Loeffler Endocarditis

Loeffler endocarditis is rare and can initially be a clinically silent cardiac disorder. Given its natural history with evolving stages and its vague initial cardiac presentation, it is important to keep this as a differential diagnosis. Without treatment, this disorder is progressive and may lead to a possible restrictive cardiomyopathy-related heart failure. Here, a rare case who presented with nonspecific chest pain is reported, which was recognized early by a routine noninvasive transthoracic echocardiography (TTE) imaging study. This was followed by the addition of contrast enhancement techniques, which made it possible to solidify the diagnosis of the mass to a right ventricular thrombus (possibly secondary to the hypereosinophilia syndrome), with isolated right ventricular involvement. Magnetic resonance imaging (MRI) of the heart, without contrast, was performed to further analyze the anatomic location of this entity. A high index of suspicion for Loeffler endocarditis helped identify this condition.

Abstract Background Mature presacral (retrorectal) teratoma is very rare. We report a case in which a mature retrorectal teratoma in an adult was successfully treated with laparoscopic surgery. Case presentation A 44-year-old woman was diagnosed with a presacral tumor during a physical examination. Endoscopic ultrasonography (EUS) revealed a multilocular cystic lesion; the lesion was on the left side of the posterior rectum and measured approximately 30 mm in diameter on both contrast-enhanced pelvic computed tomography (CT) and magnetic resonance imaging (MRI). The presumptive diagnosis was tailgut cyst. However, the histopathological diagnosis after laparoscopic resection was mature teratoma. It is still difficult to preoperatively diagnose mature retrorectal teratomas. Conclusions Laparoscopic resection of mature retrorectal teratomas is a feasible and promising method that is less invasive and can be adapted without extending the skin incision.

Abstract Background Early diagnosis of meningitis with magnetic resonance imaging (MRI) would be useful for appropriate and effective management, decrease morbidity and mortality, and provide better diagnosis and treatment. The objective of the current study is to compare the accuracy of contrast-enhanced FLAIR (CE-FLAIR) and contrast-enhanced T1WI (CE-T1WI) in the detection of meningeal abnormalities in suspected cases of meningitis. Results Out of 45 patients, 37 patients were confirmed to have meningitis on CSF analysis. Out of the 37 patients, 34 patients were positive on CE-FLAIR sequence and 27 were positive on CE-T1WI. The sensitivity of CE-FLAIR sequence was 91.9% and specificity 100%, while the sensitivity of CE-T1WI sequence was 73% and specificity 100%. Conclusion CE-FLAIR is more sensitive than CE-T1WI in diagnosis of meningitis. It is recommended to be used in any cases with clinically suspected meningitis.

Improving Patient Care

Magnetic resonance imaging (MRI) has become an indispensable tool in the assessment of malignant disease. With increasingly sophisticated systems and technical advancements, MRI has continued to expand its role in providing crucial information regarding cancer diagnosis and management. In gynecological malignancies, this modality has assumed greater responsibility, particularly in the evaluation of cervical and endometrial cancers. In addition to conventional imaging, innovative techniques such as dynamic contrast-enhanced MRI and diffusion-weighted MRI show promise in offering early assessment of tumor response. This paper reviews the current role of MRI in gynecological cancers and highlights the potential of novel techniques in improving patient care.

LF thickening has a predominant tendency to occur specifically at the T10–T11 level. This may be due to maximum tensile strength and mobility at this level.

Ménière’s disease (MD) is characterized by intermittent episodes of vertigo with fluctuating sensorineural hearing loss, tinnitus, and aural fullness. Despite numerous studies, the etiology of this disorder remains poorly understood and thus diagnostic criteria are mainly clinical. Development and progress in magnetic resonance imaging (MRI) techniques, in 2007, has enabled visualization of endolymphatic hydrops, which was the milestone achievement. We present two cases of patients with clinically confirmed MD with a set of audiological, otoneurological examinations and MRI performed. Structures of the inner ear were visualized using contrast-enhanced MR imaging after a 4-hour delayed intravenous gadolinium administration. The cochlea and vestibule were evaluated separately and classified using Barath grading scale. Endolymphatic hydrops in the clinically affected ears was confirmed using MRI. Due to disabling and intractable MD, a decision about vestibular neurectomy was made.

SynopsisMany structural brain abnormalities have been described in schizophrenia, consistent with a neurodevelopmental model for this disease. We report here a study of the cavum septum pellucidum (CSP) in schizophrenia compared to control groups, as well as the clinical correlates of this congenital anomaly in schizophrenia. We conducted a magnetic resonance imaging (MRI) study to compare rates of CSP in schizophrenia (N = 67) v. psychiatric controls (bipolar and schizoaffective, N = 60) and healthy controls (N = 37). Of the controls 18·9 %, and of all psychotic subjects 18·1 % had a CSP of any size and there was no difference in the frequency of large CSP among the groups. Males had higher rates of CSP than females (25% v. 9·7%, P = 0·01) in all groups. Schizophrenics had higher CSP rates than affective patients (25%, v. 10%, P = 0·02). No clinical difference was found between schizophrenics with or without CSP.
