intracranial lipoma is an uncommon entity. a rare type of tumor in the internal auditory canal (iac) and the cerebellopontine angle (cpa) is lipoma. there are a few case reports in the literature related to intravestibular lipoma. herein, we report a case of lipomas within the cerebellopontine angle and vestibule of the inner ear in a patient with tinnitus and dizziness. the patient was evaluat...
results compared to pre-op scores, pf, ss, and vas scores for back, buttock and leg pain had a significant mean decrease at 6, 12, 24 months post-op (p < 0.05). based on the zcq and vas scores, a success rate of 79% (27.34), 78% (30.38) and 74% (17.23) were achieved at six months, 12 months, and 24 months respectively. conclusions x-stop is a safe and effective treatment for nic that provides m...
introduction cardiac hydatid cysts are rare and represent less than 2% of all hydatid cases. they can occur as part of a widespread systemic infection or an isolated event. case presentation here, we presented a case of cardiac hydatid cyst in interventricular septum. conclusions the case presented had some findings that suggested the specific diagnosis of hydatid cyst.
a 36-year-old woman, diagnosed with systemic lupus erythematosus (sle), showed bulbar symptoms including impaired memory, slurred speech and swallowing difficulty 7 days before admission. magnetic resonance imaging (mri) showed symmetric confluent hyperintensities in the bilateral cerebral white matter on t2 weighted imaging (t2-wi), extended into the genu of the internal capsule and the crus c...
در حال حاضر چندین روش برای اندازه گیری چربی زیرپوستی بدن در حوزه های بالینی وجود دارد ، مانند : magnetic resonance imaging(mri)، (computer tomography(ct، ultrasound imaging(us) ، dual energy x-ray absorptiometry(dexa). این روش ها بطور وسیعی در حوزه های بالینی به عنوان وسایل دقیق و مفید ، مورد استفاده قرار می گیرند. به هر حال این روش ها محدودیت های زیادی مانند هزینه بالا و یا خطر تابش اشعه را دا...
INTRODUCTION The vast majority of paratesticular masses are benign. Magnetic resonance imaging of the scrotum may provide valuable information in the pre-operative work-up of scrotal masses, by allowing the precise localization of the lesion and helping in characterizing its nature. Diffusion-weighted magnetic resonance imaging is an evolving technique that can be used to improve tissue charact...
basic physical principles of nuclear magnetic resonance imaging (n.m.r.i), a nonionizing medical imaging technique, are described. principles of nmri with other conventional imaging methods, ie, isotope scanning, ultrasonography and radiography have been compared. t1 and t2 and spin density (s.d.) factors and different image construction techniques based on their different combinations is discu...
brachial plexus injury (bpi) is an uncommon complication of median sternotomy capable of causing a permanent or transitory sensitivity and/or motor function impairment in the upper limbs. during a cardiac surgery through sternotomy, for the assessment of the thoracic cage configuration and the site of mediastinal structures, a broader surgical field may be required. if the sternal retractors ar...
