BACKGROUND: Peliosis hepatis is an uncommon vascular condition characterized by multiple, randomly distributed, blood-filled, and cyst-like cavities throughout the liver. The unique clinical nature consisting of an asymptomatic, benign, and incidental finding sometimes conceals itself even until autopsy. However, the exact pathomechanism remains as yet unproven. METHOD: We encountered the patient with multiple hypervascular masses in the whole liver and investigated the clinicopathological features underlying this condition...

BACKGROUND: Computed tomographic angiography is increasingly used during surgical planning for abdominally based microvascular breast reconstruction. Cost-analysis studies have demonstrated a benefit to the use of computed tomographic angiography, although the secondary costs of incidental findings have not been previously reported. This study investigates the cost of computed tomographic angiography, taking into account the cost of incidental findings found during imaging. METHODS: Patients undergoing preoperative computed tomographic angiography in preparation for autologous abdominally based breast reconstruction from July of 2010 through May of 2014 were included in this study...

Syphilis is a rare disease in the rectum. It is difficult to diagnose because the characteristics of the rectal syphilis rectal lesion are highly varied. The endoscopic findings of rectal syphilis are proctitis, ulcers, and masses. If rectal syphilis is suspected to be the cause for rectal lesions, it is important for physicians to consider the sexual history and sexual orientation of the patient. We report a case of incidental rectal syphilis in a 41-year-old man diagnosed during a regular medical check-up...

Most esophageal lipomas are discovered incidentally and are small and asymptomatic. However, large (>4 cm) lipomas may cause various symptoms, including dysphagia, regurgitation, or epigastric discomfort. We present a 45-year-old woman with intermittent sudden choking and globus pharyngeus. Upper gastrointestinal endoscopy and endoscopic ultrasound revealed an approximately 10.0×1.5 cm pedunculated subepithelial tumor in the upper esophagus, identified as the cause of her symptoms. A thoracic computed tomography scan revealed a fat attenuated longitudinal mass along the upper esophagus, suggestive of a lipoma...

Sex differences in object location memory have been widely studied, with mixed results. The role of attention in mediating the female advantage in object location memory has not been clearly understood yet. Two experiments, involving 181 participants and using an actual object array, were conducted in the present study to examine two learning conditions: incidental and intentional. In each experiment, participants were randomly assigned to divided versus full attention conditions. The study also examined memorizing location-maintained and location-exchanged objects...

Adrenal hemangioma is an uncommon benign vascular tumor that is often discovered incidentally. It has never been reported in association with familial adenomatous polyposis. We report a case of a 60-year old man with a history of familial adenomatous polyposis, in whom a huge retroperitoneal cyst of 18x17 cm was discovered during routine radiologic evaluation. Because of the impossibility of ruling out the presence of malignancy, surgical cystectomy was performed, associated to a scheduled total colectomy. Pathological examination revealed that the cyst corresponded to an adrenal cavernous hemangioma...

Breast cancer is approximately 100 times less common among men. Estrogen-related receptor α was detected in human prostate cancer tissue, and androgen receptors are expressed in both normal and malignant breast tissue. Thus, prostate cancer hormonal therapy may increase breast cancer risk. A 67-year-old man with prostate cancer history presented with rising prostate-specific antigen level. F-Fluorocholine PET/CT showed intense uptake in his right breast and moderate uptake in right axillary lymph node. Complementary F-FDG PET/CT demonstrated more intense tracer uptakes in both the right breast and axillary lymph node...

Interpretation of iodine I whole-body scintigraphy can be challenging, as there are many nonpathologic findings that may present with increased radiotracer uptake. Radiotracer uptake has been reported in the literature involving the salivary glands, thymus, renal cysts, skin contamination, and other benign etiologies. We present the case of an incidental right wrist ganglion cyst demonstrating persistent increased uptake on I whole-body scintigraphy.

BACKGROUND: The etiology of HaNDL is not known. Recent neuroimaging studies have suggested that there may be altered cerebrovascular blood flow during acute episodes. However, what exactly these vascular changes represent and how they may relate to the overall pathogenesis of HaNDL is uncertain. CASE: A 42-year-old, right-handed male, presented with acute aphasia and right arm weakness. Urgent CT/CT-angiogram were normal except for an incidental hypoplastic right anterior cerebral artery (ACA) A1 segment...

STUDY OBJECTIVE: The aim of this study is to determine if the introduction of a pan-scan protocol during the initial assessment for blunt trauma activations would affect missed injuries, incidental findings, treatment times, radiation exposure, and cost. METHODS: A 6-month prospective study was performed on patients with blunt trauma at a level 1 trauma center. During the last 3 months of the study, a pan-scan protocol was introduced to the trauma assessment. Categorical data were analyzed by Fisher exact test and continuous data were analyzed by Mann-Whitney nonparametric test...

Human papillomaviruses (HPVs) are the etiologic agents of cervical cancer, the unique human neoplasia that has one single necessary cause. The diversity of HPVs is well described, with 200 HPV types existing as distinct taxonomic units and each receiving an Arabic number. On a clinical basis, they are usually grouped by their site of occurrence and disease associations. Those types inhabiting the anogenital mucosa are more intensively studied and further divided into cancer-associated HPVs, which are termed 'high risk', while those linked to benign proliferative lesions are assigned as 'low risk'...

The Ixodidae include the most common tick species encountered in Europe. The ticks transmit a variety of bacterial and protozoan agents of medical and veterinary significance. The aim of the current work was to investigate distribution of Ixodes ricinus and Dermacentor reticulatus ticks in Kyiv, the largest and most densely populated megapolis of Ukraine. Ticks were collected at various recreational areas by flagging during May, the month that showed the highest tick abundance in the past. Sex distribution among I...

Accessory muscles are relatively rare anatomic duplications of muscles that may appear anywhere in the muscular system. Though a wide array of accessory and supernumery muscles involving the ankle have been described in the literature, this is the first reported case we are aware of that features two accessory muscles. Accessory muscles are typically asymptomatic and often picked up as incidental findings but are important to be identified in the presence of chronic persistent ankle pain and the absence of other more common aetiologies...

OBJECTIVE: To evaluate the performance of contrastenhanced ultrasound (CEUS) in the risk stratification of indeterminate renal lesions picked up incidentally on abdominal imaging, in patients with renal impairment. METHODS: A retrospective study was performed of nonconsecutive patients who underwent CEUS at our tertiary care centre for indeterminate renal lesions between March 2010 and September 2014. A total of 63 patients with 74 nodules were assessed with CEUS and stratified into either benign (Bosniak I, II, IIF) or suspicious for malignancy (Bosniak III, IV or hypervascular solid lesions)...

Safety learning describes the ability to learn that certain cues predict the absence of a dangerous or threatening event. Although incidental observations of activity within the default mode network (DMN) during the processing of safety cues have been reported previously, there is as yet no evidence demonstrating that the DMN plays a functional rather than a corollary role in safety learning. Using functional magnetic resonance imaging and a Pavlovian fear conditioning and extinction paradigm, we investigated the neural correlates of danger and safety learning...

IgG4-related disease (IgG4-RD) is a fibroinflammatory condition that can affect practically every organ. Although it was first identified in pancreas and salivary glands, major organs like liver, biliary tree, kidney, thyroid glands and lungs are commonly involved, sometimes resulting in organ failure. We describe a case of an 41-year-old man presented with back pain after a rotator cuff injury. A Computed Tomography (CT) revealed incidentally a right lower lobe paravertebral lesion extending across the T5 and T6 vertebral levels and invading into the adjacent pleural surface...
