Cardiac masses are rare entities that can be challenging in clinical diagnosis and management. Cardiac masses can be detected incidentally in patients with an asymptomatic course or may cause ...systemic inflammation findings due to inflammatory cytokine release or symptoms such as shortness of breath, chest pain, syncope, sudden cardiac death, and mortality due to the location of the mass. Cardiac masses associated with systemic inflammatory disorders are uncommon in this disease group. This case report will present a case with an asymptomatic IgG4-related left atrial mass detected in routine echocardiographic control imaging due to rheumatic valve disease.
Background
Langerhans cell histiocytosis (LCH) is an abnormal polyclonal proliferation of Langerhans cells that affect different parts of the body. Temporal bone involvement is quite common among the ...involved sites. The etiology is unknown. Diagnosis is based on symptoms, imaging, and histopathology. Especially LCH in temporal bone is confused with acute or subacute otitis media. There are many treatment options in LCH.
Case presentation
Here, a 2-year-old pediatric patient with pain in the right ear was diagnosed as having LCH as a result of the examinations. MRG revealed multiple lesions in the temporal bone, sphenoid bone, and clivus. She was treated with steroids and vinblastine.
Conclusion
Possible tumoral formations should be kept in mind when children complain of otalgia and otitis media-like clinical picture for a long time.
Chondroblastoma is a rare cartilaginous benign bone tumor. Chondroblastoma in the temporal bone is also quite rare. Total excision is the main treatment. Data regarding tumor response to radiation ...therapy (RT) is insufficient. We describe a case of chondroblastoma that was treated with RT following subtotal tumor resection. In this case, the patient was a 14-year-old male who presented with a three-month history of ear fullness and hearing loss in his right ear. Magnetic resonance imaging revealed a mass partly filling the right external auditory canal and the inferior part of the middle ear. Histopathological findings indicated chondroblastoma. Subtotal tumor resection was performed due to risk of complications. RT was planned upon the growth of the tumor during follow-up. Treatment with subtotal resection and postoperative RT has been successful and the patient had no recurrence in the course of the 12-year follow-up. In chondroblastoma, complete surgical resection is still the gold standard. But the success of subtotal resection followed by adjuvant RT should also be kept in mind for cases where the total excision would pose high morbidity.

We aimed to evaluate the frequency and features of dual left anterior descending artery (LAD) variants using computed tomography (CT) angiography.
A total of 1337 consecutive coronary CT angiography ...examinations performed between April 2010 and December 2013 were retrospectively evaluated for the presence of dual LAD. CT examinations were performed with either 64- or 320-row multidetector CT scanners. All CT angiography images were evaluated for the presence and morphologic features of dual LAD subtypes.
Fifty-six dual LAD variations (4%) were identified in this study population. Type 1 was the most common type of dual LAD (n=48), while Type 3 (n=3) and Type 4 (n=2) were infrequent and Type 2 was not detected. Additionally, we detected previously unclassified dual LAD variations in three cases.
Dual LAD may be a relatively more common variant than described in the medical literature, which is mostly based on catheter angiography studies. Coronary CT angiography seems markedly efficacious for detecting and documenting the anatomical details of dual LAD subtypes, as well as showing other associated cardiocoronary anomalies.
Although technological improvements have increased, EVAR is still not free of complications during or after EVAR-procedure. Infection complication during EVAR is considered quite rare, and ...contamination during the procedure is proposed the foremost reason. Radiological evidence such as the presence of air bubble within the excluded aneurysmal sac in the early post-procedure period of endovascular aneurysm repair (EVAR) might be an important finding of infection, even in the absence of any symptoms; and thereby, it should be monitored closely. Keywords: Endovascular aneurysm repair, air bubble within the excluded aneurysmal sac, early post-procedure period.
Objectives: The current study evaluates the value of cardiac hybrid imaging (CHI), performed by the fusion of functional and anatomic cardiac images, in the detection of hemodynamically significant ...coronary stenosis in cases with multiple coronary stenosis. Methods: A total of 36 patients (10 female, 26 male) in whom ischemia or infarction was detected on gated myocardial perfusion single photon emission computed tomography (gMPS) and multiple coronary stenosis were concomitantly detected on coronary computed tomography angiography (CCTA) and undergone invasive coronary angiography (ICA) was included in this study. Statistical analyses were performed using SPSS 22 Windows software. McNemar test was applied to show concordance between coronary CT angiography, ICA and CHI in the detection of anatomically or hemodynamically significant stenosis in three major coronary arteries. Comparison results of coronary arteries responsible for perfusion defects on CHI and gMPS are presented as percentages (%). Results: There was total accordance between coronary arteries leading to perfusion defects detected by gMPS and CHI in 50% of patients. It was observed a partial accordance in 36.1% of the patients. Additionally, it was also detected perfusion defects originated from side branches in 25% of the patients. Between results of CCTA and ICA, no statistically significant difference was noted in the detection of anatomically significant stenoses in the left main coronary artery, left anterior descending artery (LAD), left circumflex artery (LCx) and right coronary artery (RCA) (p=1.000, 0.070, 0.549, and 1.000, respectively). In addition, no statistically significant difference was found in the detection of anatomically and hemodynamically significant stenoses in LAD, LCx and RCA by CCTA and CHI (p=0.344, 0.629, and 0.219, respectively). No statistically significant difference was observed in the detection of anatomically and hemodynamically significant stenoses in LAD, LCx and RCA by ICA and CHI (p=0.804, 1.000, and 0.344, respectively). Conclusion: It is possible to detect hemodynamically significant coronary stenosis directly by CHI modality in patients with multiple coronary stenosis, wide perfusion defects.
Cardiac computed tomography (CT) is most commonly performed for the evaluation of the coronary arteries; however, non-coronary cardiac pathologies are frequently detected on these scans. In cases ...where magnetic resonance imaging cannot be used, cardiac CT can serve as the first-line imaging modality to evaluate many non-coronary cardiac pathologies. In this article, we discuss congenital non-coronary abnormalities of the left heart and their cardiac CT imaging features.
