@entity3 along the needle track ( @entity19635 ) after a @entity1610 ( @entity1610 ) is considered a very rare complication. A survey of the membership of the Society of Thoracic Radiology and a review of the English-language literature were conducted to assess the incidence of this complication and its predisposing factors and natural history. A questionnaire was sent to all radiology departments in the United States and Canada that had a senior member of the Society of Thoracic Radiology. The total number of @entity1610 between 1978 and 1993 and occurrences of @entity19635 were elicited. If an @entity19635 was encountered, information on the size of the nodule, proximity to the pleura, histology, size of the biopsy needle, and the interval between biopsy and @entity19635 and outcome of the @entity1 was elicited. The incidence of @entity19635 was estimated using binomial proportions. Results of the literature survey were tabulated to provide similar information. One hundred sixty-five questionnaires were mailed and 75 responses were received. Approximately 68,346 @entity1610 were reported. Five departments reported a total of eight @entity19635 , resulting in an incidence of 0.012%. The average interval between @entity1610 and @entity19635 was 2.6 months. There were no predictable risk factors. The outcome was known in only 11 @entity1 ; 4 @entity1 died by the time of reporting (2 after 14 months and 1 each after 6 and 9 months). From the results of this survey, the incidence of @entity19635 after @entity1610 is approximately 0.012%. This small risk is random and unavoidable.
