PURPOSE We aimed to evaluate the diagnostic accuracy and safety of computed tomography (CT)-guided biopsy of pulmonary lesions with fine needle aspiration (FNA) using non-coaxial technique. METHODS We analyzed 442 patients who underwent CT-guided lung biopsy with FNA and non-coaxial technique to determine the diagnostic outcomes, complication rates, and independent risk factors for diagnostic failure and pneumothorax. RESULTS Diagnostic accuracy, sensitivity, and specificity were 97.6%, 97.3%, and 100%, respectively. Age and >35 mm lesion size were significant risk factors for diagnostic failure. The rates of pneumothorax and chest tube placement were 19% and 2.9%, respectively. Middle and lower lobe location, lesion to pleura distance >7.5 mm, and >45° needle trajectory angle were significant risk factors for pneumothorax. CONCLUSION CT-guided FNA of pulmonary lesions with non-coaxial technique is a safe and reliable method with a relatively low pneumothorax rate and an acceptably high diagnostic accuracy.

Micro‐Abstract As mastectomy is known to effect body posture, we evaluated the long‐term physical effects of unilateral mastectomy on spine deformity by radiographic examination of 60 women taken before and 12 months after the mastectomy. The results indicated long‐term spinal deformation in women with unilateral mastectomy, suggesting informing patients of the possible change in body posture in the long‐term. Objective: Mastectomy is known to effect body posture after a change in the center of gravity of women due to a missing breast. Although previous studies on short‐term postural changes in mastectomy patients using photogrammetry or Moiré topography suggested ipsilateral inclination of the trunk, our clinical observations during breast reconstruction surgeries indicated a contralateral shoulder elevation in women with unilateral mastectomy. Because the change in body posture can affect spinal alignment, we aimed to evaluate the long‐term physical effects of unilateral mastectomy on spine deformity by radiographic examination. Methods: Posteroanterior chest radiographs of 60 women (mean age 56.3 ± 8.5 years) taken before and 12 months after the mastectomy were evaluated for Cobb angle and the presence or absence of a tilt from the midline in the coronal plane of vertebral body alignment. Results: Cobb angle decreased in 14 and increased in 38 of 60 patients after unilateral mastectomy, and the angular change was found to be independent of the mastectomy side (P < .001). A shift in Cobb angle to the mastectomy side was observed in 11 of 53 patients (P > .05), whereas a statistically significant shift in Cobb angle to the opposite of the mastectomy side was observed in 33 of 53 patients (P < .001). The results of this observational retrospective study indicated long‐term spinal deformation in women with unilateral mastectomy. Two patients with idiopathic scoliosis before mastectomy even developed scoliosis. Conclusion: We recommend informing the patients of the possible change in body posture in the long term, which should be supported or limited with physical therapy.

Summary Background Trifurcation of the common carotid artery is an unusual variation. Case Report We report a case of left common carotid artery trifurcation in a 74-year-old man. The left common carotid artery divided into the internal carotid, external carotid and facial arteries. Herein, the anatomy of the carotid arteries and the Doppler sonography and CT angiography findings of the left common carotid artery trifurcation were described with images. Conclusions The variations of the carotid arteries should be known to avoid and reduce the complications during the invasive procedures.

Summary Background Primary renal primitive neuroectodermal tumor/extraskeletal Ewing’s sarcoma (PNET/EES) is a very rare renal tumor. Case Report We report a case of primary renal PNET/EES of the kidney in an adult patient and describe its computed tomography and magnetic resonance imaging findings, including diffusion weighted images along with a review of the current medical literature. Conclusions Although very rare, a relatively large renal mass which shows very infiltrative growth pattern on CT and MR imaging and striking diffusion restriction should raise the suspicion of a renal primitive neuroectodermal tumor, in a young adult.

Summary Background Intranodal palisaded myofibroblastoma is a benign and very rare mesenchymal neoplasm of the lymph nodes originating from differentiated smooth muscle cells and myofibroblasts. Case Report We report a case of intranodal palisaded myofibroblastoma in an 84-year-old woman with Parkinson’s disease that presented as a left inguinal mass. The diagnosis was made using ultrasound-guided fine needle aspiration biopsy and consequent cytopathological examination that included immunohistochemical analysis. Herein, we discuss the presentation of a rare intranodal palisaded myofibroblastoma with emphasis on its ultrasonographic and cytopathologic features. Conclusions Intranodal palisaded myofibroblastoma should be considered in the differential diagnosis of inguinal lymphadenopathy and the diagnosis is possible with cytopathologic exam and immunohistochemical analysis using ultrasound-guided FNA biopsy, guiding the clinician to nodal excision rather than aggressive measures.
