conclusions ct epidurography is not closely correlated with a clinical assessment of epidural block; thus, a clinical assessment of the sensory block is mandatory. the use of opioid analgesia in combination with local anesthetics may compensate for the lack of efficacy of local anesthetics alone. objectives the primary objective of this study was to evaluate, by ct imaging and digital multiplan...

A 39-year-old Japanese man presented to our hospital complaining of left chest pain and rash on the hands and feet. Plain thoracic computed tomography (CT) revealed multiple nodular shadows in the left lower lobe of the lung. A diagnosis of secondary syphilis was made based on the appearance of the rash and positive serologic tests for syphilis. The patient was started on amoxicillin but was sw...

objective(s): in this study, we aimed to analyze the relationship between the diagnostic ability of fused single photon emission computed tomography/computed tomography (spect/ct) images in localization of parathyroid lesions and the size of adenomas or hyperplastic glands. methods: five patients with primary hyperparathyroidism (phpt) and 4 patients with secondary hyperparathyroidism (shpt) we...

nutcracker syndrome (ncs) is a rare pathology, caused by compression of the left renal vein (lrv) between the abdominal aorta (aa) and the superior mesenteric artery (sma), due to reduction of the angle between aa and sma. this leads to lrv varices, left gonadal vein varices and therefore, the pelvic congestion syndrome. for this reason, coexistence of ncs and pelvic congestion syndrome has bee...

introduction: cauda equina secondary to metastatic follicular thyroid cancer of the lumbosacral area is a rare entity.   case report: we report an unusual case of a 52-year-old male who presented with backache, lower limb weakness, and perianal numbness. a ct-scan of the lumbosacral area showed an enhancing mass at the l4, l5 and s1 vertebrae. histopathology after excision revealed a metastatic...

Venous sinus thrombosis is a relatively uncommon disorder that frequently is associated with confusing clinical findings and delayed diagnosis. Patients are often screened with unenhanced CT, and CT findings may be subtle and may include hyperattenuation of cerebral veins or venous sinuses secondary to intracranial thrombosis. This hyperattenuation may be mimicked by polycythemia, as shown in t...

OBJECTIVE To investigate and analyze the typical CT findings of salivary gland lymphoepithelial carcinoma. METHODS CT findings in 8 patients with lymphoepithelial carcinoma (LEC) in salivary gland were studied retrospectively. Surgical resection was performed in all cases. RESULTS 8 cases were subdivided to primary tumor and secondary tumor. In primary tumor group, 5 were localized in the p...

The purpose of this study is to determine the incidence and significance of incidental findings on pediatric oncologic PET/CT. A retrospective analysis of all PET/CT scans obtained at Helen DeVos Children’s Hospital between 2004-2008 in pediatric oncology patients was performed. Specific data points for study including DOB, primary diagnosis, secondary diagnosis, treatment status (chemotherapy ...

Metastatic tumors or secondary lymphoma of the kidney are rare and can often be missed on conventional computed tomography (CT) imaging. On the other hand, many types of metastatic tumor or lymphoma can be detected clearly as hotspots of elevated uptake on FDG PET. However, excreted FDG present in the urinary tract mimics these findings and interferes with image reading. Careful investigation o...

PURPOSE To describe the in vivo CT appearance of acute intracerebral blood clots formed from anemic platelet-depleted blood. METHODS Three patients with intracerebral hemorrhage secondary only to thrombocytopenia were examined with CT within 2 1/2 hours after the onset of clinical symptoms. RESULTS There were no unusual CT features found in the intracerebral hemorrhages of patients with onl...
