Abstract: We evaluated the ultrasonographic findings and performed ultrasonography-guided fine-needle aspiration biopsy of a newly detected nodule in the thyroid bed of 38 patients with postoperative thyroid carcinoma. Detection of a marginal irregularity, microcalcification, or a shape not parallel to the surrounding tissue plane might allow the identification of recurrent thyroid carcinoma from other benign pathologies mimicking local tumor recurrence.

Abstract: We report three cases of branchial cleft anomalies demonstrated by multidetector computed tomography (MDCT) fistulography. Multiplanar reformatted images using MDCT were excellent in delineating the whole fistulous tract and its surrounding structures. MDCT fistulography was very helpful in the diagnosis and surgical planning for sinus and fistula of branchial cleft anomalies. [Copyright &y& Elsevier]

Abstract: We describe MR imaging features of discal cyst of the lumbar spine in nine patients who presented with low back pain and leg pain. Discal cyst of the lumbar spine has characteristic MR imaging features different from other epidural cysts: a ventrolateral extradural cyst attached to a herniated lumbar disc, consisting of a thick fibrous capsule without disc material, and having occasional extension into the lateral recess with rim enhancement on contrast-enhanced MR imaging.

For categorizing the presenting neurological symptoms in Takayasu''s arteritis (TA) and correlating to the imaging findings of cerebral angiography, we retrospectively reviewed the angiographies of 27 patients presented with stroke, transient ischemic attack (TIA), visual disturbance, and/or dizziness. Neurological manifestations of TA resulted from decreased blood flow due to a steno-occlusive lesion and/or shifting of blood flow, thromboembolism, or hypertension. The pattern analysis of neurological manifestations related to specific arterial involvement is mandatory in understanding neurological manifestations of this systemic disease.
