Anti-allergic house of 4,8-sphingadienine stereoisomers inside vivo and in vitro design.
Metatropic dysplasia (MD) is a rare skeletal disorder characterized by short stature due to epiphyseal cartilage and growth plate abnormalities. The severity of MD varies from mild to lethal. This disorder is caused by mutations in the transient receptor potential vanilloid 4 (TRPV4) that encodes calcium-permeable, nonselective cation channels. A 33-year-old female presented at our hospital with a history of worsening knee pain diagnosed at the previous institution as a case of osteoarthritis. Radiographs of the knee showed epiphyseal irregularity without joint space narrowing. On MRI, fat-suppressed proton density-weighted imaging revealed thickened articular cartilage with a smooth surface and an abnormal signal intensity of the subchondral bone; T 1 weighted imaging demonstrated irregularity of the epiphysis. These findings and the familial history (both her children had TRPV4 mutations) led to the suspicion that her condition could be due to mosaicism for TRPV4 mutation. To the best of our knowledge, this is the first report of MRI findings focusing on articular cartilage thickening in a patient with mild MD. Bone dysplasia including MD should be considered in young patients with articular cartilage thickening and subchondral bone irregularities on MRI.We present a unique case of inflammatory pseudotumour involving gluteal subcutaneous tissue with the sparing of superficial fat and report its contrast-enhanced CT, F-18 fluorodeoxyglucose positron emission tomography/CT and pathological findings. Although rare, inflammatory pseudotumours have been reported with a diverse spectrum of locations; however, the involvement of the subcutaneous tissue overlying the gluteal muscles with sparing of the most superficial fat has not been reported.We report a case of prune perineum syndrome, an extremely rare entity with only four cases reported to date, describing some typical clinical and radiologic features. We also present a newly associated imaging finding, the terminal ventricle's cystic dilatation, and briefly discuss the differential diagnosis.Venous tumour thrombosis refers to the invasion of tumour into the venous system. Extramural venous invasion is routinely searched for and reported in rectal carcinoma due to its prognostic significance and influence on staging, prognosis and treatment approach. We describe a case of extramural venous invasion occurring as superior mesenteric vein tumour thrombus in the setting of a caecal carcinoma.Coronary artery anomalies are rare; however, can be a potential cause of significant morbidity and even mortality. Crossed left anterior descending and left circumflex arteries is a rare finding, and therefore the significance of this finding is not well understood. CT coronary angiography is an excellent non-invasive modality which enables the diagnosis of such abnormalities, and it is likely that with the increased use of CT coronary angiography in cardiology, other similar cases will be diagnosed.Desbuquois dysplasia is an autosomal recessive chondrodysplasia characterized by severe micromelic dwarfism, joint laxity, progressive scoliosis, and advanced carpotarsal ossification. Two different types of Desbuquois dysplasia have been identified according to the presence (Type 1) or absence (Type 2) of characteristic hand abnormalities including bifid distal thumb phalanx, an extra ossification center distal to the second metacarpal, and interphalangeal joint dislocations. Further, Kim et al have described a milder variant of Desbuquois dysplasia characterized by short stature and hands with short metacarpals, elongated proximal and distal phalanges, and extremely advanced carpal ossification. Here, we present a 19-year-old male patient with Kim variant of Desbuquois dysplasia. He displays almost all of the characteristic skeletal findings of Desbuquois dysplasia along with the characteristic hand features described by Kim et al. This patient is unique in that he also presents sagittal femoral bowing, a radiographic finding that accompanies various skeletal dysplasias but has never been reported in a patient with Desbuquois dysplasia to date.Cervical spondylotic myelopathy (CSM) is a clinical syndrome secondary to a spinal cord compression due to cervical spondylosis. In some cases, conventional MRI typically shows an intramedullary hyperintense signal on T2W imaging and contrast enhancement on post-gadolinium T1W imaging. We report a series of seven patients with CSM who had typical clinical presentation and imaging findings on T2W and contrast-enhanced T1W sequences. The imaging findings included degenerative changes of the cervical spine, intramedullary T2-signal hyperintensity, and an intramedullary enhancement on post-gadolinium T1W images. Our results support the statement that the presence of an intramedullary gadolinium-enhancement with a flat transverse pancake-like pattern (on sagittal images) and a circumferential pattern (on axial images), located within a T2-signal abnormality, in patients with cervical spondylosis and clinical myelopathy is indicative of spondylosis as the cause of the myelopathy.Acute appendicitis (AA) is one of the most common causes of acute abdominal pain and it generally affects young males in the second or third decade of their life. Due to its often insidious presentations, the diagnosis is challenging and, if delayed, can lead to life-threatening complications. This report describes a rare case of an almost asymptomatic complicated appendicitis caused by an appendicolith followed by spontaneous detachment of the vermiform appendix and its complete colliquative necrosis with abscess formation. Thus far this is the first case of spontaneous appendix avulsion in an adult where the appendix is entirely colliquated into an abscess.Cystic lesions in relation to the pericardium are a rare congenital lesion with an estimated incidence of 1 per 100,,000. Pericardial cysts may be classified as congenital or acquired. Here, we present a case of a pericardial pseudocyst having a horseshoe configuration along the atrioventricular groove in a middle-aged subject with no previous relevant medical history. VY-3-135 The patient underwent open surgery for the same with histopathological diagnosis being established. This paper highlights the differentials for a cystic pericardial lesion in imaging in addition to the histopathological entity of a pericardial pseudocyst.
