Abstract Background Protracted febrile myalgia syndrome (PFMS) is a rare complication of Familial Mediterranean fever (FMF). The diagnosis is based on clinical symptoms and is often challenging, especially when PFMS is the initial manifestation of FMF. The aim of this report was to describe the magnetic resonance imaging (MRI) findings in pediatric patients with PFMS. Results There were three girls and two boys ranging in age from 6 months to 16 years, all of Mediterranean ancestry. Three had high-grade fever, and all had elevated inflammatory markers. MRI of the extremities yielded findings suggestive of myositis, which together with the clinical picture, normal CPK levels, and supporting family history of FMF, suggested the diagnosis of PFMS. Out of most common MEFV mutations tested, one patient was homozygous for M694V mutation, three were heterozygous for M694V mutation, and one was compound heterozygous for the M694V and V726A mutations. Conclusions MRI may serve as an auxiliary diagnostic tool in PFMS.

Rheumatoid meningoencephalitis (RM) is a rare complication of rheumatoid arthritis (RA). This report describes a 63-year-old man with complaints of high-grade fever, headache, and vomiting for several days before admission. Both his serum and cerebrospinal fluid were positive for anti-cyclic citrullinated peptide (CCP) antibody and rheumatoid factor, and contrast-enhanced fluid-attenuated inversion recovery magnetic resonance imaging (MRI) showed abnormal gadolinium enhancement of the meninges and high-intensity lesions in the subarachnoid spaces. The patient was diagnosed with RM despite lack of signs suggesting RA. His symptoms drastically improved with intravenous infusion of high-dose methylprednisolone. Two months later, he developed RA. The findings in this patient suggest that RM could develop prior to the onset of RA. Anti-CCP antibody and MRI findings may be useful for the diagnosis of RM, regardless of RA history.

Background: Cutis Verticis Gyrata (CVG) is a rare skin disease caused by overgrowth of the scalp, presenting as cerebriform folds and wrinkles. CVG can be classified into two forms: primary (essential and non-essential) and secondary. The primary non-essential form is often associated with neurological and ophthalmological abnormalities, while the primary essential form occurs without associated comorbidities. Discussion: We report on a rare case of primary essential CVG with a 4-year history of normal-colored scalp skin mass in the parietal-occipital region without symptom in a 34-year-old male patient, retrospectively summarizing his pathological and Computer Tomography (CT) and magnetic resonance imaging (MRI) findings. The major clinical observations on the CT and MR sectional images include a thickened dermis and excessive growth of the scalp, forming the characteristic scalp folds. With the help of CT and MRI Three-dimensional (3D) reconstruction techniques, the characteristic skin changes could be displayed intuitively, providing more evidence for a diagnosis of CVG. At the 5-year followup, there were no obvious changes in the lesion. Conclusion: Based on our observations, we propose that not all patients with primary essential CVG need surgical intervention, and continuous clinical observation should be an appropriate therapy for those in stable condition.

Balo’s concentric sclerosis (BCS) is a rare demyelinating disease known as Multiple Sclerosis (MS) lesion type III. It is a disease of the white matter of the brain characterized by a round lesion with variable concentric myelinated and demyelinated layers, appearing as “onion bulb.” We present a case of BCS and discuss the imaging findings and management strategies of this disease. A 26-y-old male developed headache, weakness, and numbness of limbs. Magnetic resonance imaging (MRI) showed concentric lamellar like demyelinating lesions at the subcortical regions. The patient’s neurological symptoms were consistent with the MRI findings.

AbstractWe investigated the prevalence of magnetic resonance imaging (MRI) findings and their relationship with knee symptoms in women without radiographic evidence of knee osteoarthritis (KOA). This cross-sectional cohort study included 359 Japanese women without radiographic evidence of KOA (Kellgren‒Lawrence grade < 2). All participants underwent T2-weighted fat-suppressed MRI of their knees. Structural abnormalities (cartilage damage, bone marrow lesions [BMLs], subchondral cysts, bone attrition, osteophytes, meniscal lesions, and synovitis) were scored according to the whole-organ MRI score method. Knee symptoms were evaluated using the Knee Injury and Osteoarthritis Outcome Score. Participants were divided into early and non-KOA groups based on early KOA classification criteria. Logistic regression analysis was performed to evaluate the relationship between MRI abnormalities and knee symptoms. Cartilage damage was the most common abnormality (43.5%). The prevalences of cartilage damage, BMLs, subchondral cysts, bone attrition, meniscal lesions, and synovitis were higher in patients with early KOA than in those without. Synovitis (odds ratio [OR] 2.254, P = 0.002) and meniscal lesions (OR 1.479, P = 0.031) were positively associated with the presence of early KOA. Synovitis was most strongly associated with knee pain and might be a therapeutic target in patients with early KOA.

Background: Vaginal adenosis is a rare clinicopathological entity which refers to the presence of glandular endometrial tissue in the vaginal wall. Case report: A gravida 46-year-old woman was presented to the gynecology department with symptoms of chronic pelvic pain. Maternal Diethylstilbestrol (DES) usage has been proven effective in the development of vaginal adenosis. It can also be idiopathic. Its sonographic or magnetic resonance imaging (MRI) findings have not been described in English literature previously. Conclusion: Here, we report the clinical, transperineal ultrasonographic (US) and MRI findings of a pathologically proven case of vaginal adenosis.

ABSTRACT The aim of this report was to describe the magnetic resonance imaging (MRI) and pathological features of a canine mixed glioma. A 12-year-old boxer male dog was presented for necropsy along with data from an MRI evaluation conducted ante-mortem. The images were examined and showed a poorly demarcated prosencephalic lesion, hyperintense on T2W images, hypointense on T1W images and heterogeneously hyperintense on T2W FLAIR images. There was mild nonuniform contrast enhancement, apparent midline shift, moderate perilesional edema and marked distortion of the adjacent lateral ventricle. The brain was evaluated macroscopically, microscopically and immunohistochemically. Grossly, there was a poorly demarcated soft mass, with areas of hemorrhage, within the left parietal and temporal lobes. Histologically, there was a densely cellular mass composed of two geographically distinct populations of neoplastic cells. The first population was composed of small and round cells organized in a honeycomb pattern. The second population constituted of intermingled streams and bundles of neoplastic cells that were strongly immunolabeled for glial fibrillary acidic protein (GFAP). The diagnosis of a mixed glioma was based on MRI findings, and mainly on histological and immunohistochemical findings.

Introduction: We aimed to introduce the diagnostic value of diffusion-weighted (DWI) magnetic resonance imaging (MRI) for distinguishing benign and malignant renal cystic masses.Methods: Abdominal DWI-MRIs of patients with Bosniak categories 2F, 3, and 4 cystic renal masses were evaluated retrospectively. Cystic masses were assigned as benign or malignant according to histopathological or followup MRI findings and compared with apparent diffusion coefficient (ADC) values.Results: There were 30 patients (18 males and 12 females, mean age was 59.23 ± 12.08 years [range 38‒83 years]) with cystic renal masses (eight Bosniak category 2F, 12 Bosniak category 3, 10 Bosniak category 4). Among them, 14 cysts were diagnosed as benign and 16 as malignant by followup imaging or histopathological findings. For the malignant lesions, the mean ADC values were lower than for benign lesions (p=0.001). An ADC value of ≤2.28 x10-6 mm2/s or less had a sensitivity of 75% and a specificity of 92.86% for detecting malignancy.Conclusions: ADC can improve the diagnostic performance of MRI in the evaluation of complex renal cysts when used together with conventional MRI sequences.

Objectives: The purpose of this study was to investigate the correlation between grades of endolymphatic hydrops (ELH) and clinical characteristics and determine the detailed clinical characteristics of Ménière’s disease (MD) patients with evidence of hydrops based on magnetic resonance imaging (MRI). Methods: One hundred ninety-eight MD patients (396 ears) with MRI evidence of hydrops were included. ELH grades were evaluated using the Nakashima grading standard. Correlations between the extent of ELH and clinical features were evaluated. Detailed clinical characteristics were analyzed to assess the clinical diagnostic criteria. Results: Of 198 patients, ELH was observed in 100% of cases on the clinically affected side and 8.6% of cases on the asymptomatic side. In addition, 98.5% of ELH was classified as moderate or significant grade. Low-frequency hearing loss was significantly correlated with the extent of both vestibular and cochlear hydrops, whereas the vertigo attack frequency showed no significant correlation with ELH grades. The disease duration of MD with bilateral ELH was longer than that with unilateral ELH. The clinical characteristics were variant and did not completely fit the proposed diagnostic criteria. Conclusions: MRI findings have relevance to the clinical severity, to a certain extent, but not vestibular symptoms. The proposed diagnostic criteria based on clinical characteristics may be partially effective; analysis of the detailed clinical characteristics of MD was meaningful. Diagnosis of MD based on both MRI and clinical symptoms could facilitate an early diagnosis.
