Eleven children with craniocerebral neuroblastoma (three primary and eight metastatic) were examined by computed tomography (CT). The findings in both primary and secondary neuroblastoma correlate well with the known neuropathologic findings. Primary cerebral neuroblastoma originates in the brain parenchyma of the supratentorial space, and may extend into the cerebrospinal fluid pathways. Secon...

A 25-year-old man was admitted in hospital due to right side hemopneumothorax secondary to car accident. A chest tube was inserted. During the hospitalization days, chest CT scan revealed a 3cmx3 cm oval-shaped density located in the right upper lobe. Since he was in a good general condition, he was discharged from hospital after removal of chest tube and a follow-up chest CT-scan was recommend...

Unenhanced computed tomography (CT) is currently being widely used for the evaluation of patients presenting with acute flank pain. A variety of primary and secondary findings detected on unenhanced CT contribute not only to the diagnosis but also to the treatment plan. This review includes primary and secondary multidetector CT imaging findings of urinary stone disease, potential pitfalls with...

Aliphatic amines, such as n-hexylamine (primary), di-n-hexylamine (secondary) and tri-n-hexylamine (tertiary amine), react with tetrabromophenolphthalein ethyl ester molecules (TBPEH) to form reddish or red-violet charge-transfer complexes (CT complexes) in 1,2-dichloroethane (DCE). The absorption maxima of the CT complexes with all primary amines occur at around 560 nm, with secondary amines a...

The secondary pulmonary lobule is a fundamental unit of lung structure, and it reproduces the lung in miniature. Airways, pulmonary arteries, veins, lymphatics, and the lung interstitium are all represented at the level of the secondary lobule. Several of these components of the secondary lobule are normally visible on thin-section computed tomographic (CT) scans of the lung. The recognition of...

BACKGROUND The aim of this study was to evaluate potential benefits of a new diagnostic software prototype (Trauma Viewer, TV) automatically reformatting computed tomography (CT) data on diagnostic speed and quality, compared to CT-image data evaluation using a conventional CT console. METHODS Multiple trauma CT data sets were analysed by one expert radiology and one expert traumatology fello...

Spinal nerve root or cauda equina compression in patients with leukemia is often secondary to extradural chloroma [1]. We present the CT myelographic findings of an intradural mass and lumbar nerve root enlargement secondary to leukemic infiltration of the lumbar subarachnoid space and nerve roots. This form of leukemic involvement of the nervous system has not previously been demonstrated with...
