RESUMO
Objective: To determine the CT patterns of temporal bone cholesteatoma in patients presenting with chronic discharge from ear
Methodology: This was a cross-sectional study conducted at Department of Radiology, Rehman Medical Institute Peshawar from January 2013 to June 2014. 78 patients with chronic discharging ear, who were referred from E.N.T outpatient department, were included in the study. All scans were performed on 128 slice Multidetector Computed tomography [MDCT] scanner.O.Smm reconstructed images in bone window and 3mm images in soft tissue window were viewed on 5.1 vitrea workstation in axial, coronal and sagittal planes. The CT studies were correlated with clinical examination findings, surgical and histopathology. Basic radiologic patterns of cholesteatoma described on CT scan were assessed. The data was processed using Microsoft excel 2007
Results: Cholesteatoma was present in 48 [61%] cases. The disease was bilateral in 7 cases [14 %], 39 [81 %] were unilateral. 25 [52%] were left sided and 14 [29%] right-sided. 24 [30 %] patients were characterized as having otomas-toiditis whereas 7[8%] patients were radiologically difficult to characterize if they were cholesteatoma or not
Conclusion: Cholesteatomas can cause bone erosions and should be detected early. The important role of MDCT lies in the early detection of cholesteatoma, and more conservative surgical procedures can be used to eradicate the disease
RESUMO
This case report is of a 50 years old female who presented with vague history of long term abdominal pain, shortness of breath and echocardiographic suspicion of right atrial mass. She was investigated using 128-slice Multidetector Computed tomography [MDCT] scanner in the Department of Radiology
Images of lower chest, entire abdomen and pelvis were taken in venous phase. On CT images of our patient, uterus was significantly enlarged and replaced by multiple contour deforming fibroids, which were involving the right ad-nexa, invading the right ovarian vessels, and extending into the right ovarian vein, inferior vena cava [IVC] and right atrium of heart
The findings were confirmed on surgery. Surgery also confirmed extension into right ventricle and pulmonary arteries i.e. pulmonary leiomyomatosis emboli. The histologi-cal findings were consistent with intravascular leiomyoma. MDCT images play instrumental role for preoperative morphologic assessment of IVL as it can easily identify the precise location, extent and provide a roadmap for the surgeons
RESUMO
Objective: to characterize, diagnose and to differentiate various HRCT manifestations of lung abnormalities in post chemotherapy patients
Methodology: this was a retrospective study of 50 patients conducted at Ra-diology department of Rehman Medical Institute, Peshawar. Duration of study was 6months i.e from April 2013 to September 2013. Patients were investigated using 128-slice Multidetector Computed tomography [MDCT] scanner in the Radiology department of Rehman Medical Institute Peshawar. 0.5mm reconstructed images in lung window and 3mm images in mediastinal window were viewed on workstation in axial, coronal and sagittal planes. The data was processed using Microsoft excel 2007
Results: a total of 50 patients were included. Age of the patients ranged from 6 to 70 years with a mean age of 35 years. In our study, we found five radiologic patterns on CT scan; [1]non-specific ground-glass attenuation 17[34%],[2] patchy distribution of ground-glass attenuation accompanied by interlobular septal thickening 7[14%], [3]multifocal areas of airspace consolidation 7[14%],[4]extensive bilateral ground-glass attenuation or airspace consolidations with traction bronchiectasis 4[8%], and [5] nodules of variable sizes randomly distributed in both lungs 15[30%]
Conclusion: the most common pattern was found to be patchy areas of ground-glass attenuation. Pulmonary diseases that are induced by chemotherapy represent particular challenges for radiologists due to non-specific and atypical imaging features
