 Good morning, I am Dr. Najma I, PG resident of Pushpagiri Institute of Medical Sciences and Research Centre, Thiruvalla, Kerala. Here in my oral presentation on paper title, Cross-sectional imaging of thoracic lymphoma a pictorial assay. I will be talking about various imaging findings of lymphoma patients based on few cases which came to our institution in the recent past. So when I reviewed the literature, lymphoma accounts for 4% of all cancers. In this, NHL accounts for 90% of all lymphomas while HL constitutes the remaining 10%. The thorax is involved in 85% of all cases of HL and 45% of all cases of NHL. So distinguishing HL and NHL based on the imaging features and identifying the extra nodal involvement are crucial because this affects the staging treatment as well as the prognosis. So aim of my study is to recognize the frequency of HL and NHL in patients presented with thoracic involvement and to provide further information about the imaging features of thoracic involvement of HL and NHL. So I reviewed the CT images of 10 lymphoma patients presented primarily with thoracic involvement at our institution in the recent past. Then imaging diagnosis were compared with the pathological report. Then assess the frequency of HL and NHL and detail the spectrum of radiological manifestations of lymphoma in the thorax. So coming to my discussion, this is my first case, a 24-year-old woman who presented with fatigue and weight loss, further evaluation revealed anemia and multiple cervical lymphomes. This no history of tuberculosis, her sputum AFME was negative and X-ray short anterior migraestial mass. So we took a CEC teachers, which is showing multiple conglomerate, heterogeneously enhancing soft tissue lesions involving the anterior medial strenum. It's HPRK mass, no Hodgkin's lymphoma. In next case, a 67-year-old male presented with swelling in the right axilla and right side of his chest, X-ray short anterior medial strenum, CCD just taken, which is showing homogeneously enhancing low-bladed soft tissue lesion in the upper prevastal region of medial strenum with the necrotic areas. Then axilla CCD just images showing enhancing nodules in the anterior chest to all on the right side. As well as in the right pectoralis major with a few necrotic areas, is HPRK mass with use large B cell lymphoma. Third case, a 22-year-old male presented with cough and breathing difficulty, sputum AFME was negative, X-ray short anterior medial strenum mass. Axilla CCD just images showing heterogeneously enhancing low-bladed soft tissue lesion in only prevastal space. Here is lesion. And coronal and axilla CCD just in lung meter showing areas of interlobular septal thickening, consolidation and ground-glass capacities involving the right middle lobe as well as the anterior segment of the left upper lobe. It's HPRK mass Hodgkin's lymphoma. Next case, a 64-year-old male presented with chest wall and epicastric swelling and back pain. It was a short heterogeneous mass in the epicastrium. Axilla CCD just images showing heterogeneously enhancing low-bladed soft tissue lesion involving the anterior medial strenum, which is interding the cardia and anteriorly eroding the sephia strenum extending after the subcutaneous plane. Surgical CCD just images showing lesion extending into the epicastrium and ending the liver. Surgical CCD just in bone window showing lighted lesion in D2 vertebral body. It's HPRK mass known Hodgkin's lymphoma. Then a 29-year-old male presented with cough and breathlessness. It's just a short homogenous opacity in left upper zone. Axilla CCD just images showing heterogeneously enhancing soft tissue density lesion involving the pre-vastral space as well as the in the left upper lobe, which is causing consolidation. Then these are the axilla and coronal sections of CCD just in lung window showing bronchus cutoff sign, AF left upper lobe, bronchus. It's HPRK mass, Hodgkin's lymphoma. Sixth case, a 60-year-old male who presented with horsements of voice, dysphagia and weight loss, used to show multiple lymphoma masses in bilateral cervical lymph node stations. Axilla CCD just showing heterogeneously enhancing multiple discreet and cronchromate, mediastinal and high-layer lymph nodes. Axilla CCD just images showing evidence of right vocal cord palsy and in lung window showing lymphocytes, chiosenomatosis. It's HPRK mass, Hodgkin's lymphoma. A 22-year-old male who presented with enlarged supra-clavicle lymph nodes X-ray showing mass in the right upper zone. CCD just showing heterogeneously enhancing lobe lettuce soft tissue lesion involving the anterior medial stenum. The C image that is the third image which is taken after Kikmo under radiotherapy and showing significant escalation, it's HPRK was Hodgkin's lymphoma. Next case, a 23-year-old male who presented with breastlessness X-ray just showing anterior medial stenum mass. Axilla and coronal CCD just images showing heterogeneously enhancing lobe lettuce soft tissue lesion involving the pre-vascular space. It's HPRK mass, Hodgkin's lymphoma. Next case, a 78-year-old male female who presented with breathing difficulty for one week, Mr. Fever was present. CCD just images showing heterogeneously enhancing medial stenum lymph nodes, bilateral pleural effusion and pleural thickening on both sides. It's HPRK mass, Hodgkin's lymphoma. Last case, a 25-year-old female who presented with fever cough and breastlessness. Axilla sections of CCD just showing non-enhancing pattern of right lung field with few patchy areas of normally enhancing lung tissue and the pleural effusion. Coronal CCD just in lung tissue complete collapse of right lower lobe. It's HPRK mass, Hodgkin's lymphoma. So in 10 lymphoma patients who presented with thoracic involvement, six-way diagnostics etchel and four-way diagnostics NSL. Most of them have an overlap of imaging findings. And all of those 10 patients have medial stenum lymphoma. In addition to that, five possess pulmonary involvement, two possess pleural involvement and two possess just wall involvement. So I came to a conclusion that there is a distinct overlap between thoracic manifestations of etchel and NSL. However, the study proved that image findings are an imperative part in accurately differentiating lymphomas and recognizing the frequency of thoracic involvement. So these are my references. Thank you.
