A 39-year-old man, born in India but resident in the UK for 10 years, was travelling in America when he became feverish with an altered mentation. He reported a 10-day history of fever, photophobia, headache and fatigue. His medical history included hypothyroidism and migraine. He was a non-smoker, did not consume alcohol and denied a history of drug use. He was transferred to the emergency department. Laboratory investigations confirmed hyponatraemia (sodium 128 mmol/L). A chest radiograph confirmed no focal consolidation...

Nonosseous uptake in Tc-hydroxymethylene bone scintigraphy should always be evaluated for any possibility of pathological changes. We share interesting images of a 60-year-old woman initially investigated for suspected osteomyelitis of the left femur but found to have an extraosseous uptake in the right hemithorax on bone scintigraphy. Plain chest radiograph followed by contrast-enhanced CT of the thorax revealed the presence of a lung mass in the right lower lobe with no lymphadenopathy. CT-guided biopsy yielded fibrocollagenous tissue, partly lined by benign pneumocytes...

Castleman disease is a complex lymphoproliferative disease pathologically divided into two subtypes, the hyaline vascular variant (HVV) and the plasma cell variant (PCV). The HVV is the most common, is thought to represent a benign neoplasm of lymph node stromal cells, and is treated with surgical resection. It is most commonly found in the mediastinum, where it classically appears as a unicentric, avidly enhancing mass at computed tomography (CT) and magnetic resonance imaging. This appearance can mimic other avidly enhancing mediastinal masses, and location, clinical history, laboratory data, and nuclear medicine single photon emission CT (SPECT) and positron emission tomography (PET) studies can help narrow the differential diagnosis...

UNLABELLED: Splenosis is the autoimplantation of splenic tissue to ectopic sites after spleen injury. Although splenosis most commonly occurs in the abdomen, it may occur in the thorax in case of diaphragm rupture. Thoracic splenosis (TS) is often asymptomatic and is diagnosed incidentally in the course of chest examination. We describe the case of a man, with a history of thoracoabdominal trauma, undergoing routine chest radiography with the evidence of radio-opaque images close to the inferior left curvature of the cardiac shadow, which resulted to be nodules of TS at the contrast enhanced CT scan...

Ectopic anterior mediastinal parathyroid adenoma is a rare cause of Primary Hyperparathyroidism (PHPT). Imaging studies such as Technetium-99m ((99m)Tc) sestamibi parathyroid scan along with a Single Photon Emission Computerized Tomogram (SPECT), and contrast enhanced Computerized Tomogram (CT) of the neck and thorax can precisely localize the ectopic mediastinal parathyroid adenoma. We report a 40-year-old gentleman who presented with persistent pain in the right shoulder following trivial trauma. His biochemical investigations showed an elevated serum calcium of 11...

AIMS: High-energy resolution and sensitivity of novel cadmium-zinc-telluride (CZT) detector equipped SPECT systems facilitate simultaneous imaging of multiple isotopes and may enhance the detection of molecular/cellular signals. This may refine the detection of endocarditis. This study was designed to determine the feasibility and diagnostic accuracy of simultaneous imaging of inflammation with (111)In-labeled white blood cells (WBCs) and myocardial perfusion with (99m)Tc-sestamibi, for localization of WBCs relative to the valve plane in suspected endocarditis...

Renal cell carcinomas (RCCs) have a strong tendency to metastasize, and the most common sites are the lungs, bones and liver. Late recurrence is another feature of the RCC, with lesions appearing ≥10 years after surgical treatment. However, fibrosis has rarely been associated with the disease. The present study reports a case of recurrent RCC that manifested as a fibrotic mass within the thorax. A 48-year-old man presented with dyspnea that had persisted for 3 days. The patient had undergone a right radical nephrectomy for stage II clear cell carcinoma of the kidney 6 years previously...

Primary spermatic cord malignant mesothelioma is an extremely rare tumour with only 12 cases reported so far. It is an aggressive tumour with a high recurrence rate. A 45-year-old man presented with a slow growing right inguinal swelling for the past 1 year. Physical examination revealed a well-circumscribed, hard, non-reducible swelling palpable along the medial extent of the inguinal canal with no cough impulse. Fine-needle aspiration cytology suggested metastatic carcinoma. Contrast-enhanced CT of the thorax and abdomen did not reveal any primary...

HPS has been described in 9-20% of children with end-stage liver disease. We present a case of a previously, asymptomatic nine-yr-old incidentally found to have low oxygen saturation. Physical exam was remarkable for digital clubbing, splenomegaly and orthodeoxia. Laboratory evaluation revealed a low platelet count, hyperammonemia, and prolonged coagulation studies. Sonography showed evidence of splenomegaly and portal venous hypertension. High resolution CT thorax and CTA were normal. HPS was confirmed by agitated saline contrast enhanced echocardiography and Tc-99m MAA scan with evidence of intrapulmonary vascular dilatations...

Many studies have pointed out the role of (18)F-FDG PET/CT (or (18)F-FDG PET) in patients with clinical stage III or II breast cancer. (18)F-FDG PET/CT might advantageously replace other staging procedures, such as bone scanning and possibly contrast-enhanced CT of the thorax or abdomen-pelvis. We discuss the findings, locoregional or distant, that can be expected in different categories of breast cancer and their impact on prognosis and management. We also discuss the role of (18)F-FDG PET/CT in restaging and how (18)F-FDG PET/CT compares with conventional techniques in restaging for patients with suspected disease recurrence...

Desmoplastic small round cell tumor (DSRCT) presents as a rare separate clinical pathological entity, and pleural DSRCT is very rare. Following review of the English literatures it was revealed that, to date, <15 cases of primary DSRCT of the pleura have been reported worldwide. Among these, there are few computed tomography (CT) findings of pleural DSRCT which have previously been described in detail. The present study reports a pathologically proven case of pleural DSRCT, with varying contrast CT findings in a 72-year-old female, which appeared as a large (12...

Langerhans cell histiocytosis (LCH) can be associated with a variety of malignant neoplasms, the most common being malignant lymphoma, especially Hodgkin's lymphoma (HL). In this report, we describe the fine needle aspiration (FNA) cytologic features of a case with concurrent LCH and HL in a lymph node. A 20-year-old man presented with an enlarged left upper cervical lymph node. FNA smears from the swelling revealed numerous CD1a+ and S-100+ Langerhans-type cells (LCs) along with many eosinophils, neutrophils, and lymphocytes; there were also large atypical cells with enlarged nuclei having prominent nucleoli...

BACKGROUND: Extra nodal lymphoma (ENL) constitutes about 33 % of all non-Hodgkin's lymphoma. 18-28% develops in the head and neck region. A multimodality treatment with multi-agent chemotherapy (CT) and radiotherapy (RT) is considered optimum. MATERIALS AND METHODS: We retrieved the treatment charts of patients of HNENL treated in our institute from 2001-2012. The charts were reviewed and the demographic, treatment details and outcome of HNENL patients were retrieved using predesigned pro-forma...

PURPOSE: Standard cine 4D-CT (S-4DCT) is the cine CT scan of the thorax followed by image sorting with the respiratory signal recorded by the RPM. Although the feasibility of cine 4D-CT without RPM or device-less 4DCT (DL-4DCT) has been reported in a laboratory setting, the only commercial implementation of DL-4DCT was made recently by GE based on the measurements of the lung, body and air area and density. We report the initial results of this new DL-4DCT on its determination of gross tumor volume (GTV)...
