ABSTRACT

This paper highlights an uncommon complication of a percutaneous transthoracic needle biopsy (PTNB). A patient with rheumatoid arthritis who was on immune suppressive drugs underwent a PTNB of a lung nodule. The histology showed “organizing usual interstitial pneumonia-like changes.” Unfortunately, one month after the PTNB, she developed a large deep-seated chest wall abscess at the biopsy needle tract and the previously seen lung nodule was larger. Nocardiosis sp. was isolated from the chest wall abscess. The lung and chest wall lesions were resolved with Bactrium and Fluconazole. The final diagnosis was pulmonary nocardiasis complicated by chest wall seeding following the PTNB procedure.

ABSTRACT

PURPOSE: Inconclusive results from computed tomography (CT)-guided transthoracic needle aspiration and biopsy (TNAB) performed for lung lesions presents a clinical dilemma. The purpose of this study was to determine the factors affecting an inconclusive result from a CT guided TNAB, and to evaluate the final outcomes of these inconclusive results. MATERIALS AND METHODS: The medical records and radiologic features of 331 patients with lung lesion who received CT guided TNAB were analyzed retrospectively. The results of the TNAB were classified as conclusive (malignancy or specific benign diagnosis) or inconclusive (nonspecific benign or nondiagnostic). RESULTS: Of the 331 cases, 269 (81.3%) were diagnosed as a malignancy (210) or a specific benign lesion (59) after the first TNAB. The remaining 62 (18.7%) were inconclusive. Benign disease, a lesion size < or =15 mm, and morphology of the consolidation type were features significantly correlated with inconclusive results. Of these 62 inconclusive cases a second TNAB was performed in 23, and conclusive diagnoses were obtained in 19 (82.6%). Surgery or radiographic follow up was done in other cases. Finally, among the 62 inconclusive results on the first CT guided TNAB, 16 lesions were diagnosed as malignant, 26 were classified as specific benign disease, and the remaining 20 were defined as nonspecific inflammation. Age over 50 and morphology of a nodule or a mass type were significantly correlated with a malignancy in these 62 cases with inconclusive results on the first TNAB. CONCLUSION: A final diagnosis of benign disease was significantly higher after the CT guided TNAB was inconclusive for lesions < or =15 mm that had consolidation type morphology. Despite the application of core biopsy procedures, there continue to be appreciable numbers of inconclusive results after the first CT guided TNAB. A repeat CT guided TNAB had a high diagnostic yield in these cases and therefore should be considered for cases with inconclusive results.

ABSTRACT

CT-guided transthoracic needle biopsy is a common procedure for the evaluation of pulmonary and mediastinal lesions. The most frequent complications include pneumothorax, hemorrhage, and hemoptysis. Air embolism especially cerebral embolism is rare but potentially fatal complication after this procedure. Here, we report a case of cerebral air embolism occurred after CT-guided transthoracic needle biopsy for the peripheral lung mass.

ABSTRACT

Since Virchow first introduced the term myxoma to describe a tumor that recapitulates the structure of the umbilical cord, it has been increasingly recognized that many diverse neoplasms may acquire a similar myxoid appearance. Myxoma have evolved within the pathology literature from tumors often described in practically all sites to the currently recognized subtypes restricted to the heart, skin, soft tissue, and bone. Pulmonary myxoma is extraordinary rare. We experienced pulmonary myxoma in a 63 year old man. The pulmonary radiology showed mass in right upper lung field, and percutaneous transthoracic needle lung biopsy was performed to confirm the myxoma.
