investigate the characteristics of eyes with pituitary adenoma presented by three-dimensional (3D) spectral-domain optical coherence tomography (SD-OCT) using three common indices, including thickness, optical intensity ratio, and optical intensity attenuation coefficient (OIAC). METHODS: The SD-OCT database of 38 patients with pituitary adenoma and 39 normal controls were included in the study. Quadrantal and average measurements of thickness, optical intensity ratio, and OIAC were calculated for macular retinal nerve fiber layer (mRNFL), ganglion cell layer (GCL) combined with inner plexiform layer (IPL) (GCIPL) and/or the collective ganglion cell complex (GCC)...

Recently, several cases of hepatic glycogenosis (HG) have been reported. García-Suárez et al. described a young female patient with poorly controlled type 1 diabetes, right upper quadrant pain and elevated serum transaminases and GGT. After other causes of liver disease were excluded and a liver biopsy was performed, the patient was diagnosed with HG. HG is rare and can be misdiagnosed as steatohepatitis. To date, less than 20 cases have been reported in adults.

BACKGROUND: Anatomical imaging findings indicating normal bowel rotation can be identified on cross-sectional imaging, including magnetic resonance imaging (MRI) performed for non-related indications. OBJECTIVE: The goal of our study was to assess whether non-targeted MRI can accurately assess intestinal malrotation. MATERIALS AND METHODS: Four anatomical landmarks were assessed on MRIs of the chest, spine or abdomen performed from January 2006 to June 2014, on patients who also had upper gastrointestinal series (UGI) performed within 10 years of the MRI date: 1) retroperitoneal duodenum, 2) left upper quadrant duodenojejunal junction, 3) superior mesenteric artery to the left of the superior mesenteric vein, and 4) right lower quadrant cecum...

Tuberculosis (TC) is very common and significant cause of morbidity and mortality worldwide. Isolated cystic duct lymph node TC cases without involvement of gallbladder are exceedingly rare. It is difficult to diagnose preoperatively because of lack of characteristic signs and symptoms of TC. We report a man aged 45 years who presented with right upper abdominal pain since 1week. It was associated with nausea and postprandial fullness. There was no evidence of jaundice and lymphadenopathy. Abdominal examination showed moderate right upper quadrant tenderness with positive Murphy's sign and splenomegaly but no signs of peritonism...

Seeding of a central nervous system malignancy to the abdominal cavity is an uncommon but well documented complication of a ventriculoperitoneal (VP) shunt. However, the metastasis of a primary gastrointestinal cancer to the skin via a VP shunt is extremely rare. We report the clinical case of an 85-year-old male who presented with a right upper quadrant nodule over his shunt, which on histopathology and tumour marker profile was diagnosed as an adenocarcinoma of likely upper gastrointestinal origin. This case illustrates the importance of proceeding to biopsy to inform prognosis and management, despite the risks of shunt infection...

BACKGROUND: Left-sided gallbladder without situs viscerum inversus (LSG-woSVI) is a rare congenital anomaly. Clinical features and routine presurgical imaging could miss the anomalous position, thereby producing complications during surgery. Laparoscopic cholecystectomy can be performed safely, but the risk of bile duct injury (BDI) is greater than in cholecystectomy of the orthotopic gallbladder. We present a retrospective review of all scientific literature for diagnosed cases of LSG-woSVI undergoing cholecystectomy from 1996 to 2014...

IgG4-related sclerosing disease of the breast is a rare entity with 10 reports in the literature. We report the first case in a male patient. A 48-year-old male presented with 4-week history of palpable right upper outer quadrant breast mass associated with skin puckering. He reported a family history of breast cancer in his aunt. Ultrasound and mammography showed a spiculated 2.5-cm mass associated with skin retraction with extension to the pectoralis muscle. Ultrasound-guided core biopsy was performed. The findings were interpreted as acute and chronic inflammatory process...

BACKGROUND: Metastases represent a small percentage of the malignancies affecting the breast, and only 5% of melanomas originate from non-cutaneous sites. Multiple genetic aberrations have been associated with the development of melanocytic lesions, including BRAF V600E mutation. Mutations in PTEN gene have also been related to the pathogenesis of multiple malignancies. PURPOSE/METHOD: This is the case of a 28-year-old female who presented with a tender, palpable mass in the upper outer quadrant of the right breast...

Fungal inflammatory pseudotumor (FIPT) of the liver is a rare disease that may be mistaken for a malignant tumor. It is difficult to diagnose because of its nonspecific clinical and imaging features. We report the case of a 46-year-old Asian man who presented with a mass in the right upper quadrant of the abdomen. The patient had undergone transcatheter arterial chemoembolization therapy at another institution 6 months earlier, but the mass had continued to enlarge. He had no history of chronic hepatitis B, and the serum α-fetoprotein was negative...

Meibomian gland dysfunction (MGD) is a major cause of dry eye, and the purpose of the present study was to evaluate the differences between dry eye patients with MGD and controls using a novel noninvasive ocular surface analyzer. A total of 33 dry eye patients with MGD and 31 controls were enrolled in the present study. Testing included administration of the Ocular Surface Disease Index (OSDI), followed by Keratogragh 5M (Oculus, Wetzlar, Germany), measurements of the noninvasive tear film break-up times (NITBUTs), the first tear film break-up point and the morphology of meibomian gland...

Acute right upper quadrant (RUQ) pain is a common presenting symptom in emergency departments and outpatient medical practices, and is most commonly attributable to biliary and hepatic pathology. Ultrasound should be used as a first-line imaging modality for the diagnosis of gallstones and cholecystitis, as it allows the differentiation of medical and surgical causes of upper abdominal pathology, and in many circumstances is sufficient to guide patient management. Knowledge of strengths and limitations of ultrasound in the evaluation of RUQ is paramount in correct diagnosis...

BACKGROUND: Ventriculoperitoneal (VP) shunt placement is one of the most commonly performed procedures in neurosurgery. One rare complication is the formation of an abdominal pseudocyst, which can cause shunt malfunction. CASE DESCRIPTIONS: We present four unique cases of abdominal pseudocyst formation. Our first patient initially presented with a right upper quadrant pseudocyst. Shunt was externalized and the distal end was revised with placement of catheter on the opposite side...

Triple synchronous primary malignant neoplasms are rare. The exact aetiology is unknown; however, risk factors include older age, family history, genetic aberrations, prolonged exposure to carcinogens and smoking. We describe a previously healthy 48-year-old woman who presented with abdominal pain and a palpable abdominal mass. Imaging revealed a complex cystic, solid pelvic mass and another mass in the right upper quadrant. She received an extensive abdominal surgery including exploratory laparotomy, pelvic mass resection, total abdominal hysterectomy, bilateral salpingo-oophorectomy, bilateral pelvic lymphadenectomy, omentectomy and right adrenalectomy...

Isolated gallbladder agenesis is a very rare and unrecognized congenital anomaly. Patients are usually asymptomatic, but 23% present with symptoms suggestive of biliary colic. Ultrasound investigation often fails to diagnose this malformation, misinterpreted as scleroatrophic gallbladder, leading to unnecessary and potentially dangerous surgery. We report on a case of a 9-year-old child who complained of biliary colic. Ultrasound showed a possible scleroatrophic gallbladder. This diagnosis was in doubt, however, because the patient had no previous history of cholecystitis...
