Myelography and residual contrast in panoramic radiography: case report

ABSTRACT Myodil or pantopaque is an oil-based contrast solution often used up to 1980 for myelography, cisternography, and ventilography. Oilbased contrasts have a very slow clearance time in the cerebrospinal fluids and may encapsulate for decades and remain in the central nervous system and the in...

Zusammenfassung:ABSTRACT Myodil or pantopaque is an oil-based contrast solution often used up to 1980 for myelography, cisternography, and ventilography. Oilbased contrasts have a very slow clearance time in the cerebrospinal fluids and may encapsulate for decades and remain in the central nervous system and the interior of the spine. The knowledge of the existence of this rare condition coming from other radiographictests of the past, described in this clinical case, is essential when atypical radiographic images are found. RESUMO O myodil ou o Pantopaque é uma solução de contraste a base de óleo usada frequentemente até 1980 para mielografia, cisternografia e ventilografia. Os contrastes à base de óleo têm um tempo de liberação muito lento nos fluidos cefalorraquidianos e podem encapsular por décadas e permanecer no sistema nervoso central e no interior da coluna vertebral. O conhecimento da existência dessa condição rara proveniente de outros exames radiográficos do passado, descritos neste caso clínico, é essencial quando são encontradas imagens radiográficas atípicas, principalmente em radiografia panorâmicas.
