RATIONALE: The efficacy of direct oral anticoagulants (DOACs) in the treatment and prophylaxis of cancer-related venous thromboembolism (VTE) is reportedly similar to that of heparin. However, the effect of DOACs on the prophylaxis of cancer-related arterial thromboembolism (ATE) remains unclear. To our knowledge, we present the 1st case where cerebral ATE was encountered during edoxaban administration for VTE in a patient with lung adenocarcinoma. PATIENT CONCERNS: In March 2017, a 63-year-old female was diagnosed with lung adenocarcinoma (cT2aN3M1b stage IVa) along with having asymptomatic VTE; thus, 60 mg/day edoxaban administration was initiated...

BACKGROUND: Maternofetal carnitine transport through the placenta is the main route of fetal carnitine uptake. Decreased free carnitine levels discovered by newborn screening has identified many asymptomatic adult women with systemic primary carnitine deficiency (PCD). Here, we presented amplitude integrated electroencephalogram (aEEG) and magnetic resonance imaging (MRI) findings from a neonate with epilepsy whose mother was carnitine deficient. CASE PRESENTATION: A one-day-old female newborn was admitted after experiencing seizures for half a day; status epilepticus was found on the continuous normal voltage background pattern with immature sleep-wake cycling during aEEG monitoring...

The gold standard for clinical assessment of Autism Spectrum Disorders (ASD) relies on assessing behavior via semi-structured play-based interviews and parent interviews. Although these methods show good sensitivity and specificity in diagnosing ASD cases, behavioral assessments alone may hinder the identification of asymptomatic at-risk group. Resting-state functional magnetic resonance imaging (rs-fMRI) could be an appropriate approach to produce objective neural markers to supplement behavioral assessments due to its non-invasive and task-free nature...

Ectopic accessory thymic tissue usually presents as an asymptomatic neck mass found at any level corresponding to the embryonic descent of the thymus. This tissue may contain smaller or larger cysts. However, the exact pathogenesis of "enigmatic" cervical thymic cysts remains controversial. A 7-year-old boy was referred to our workplace for the evaluation of a cervical mass. An ultrasound suggested a multi-loculated cystic mass, while CT and MRI indicated a left-sided, anteriorly located cervical mass beneath the sternocleidomastoid muscle...

Multi-factorial causes jeopardize brain integrity in β-thalassaemia. Intracranial parenchymal and vascular changes have been reported among young β-thalassaemia patients but conventional magnetic resonance imaging (MRI) findings are contradictory making early MRI and magnetic resonance angiography (MRA)/venography monitoring a matter of debate. This study prospectively investigated 75 neurologically asymptomatic β-thalassaemia patients (mean-age 35·2 ± 10·7 years; 52/75 transfusion-dependent; 41/75 splenectomised) using a 3T magnetic resonance scanner; clinical, laboratory and treatment data were also collected...

BACKGROUND: There is no consensus on the appropriate surveillance for high-risk women with breast cancer in Japan. We investigated their imaging features and pathological characteristics to build a proper surveillance system for asymptomatic high-risk individuals in the future. METHODS: We retrospectively reviewed 93 female (median age 43 years) BRCA1 and BRCA2 mutation carriers from our institutional clinical database from 2011 to 2017. The study population was composed of 112 breast cancers...

X-linked adrenoleukodystrophy (x-ALD) is a rare genetic disorder caused by a mutation in the ABCD1 gene, which encodes for a peroxisomal very long chain fatty acid transporter. Clinically, x-ALD can present a wide spectrum of different phenotypes: asymptomatic carriers, Addison only, cerebral x-ALD, and myelopathy with/without evidence of peripheral axonopathy (Adrenomyeloneuropathy). We report on two cases of adult x-ALD, with atypical phenotypes: (Case 1) A 37-years-old male with a 2-years-long history of spastic paraparesis, urinary urgency, and subclinical adrenocortical insufficiency...

BACKGROUND Pituitary gland metastasis is rarely the initial presentation of metastatic cancer. Most cases of pituitary gland metastasis are asymptomatic with diabetes insipidus being the most common symptomatic presentation. It can rarely present with symptoms of hormone underproduction such as secondary adrenal insufficiency. Although pituitary gland metastasis is rare, it is underestimated, as it is commonly misdiagnosed with pituitary gland adenoma due to the lack of clear radiological criteria differentiating between both...

Introduction: Human parechovirus (HPeV) infections appear common across age groups, and transmission is likely fecal-oral and through respiratory secretions. Cyclical and seasonal patterns have been described; however, HPeV has likely been previously underdiagnosed due to lack of commercially available diagnostic testing. Presentation of Case: We present identical triplets contracting HPeV Type 3. Discussion: The clinical presentation, similar to echoviruses, is broad and includes asymptomatic shedding, severe pulmonary and neurologic disease, and disseminated intravascular coagulation...

BACKGROUND: Focal nodular hyperplasia (FNH) is a frequent benign liver lesion. Its course is considered benign, and there is no recommendation for its treatment. Nevertheless, the literature presents a high incidence of surgery. AIM: To evaluate the results of conservative treatment in a series of patients with presumed FNH. METHODS: The study included patients diagnosed with FNH from May 2007 to July 2017 based on conventional imaging or magnetic resonance imaging with liver-specific contrast (MRI-LSC) or lesion biopsy (histology/immunohistochemical analysis)...

BACKGROUND: Zinner syndrome represents a rare congenital malformation of the urinary tract. It comprises a constellation of Wolffian duct anomalies and is almost exclusively encountered as a classic triad of seminal vesicle cysts, ejaculatory duct obstruction and renal agenesis. Patients can be either asymptomatic or symptomatic. Recently, minimally invasive surgical techniques have emerged, superseding traditional surgery for select symptomatic cases. Our case highlights the finding of a rare clinical syndrome that was incidentally detected during a routine mass screening of military recruits in the Greek Armed Forces...

BACKGROUND: Deafness, autosomal recessive 77 (DFNB77) is a rare non-syndromic hearing loss (NSHL) worldwide, which is caused by deleterious variants within lipoxygenase homology domains 1 (LOXHD1). Here we identified that a novel missense variant of LOXHD1 was associated with NSHL in a Chinese family under consanguineous marriage. CASE PRESENTATION: A 28-year-old woman suffered a bilateral profound NSHL. Impedance audiometry, temporal bone computerized tomography (TBCT) scans and magnetic resonance imaging-inner ear hydrography (MRI-IEH) did not find any obvious abnormality of middle or inner ear...
