Pneumothorax after transthoracic needle biopsy of lung lesions under CT guidance.

Transthoracic needle biopsy (TTNB) is done with imaging guidance and most frequently by a radiologist, for the aim is to diagnose a defined mass. It is integral in the diagnosis and treatment of many thoracic diseases, and is an important alternative to more invasive surgical procedures. FNAC is a method of aspiration cytopathology, which with transthoracic biopsy ("core biopsy") is a group of percutaneous minimally invasive diagnostic procedures for exploration of lung lesions.

Core needle biopsy of spinal lesions under CT guidance: review of 79 cases.

The authors report the results of a retrospective study about computed tomography (CT)-guided percutaneous vertebral biopsies in 79 cases (44 males and 35 females, aged from 6 to 84 years old). Five biopsies were performed at the cervical level, 31 at the thoracic, 30 at the lumbar, and 13 at the sacrum. A diagnosis was obtained in 75 out of the 79 patients.

Dural lesions mimicking meningiomas: A pictorial essay.

The purpose of this essay was to illustrate the radiological and pathological findings in a wide spectrum of dural lesions mimicking meningiomas. Familiarity with and knowledge of these findings will narrow the differential diagnosis and provide guidance for patient management. In this pictorial review, we describe the following entities: Solitary fibrous tumors, hemangiopericytoma, gliosarcoma, leiomyosarcoma, dural metastases, Hodgkin's disease, plasmocytoma, Rosai-Dorfman disease, neurosarcoidosis, melanocytic neoplasms and plasma cell granuloma.
