Osteopoikilosis; a rare incidental spotted bone disease on CT

Osteopoikilosis is a benign, asymptomatic, sclerosing bone dysplasia with an autosomal dominant trait. The disease is characterized by diffuse symmetrical small round and ovoid radiopacities in the juxta-particular region of cancellous bone. We reported a rare case of a middle aged female presented with abdominal distension, whose radiological work up revealed an incidental osteopoikilosis

Significance of sonographic characterization and fnac of small size thyroid nodules

The purpose of this study is to determine the accuracy of various ultrasound characteristics of small size thyroid nodules in the predication of malignancy and the usefulness of ultrasound guided FNAC of these nodules. Experimental / analytic study. This study was carried out at Radiology Department Services Hospital, Lahore from October 2011 to September 2012. This study was conducted on 70 patients, in whom 76 thyroid nodules 4mm to 10mm in size were biopsied. Diagnostic ultrasound was performed with high frequency linear probe for the evaluation of following ultrasound characteristics, internal structure, echogenicity, margins, posterior acoustic shadowing, height to width ratio, halo around the nodules, calcifications and vascular flow on Doppler scan. Each character was correlated with the results of FNAC to determine the accuracy of the feature in the prediction of malignancy. Out of 76 FNACs of 4mm to 10mm size thyroid nodules 8 [10.5%] biopsies did not yield significant cytological specimen. Another 8 [10.5%] specimen were classified as indeterminate so no further analysis was done. The rate of malignancy among nodules on final diagnosis was 20%. The most accurate sonographic features associated with malignancy were posterior acoustic shadowing [88.3%], taller than wider [83%], Halo around the nodule [80%] and calcification [70%]. Small size thyroid nodules are associated with significant risk of malignancy. Certain sonographic characteristics can be used to measure the risk of malignancy. FNAC of these nodules can be safely and accurately performed with high diagnostic rate

CT findings of a giant retroperitoneal liposarcoma; our experience at services hospital, Lahore

Liposarcoma is the most common primary neoplasm of mesodermal origin derived from adipose tissue. It is a slow-growing tumor with a propensity to displace rather than invade adjacent structures. This article reports the CT findings of retroperitoneal liposarcoma in one patient. CT scan revealed a huge hypodense expansile mass lesion with multiple hyperdense septation inside it, giving a whorly appearance to the mass. The mass was having mainly fat [attenuation. The mass appeared to be extending from the under surface of right hemidiaphragm to the right iliac fossa. The mass displaced all the abdominal viscerae and major vessels to the left side of the abdominal cavity, origin being retroperitoneum with most probable epicenter in right renal fossa
