Magnetic Resonance Imaging (MRI) has been the primary imaging modality and has revolutionized the imaging of brain tumors. MRI can display accurate multi planer imaging without interfering of adjacent structures specially for posterior fossa mass lesion. MRI is the imaging modality of choice for cerebollo-pontine (CP) angle Schwannoma. The study was performed to determine, the diagnostic accuracy of MRI in the evaluation of intracranial extra axial CP angle Schwannoma. MRI scan of brain was done on 42 consecutively selected patients referred for the evaluation of CP Acoustic Schwannoma. The age range from 21-60 years and the mean age was 42.85(+9.5) years. Highest incidence of cerebollo-pontine angle (CPA) mass were found 42.86% in 41-50 age group of patients. Male and Female ratio was 1.083:1. The most common presenting feature of the patients with CP angle Acoustic Schwannoma were headache 90.48%. Acoustic Schwannoma is T 1 hypointense 100%, T 2 hyper intense 84.61% and heterogeneously hyper intense 92.30% in FLAIR image. After giving contrast agents, homogeneous enhancement 57.69% and heterogeneous 42.31% cases of Acoustic Schwannoma. Overall 61.54% Acoustic Schwannoma strong contrast enhancement was observed. Dural tail was observed in 26.92% cases. Perilesional edema was observed 38.46% cases. Mass effect was observed in 76.92%. After complete MRI evaluation 61.9% had Acoustic Schwannoma. Histopathologicaly proved cases showed out of all patients Acoustic Schwannoma 59.52%. The overall sensitivity of MRI to diagnose Acoustic Schwannoma were found, Sensitivity-96%, Specificity-88.2%, PPV-92.31%, NPV-93.75% and Acceuracy 92.86%. Test is significant with p<0.0001 level. It is conceivable that MRI is a highly accurate, sensitive and Gadolinium enhanced MRI is more sensitive in detection of acoustic Schwannoma. MR imaging is the study of choice for the examination of the patient of cerebellopontine angle Schwannoma because of its high sensitivity specially after use of contrast material.
Fine needle aspiration (FNA) is a method of taking cytology sample by means of a fine needle attached with a syringe. Fine needle aspiration cytology (FNAC) is a diagnostic technique which involves study of the cell smears prepared from FNA material. [4][5][6] Ultrasound guided FNAC has been used as a diagnostic procedure of peripheral lung masses 7-9 but deep intrathoracic masses cannot be imaged by ultrasonography.CT guided biopsy was first reported in 1976 and since then numerous reports have shown CT guided transthoracic FNAC to be an accurate
This cross sectional study was carried out in the department of Radiology and Imaging, Dhaka Medical College Hospital from July 2008 to June 2010 to compare the accuracy of transvaginal ultrasonography and transabdominal ultrasonography in the diagnosis of clinically suspected cases of ectopic pregnancy. Initially 60 patients with clinical suspicion of ectopic pregnancy were included in this study after analyzing selection criteria 30 patients underwent both transvaginal and transabdominal ultrasonography. 'Histopathological diagnosis' was considered gold standard against which accuracies of two diagnostic modalities were compared. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of transabdominal ultrasonography as a diagnostic modality in evaluation of suspected ectopic pregnancy were 73.1%, 75%, 95%, 30% and 73.3% respectively where as transvaginal ultrasonography was found to have 92.3% sensitivity, 75% specificity, 96% positive predictive value, 60% negative predictive value and 90% accuracy. Transvaginal ultrasonography was superior to transabdominal ultrasonography in the evaluation of suspected ectopic pregnancies .so, transvaginal ultrasonography is important for early and accurate diagnosis of ectopic pregnancy.
The post partum diastasis ( means separation) of pubic symphysis is an uncommon disease. It causes acute pelvic pain. Manual pressure to the pelvis in a latero-lateral and antero-posterior direction worsens the condition. The diagnostic test for this condition is an anteroposterior X-ray of the pelvis. Here we present a case following spontaneous vaginal delivery. The conservative treatment is able to obtain good results. If this disease is underestimated the patient can develop chronic pain.CBMJ 2013 Jan:
The objective of the study was to find out the prevalence of gallbladder carcinoma in patients having cholelithiasis. For this purpose a prospective study was carried out on 15 patients of both sexes in Shaheed Ziaur Rahman Medical College Hospital, Bogura. Their mean age was 56 ±8 years (range 30 to 70 years) having gall bladder mass. Gall bladder mass and stone were detected by history, Physical examination, ultrasonography and computed tomography of the abdomen. Carcinoma was confirmed by histopathological examination of specimens removed by operation. All gallbladder masses removed by operation showed malignat tumor on histopathological examination. Among them adenocarcinoma and squamous cell carcinoma were present in 94 and 6 percent respectively. Stones were present within gallbladder mass in 94 percent of cases. In 80 percent of cases the disease was in advanced stage. The results of the present study suggested that the patient having cholelithiasis are prone to develop malignancy in the gallbladder. However as the sample size is small further studies are needed by taking large number of sample to validate this statement Journal of Surgical Sciences (2012) Vol. 16 (2) : 68-70
