ABSTRACTWe report an unusual case of unilateral limb pseudo hypertrophy in a 21-year-old lady who developed progressive enlargement of the right calf followed by thigh in association with chronic leg pain. Magnetic resonance imaging (MRI) of the affected limb confirmed enlargement of various muscles. Electromyography revealed neurogenic features consistent with S1 radiculopathy. MRI of the lumbosacral spine showed tethered cord with a lipoma infiltrating multiple sacral roots. Our case illustrates that muscular pseudo hypertrophy may follow chronic denervation as a consequence of spinal neural compressive disease. The various mechanisms postulated for this distinct condition are outlined.

Abstract A 54-year-old man with a right hemiparesis was found to have an intrasellar intercarotid communicating artery associated with agenesis of the right internal carotid artery. Magnetic resonance imaging (MRI) studies demonstrated the spatial relationship of the anomalous artery to the surrounding structures, thus suggesting an embryonic enlargement of the capsular artery as a source of this anomalous artery.

This paper reports an unusual case in which aseptic meningitis presented with sudden sensorineural hearing loss (SSNHL) associated with intralabyrinthine haemorrhage (ILH). A seven-year-old girl presented with sudden right-sided hearing loss with dizziness. She did not have a previous history of bleeding disorders. This child was assessed using audiograms and magnetic resonance imaging (MRI). The patient's hearing loss was irreversible. Steroid therapy was not effective. SSNHL associated with ILH can be one of the negative prognostic factors in children.

In vivo dynamic changes in the interosseous membrane (IOM) during forearm rotation were studied using magnetic resonance imaging (MRI). The right forearms of 20 healthy volunteers were examined in five different rotational positions. Axial slices were obtained at the proximal quarter, the middle and the distal quarter of the forearm. The changes in shape of the IOM during rotation were observed in an axial MR plane. For each image, we measured the interosseous distance and the length of the interosseous membrane. Images of the tendinous and membranous parts of the IOM could be differentiated by thickness. There were minimal dynamic changes in the tendinous part on the MRI while the membranous part showed numerous changes during rotation. The interosseous distance and the length of the interosseous membrane were maximum from a neutral to a slightly supinated position. The tendinous part is considered to be taut during rotation to provide stability between the radius and the ulna, but the membranous part which is soft, thin and elastic, allows smooth rotation.

AbstractWe present our experience using the Clarion® magnetless multichannel cochlear implant with a woman profoundly deafened following bilateral acoustic neuromata as a consequence of neurofibromatosis 2 (NF2). The right neuroma had been previously removed without an attempt at neural preservation. On the left, however, a posterior fossa approach had been taken with the aim of preserving hearing. Although the left cochlear nerve appeared to be undamaged at the end of the operation, no hearing thresholds could be elicited on post-operative audiometry, because of damage either to the cochlear nerve or to the blood supply to the cochlea. Round window electrical stimulation subsequently produced a perception of sound, confirming that the cochlear nerve was capable of functioning and that a cochlear implant would be effective. Because she would need regular magnetic resonance imaging (MRI) to monitor existing and future NF2 lesions, it was decided to use a magnetless Clarion® implant, which has been shown to be MRI compatible. We report our experience of using the device in this case and discuss some of the issues related to the provision of cochlear implants to patients with NF2.

The multiseptate bladder is a congenital bladder anomaly that is very rare and often accompanied by other congenital abnormalities. This condition could result in intravesical obstruction and kidney failure in more serious conditions. A 3-year-old girl without any complaint was consulted by the Pediatric Surgery Department with postoperative cloacal type malformation anorectal (MAR) postero-sagittal anorecto-vagino-urethroplasty (PSARVUP) + sigmoidectomy. Magnetic Resonance Imaging (MRI) of the pelvis showed the appearance of four interconnected multiple fluid lesions. Cystoscopy was performed and found many septa with varied positions and forms. From the cystography during the operation, it was seen duplication of the right and left bladder. There was no further operative treatment in the field of urology because no urinary tract obstruction and normal renal function were found in this study.

Abstract Background: Nowadays, it needs favorable biomarkers to follow up the disease progression and therapeutic responses of Duchenne muscular dystrophy (DMD). This study evaluates which one of Quantitative muscle ultrasound (QMUS) and magnetic resonance imaging (MRI) is suitable for the disease in China. Methods: Thirty-six boys with DMD engaged in the longitudinal observational cohort study, who used prednisone from baseline to 12th month. Muscle thickness (MT) and echo intensity (EI) of QMUS and T1-weighted MRI grading were measured in the right quadriceps femoris of the boys with DMD. Results: The scores of MT and EI of QMUS and T1-weighted MRI grading showed significant correlations with the clinical ones of muscle strength, timed testing, and quality of life. The scores of MT and EI of QMUS showed good correlations with the ones of T1-weighted MRI grading too (P<0.05). But 15 of 36 boys with DMD did not take MRI examinations for different reasons. Conclusions: QMUS and MRI can use as biomarkers for tracking DMD. Nevertheless, QMUS, because of its practical, low cost, and patient-friendly, applies for DMD widely than MRI in China.

Gall bladder (GB) may be found in a variety of abnormal positions. Most of them are due to arrested development of embryonic growth at different stages. A 63-year-old female patient was admitted to our radiology unit for magnetic resonance imaging (MRI) of the liver for the lesions identified in abdominal ultrasonography (US) and computed tomography (CT). MRI showed that there was a lobulated heterogenous mass in the left lobe of the liver and a smaller one in the right lobe of the liver with the same appearance. The inferior pole of the liver was located in the pelvic space, and the GB, which contained sludges and stones, was lying down to the upper pelvic space. Hepatic masses were considered to be hemangiomas, and GB was diagnosed as ptotic GB with luminal sludge and stones. In this case, especially, MR imaging helped the surgeon to plan a proper approach to the GB in abnormal localization.

Ventricular septal defect (VSD) is a congenital heart disease that accounts for up to 40% of all congenital cardiac malformations. VSD is a connection between right and left ventricle, through the ventricular septum. Echocardiography and magnetic resonance imaging (MRI) help identify this entity. This case presents a 12-year-old male diagnosed with a small muscular apical VSD of 3 mm in diameter, at echocardiography. Cardiac MRI using first-pass perfusion sequence, combining the right plane of acquisition with a short bolus of contrast material, clearly confirmed the presence of VSD.

Idiopathic orbital pseudotumor (IOP) is a benign inflammatory condition of the orbit without identifiable local or systemic causes. Bilateral massive orbital involvement and extraorbital extension of the IOP is very rare. We present an unusual case of IOP with bilateral massive orbital infiltration extending into maxillofacial regions and discuss its distinctive magnetic resonance imaging (MRI) features that help to exclude other entities during differential diagnoses.

The use of magnetic resonance imaging (MRI) in pigmented villonodular synovitis (PVS) has been well described in the literature. MRI has been used predominantly with diffuse PVS lesions. We recently had a patient with an unusual case of localized PVS of the ankle with bone and cartilage destruction. Preoperative MRI was useful in the diagnosis of localized PVS and in the planning for surgery. MRI in a patient with this lesion had not been documented previously, but should be considered whenever PVS, either diffuse or localized PVS, is suspected.
