Since, the swelling was confined to soft tissue, contrast enhanced Magnetic Resonance Imaging (MRI) was advised which showed a peripheral rim enhancing, large, multilobulated T1WI hypointense and T2WI hyperintense lesion in right posterior chest wall having multiple internal septations. The lesion was involving the intercostal space and intercostal muscles. Cortical irregularity and altered marrow signal intensity was noted at 6 th and 7 th ribs of right posterior chest wall. Similar characteristics lesion was noted in the right posterior pleural space which appeared communicating with the posterior chest wall lesion. Ultrasound (US) examination of the swelling was done which showed hypoechoic, multi lobulated mass which showed no vascularity on color flow. Hence, ultrasound guided fine needle aspiration (FNA) was done; from which thick purulent yellowish colored pus was aspirated and was sent for gram stain, acid fast bacillus, culture and sensitivity. Pus culture revealed Mycobacterium tuberculosis. Based on this, thoracotomy with decortication was done. Patient was treated with intravenous antibiotics and discharged home on oral antibiotics with significant improvement (Figure 1 & Figure 2).

Objective: This study was undertaken to see the clinicalpathological characteristics of endometrial hyperplasia. Methodology: This cross sectional study was carried out from January 2007 to December 2008 for a period of two years. All suspected cases of endometrial hyperplasia were included for this study. Transvaginal sonography (TVS) performed and confirmation was done by histopathological examination. Result: A total number of 40 cases were enrolled for this study. The most common diagnosed endometrial pathology was endometrial hyperplasia which was 42.5% cases. Endometrial polyp was diagnosed in 32.5% cases. Endometrial carcinoma was in 7.5% patients and submucosal fibroid was in 10.0%. Conclusion: Endometrial hyperplasia is the most common disease among the women presented with endometrial pathology.

In this situation, histocytopathological analysis is needed to conrm the diagnosis by CTguided biopsy / FNAC. So, the researcher purposively, designed this study. The aim of this study was to assess the outcomes of CT-Guided Fine-Needle Aspiration Cytology and Core Needle Biopsies of Solitary Lung Lesions. CT-uoroscopy guidance helps in this process by accurate needle positioning thus increase the success rate. Materials and Methods: This was a retrospective study conducted at the Department of Radiology & Imaging in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, during January 2017 to January 2019.Atotal of 270 patients who were referred to the Department of Radiology& Imaging for the evaluation of suspicious solitary lung lesions after the detection of a solitary pulm...

Variable imaging characteristics in conjunction with clinical findings can facilitate early diagnosis and treatment. MRI is a powerful imaging tool that can be help to evaluate spinal pathology specially infection. Typical MRI findings of infective vertebral disease are vertebral endplate destruction, bone marrow and intervertebral disc signal intensity changes and para vertebral soft tissue involvement. Objective: This study was aimed to assess whether the MRI can different the in differentiate the invective vertebral lesions from benign or malignant Tumors. Methods: This cross-sectional study was conducted on a total of 52 clinically suspected patients of infective vertebral lesions to establish diagnostic accuracy of MRI. The validity of MRI diagnosis for infective vertebral lesion was compared against CT-guided fine needle aspirati...

It results from clonal proliferation of histiocytes having similar morphology and immunophenotype to Langerhans cells in skin and mucosa Though head and neck manifestation is common, isolated simultaneous bilateral temporal bone Langerhans Cell Histiocytosis is an extremely rare presentation. Having same otological menifestations, high resolution CT scan is advocated for early identification and differentiation of LCH from other common conditions such as mastoidits,otitis externa ,chronic suppurative otitis media. Diagnosis of LCH is confirmed by biopsy and immunohistochemical staining of S-100 protein and or CD1a antigen. Chemotherapy is main mode of treatment.The prognosis is worse when presenting age of children is younger than 2 years. Bangladesh J Otorhinolary...

This cross- sectional study was carried out to assess the diagnostic usefulness of Duplex Color Doppler sonography in the evaluation of asymptomatic carotid atherosclerosis in prediction of silent cerebral infarction. Nature of extracranial carotid plaque and degree of luminal stenosis were compared & associated with MRI findings and risk factors of silent cerebral infarction. Method: This cross sectional study was carried out in the Radiology & Imaging Department of Dhaka Medical College Hospital during th...
