The purpose of this study was to report our centre's experience in the results and complications of percutaneous CT-guided lung biopsy. A retrospective review of 409 patients who underwent percutaneous CT-guided fine-needle aspiration of suspicious lung lesions for more than 5 years was carried out. Nodule sizes ranged from 0.6 to 10 cm. The calibre of the needle used was 21-23 G. Specimen adequacy and patient outcome were evaluated. Each case was reviewed for complications. Sufficient diagnostic material was obtained in 369 (90%) of the 409 fine-needle aspirations. Diagnosis was malignancy in 290 (70%) samples, four (1%) samples were suspicious for malignancy, 65 (16%) samples were negative for malignancy and definite benign findings were identified in 10 (3%) specimens. There were 25 false-negative cases and one false-positive case. Sensitivity was 92% and specificity 98%. Pneumothorax was the most common complication and occurred in 17 (4%) patients. Only one of them required thoracic drainage. Blood effusion around the lesion or along the needle track was detected on the post-biopsy CT in 8 (2%) patients. However, only one of them suffered from a mild haemoptysis. Percutaneous CT-guided biopsy is an effective and fast procedure for diagnosis of suspected pulmonary malignancy, with a low complication rate.
The FDG-PET/CT scan plays an important role in restaging breast cancer patients with rising tumor markers and negative or equivocal findings in conventional imaging techniques, with a consequent significant clinical impact on further management in these patients.
Primary non-Hodgkin's lymphoma of the esophagus is a rare disease. A case of primary isolated nonHodgkin's lymphoma of the esophagus in a 77-yearold man without acquired immunodeficiency syndrome is presented. We describe the clinical features and the imaging findings (barium swallow, endoscopic ultrasonography and CT) of a biopsy proven B-cell lymphoma with diffuse transmural involvement of the esophagus wall, which was discovered incidentally. We also briefly review the literature.
IntroductionLipomas can be found anywhere in the body with the majority located in the head and neck region as well as in the shoulder and back. They are not very common in the hand and those involving the fingers are very rare. Although, it is not the only case reported, lipoma of the index finger is very uncommon.Case presentationA 52-year-old Caucasian man presented with a lipoma of the right index finger. He complained of no pain but he had difficulty in manual movements. Treatment was surgical excision of the lipoma. There has been no recurrence for two years.ConclusionAlthough lipomas of the fingers are rare entities, their awareness is imperative since the differential diagnosis from other soft tissue tumors and from the special lipomatous subtype involved is quite extensive.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
