Primary lymphoma of the cervix

A 62-years old female presented with postmenopausal vaginal bleeding for one month. On vaginal examination soft fungated mass was palpated in cervix that bled to touch. Ultrasound, CT scan and MRI showed well-defined mass in cervix. On biopsy it was proved to be a primary non-Hodgkin's lymphoma

Ultrasound differentiation of bening versus malignant solid breast masses

To determine the reliability of ultrasonographic features in differentiating benign from malignant solid breast masses. Design: Descriptive, analytical study. Place and Duration of Study: Radiology Department, Aga Khan University Hospital, Karachi from July 2000 to June 2002. Subjects and One hundred solid breast masses in females with a tissue diagnosis available were reviewed. Two radiologists reviewed the sonographic features of masses without knowledge of clinical history or histologic examination results. Ultrasound features were corrected later with histologic features to determine the reliability of the former in benign or malignant nature of nodules. Ultrasound features that most reliably characterize masses as benign were a round or oval shape, circumscribed margins and a width to antero-posterior [AP] dimension ratio greater than 1.4. Features that characterized masses as malignant included irregular shape, spiculated margins and width to antero-posterior [AP] dimension ratio of 1.4 or less. If these three most reliable criteria had been strictly applied by the primary reporting radiologist, the overall cancer biopsy yield would have increased. The data confirms that certain ultrasound features can help differentiate benign from malignant masses. However, practice and interpreter variability should be further explored before these criteria are applied to defer biopsy of solid masses

Accuracy of magnetic resonance imaging in the knee

To determine the accuracy of magnetic resonance imaging [MRI] in the assessment of various knee disorders in comparison with arthroscopic findings and pathologic diagnosis. Design: A retrospective and comparative study. Place and Duration of Study: Radiology Department, Aga Khan University Hospital, Karachi, from 01-12-1996 to 30-06-2000. Patients and Fifty-six subjects [36 males and 20 females], included in this study, had abnormal findings on MRI, which were correlated with arthroscopic findings in 50 cases and pathological diagnosis in 6 cases. Plain X-rays were available in all cases. The sensitivity, specificity and accuracy for MRI of the menisci and cruciate ligaments were as follows: medial meniscus pathologies 87% sensitivity, 94% specificity and 92% accuracy; lateral meniscus pathologies 92% sensitivity, 89% specificity and 90% accuracy; anterior cruciate ligament injuries 95% sensitivity, 96% specificity and 96% accuracy and posterior cruciate ligament injuries 100% sensitivity, 98% specificity and 98% accuracy. Pathological diagnosis was available in 6 cases. MR imaging suggested the diagnosis of tuberculosis and metastases as well as mapped out the extent of osteogenic sarcoma, fibromatoses and rhabdomyosarcoma. This study confirms that MR imaging of the knee is highly sensitive, specific, and accurate

Gossypiboma - A case report

Gossypiboma [retained surgical sponge] is a rare occurrence and can occur after any surgical procedure, which requires the use of internal swabs. We present a case of 40 years old female who underwent laparotomy for hysterectomy. This case is presented to highlight the fact that this condition should always be included in the differential diagnosis of patients who have had previous surgery and vague symptoms
