A unique case of a serous borderline tumor of the paratestis.

Serous borderline tumors of the paratestis are histologically identical to their ovarian counterparts and hypothesized to arise from Mullerian metaplasia of the tunica vaginalis. They are exceedingly rare with many cases probably going clinically unnoticed. We present a case of serous borderline tumor of the paratestis, with, to the best of our knowledge, the first published sonographic and magnetic resonance (MR) images of this entity.

Specimen adequacy and diagnostic specificity of ultrasound-guided fine needle aspirations of nonpalpable thyroid nodules.

Ultrasound-guided fine needle aspiration (USG-FNA) is a safe, effective, and dependable test used to assess thyroid nodules. However, the size of the lesion can adversely affect the outcome of the procedure. The aim of this study was to assess specimen adequacy and diagnostic specificity in USG-FNA of thyroid nodules measuring < or = 1.

Resistive indices in the evaluation of infants with obstructive and nonobstructive pyelocaliectasis.

Diagnosing obstructive uropathy by renal resistive indices calculated from duplex Doppler sonographic waveforms has been supported as well as challenged in the radiology literature relating to adults. Despite reports of normally higher resistive indices in children as compared to adults, two studies have documented high sensitivity and specificity of renal Doppler sonography in the diagnosis of obstructive uropathy in children, using the same discriminatory criterion of a resistive index of 0.7 or greater as used in adults.

Complications of prostate cryosurgery: CT findings in three patients.

We present the computed tomographic (CT) findings of complications of prostate cryosurgery in three patients. One patient had injury to the bladder base and rectum, which resulted in ureteral obstruction and vesicorectal fistula. The other two patients had urethral injuries.
