University Journal of Pre and Para Clinical Sciences ISSN 2455–2879 2017, Vol.3(4) SOLITARY FIBROUS TUMOR OF LUNG MIMICKING AS LUNG METASTASIS IN A KNOWN CASE OF WILMS TUMOR. SELVI Department of Pathology, MADRAS MEDICAL COLLEGE AND GOVERNMENT GENERAL HOSPITAL Abstract : Solitary fibrous tumor is the most common benign mesenchymal pleural neoplasm. It also affects mediastinum, lungs and other organs of any individual from young children to adults without sex predilection. Here we report a case of 4 years old child, a known case of treated Wilms tumor, presenting with a Solitary fibrous tumor of lung that was clinically mistaken for a lung metastasis. Ametachronous benign tumor occurring after a malignant tumor is a rare entity and whether it could bea part of any syndrome could not be established due to lack of molecular diagnostic studies. Keyword :Metachronous tumor Wilms tumor - Solitary fibrous tumor Lung. FIG 2 CT Image Axial View Mass Lesion R Lung INTRODUCTION: As the patient is a known case of Wilms tumor operated one year back, a clinical diagnosis ofmetastatic Solitary Fibrous Tumor (SFT) is a rare benign neoplasm Wilms tumor was considered. Right thoracotomy was done and arising from pleura, mediastinum and the tumor was seen as a huge pleuro pulmonary mass and the lungs and virtually at any anatomic location. The tumor is most tumor was excised. The child gave a past history of being common in patients between 20 and 70years old. Hence we operated for Wilm’s tumor – Triphasic type, one year back, report a rare case of pulmonary SFT in 4year old child, who was followed by chemo and radiotherapy for the same ailment. -
Soft Tissue Cytopathology: a Practical Approach Liron Pantanowitz, MD

A Comparison of Imaging Modalities for the Diagnosis of Osteomyelitis

Corresponding Author: Brandon J. Smith Marshall University Joan C. Edwards School of Medicine Huntington, West Virginia Email: [email protected] Abstract Osteomyelitis is an increasingly common pathology that often poses a diagnostic challenge to clinicians. Accurate and timely diagnosis is critical to preventing complications that can result in the loss of life or limb. In addition to history, physical exam, and laboratory studies, diagnostic imaging plays an essential role in the diagnostic process. This narrative review article discusses various imaging modalities employed to diagnose osteomyelitis: plain films, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, bone scintigraphy, and positron emission tomography (PET). Articles were obtained from PubMed and screened for relevance to the topic of diagnostic imaging for osteomyelitis. The authors conclude that plain films are an appropriate first step, as they may reveal osteolytic changes and can help rule out alternative pathology. MRI is often the most appropriate second study, as it is highly sensitive and can detect bone marrow changes within days of an infection. Other studies such as CT, ultrasound, and bone scintigraphy may be useful in patients who cannot undergo MRI. CT is useful for identifying necrotic bone in chronic infections. Ultrasound may be useful in children or those with sickle-cell disease. Bone scintigraphy is particularly useful for vertebral osteomyelitis. -
