 Hello everyone, myself Dr. Diwali Vittal Trimukhi, I am first year junior resident in department of radio diagnosis in BKL Malavalkar, rural medical college Pratnagiri. So today I am here to present a paper presentation in front of you. My topic is a case report of radiological manifestation of testicular tumour with metastasis. So testicular tumour represents 1% of all cancer in men. It is most common malignancy affecting young men of 20 to 34 years age group. Various risk factors includes undecended testis, testicular atrophy, client-reader syndrome, family history, history of any radiation, previous history of contralateral testicular tumour. This presentation is weight discomfort or painless mass in scrotum. Testicular tumours are divided into germ cell and non germ cell tumours. So to begin with my case, 63 year old male presented to surgery OPD with chief complaint of painless swelling in left scrotum since 6 months. Swelling was initially small which gradually increased in size, patient also has history of weight loss and loss of appetite since 6 months. Patient also has complaint of curve with expectoration. Since 6 months there is no history of pain in scrotum. Patient is a tobacco chewer since 40 years. On local examination, swelling is present in left scrotum, measuring about 10 x 6 cm. Its consistency is hard, it is non reducible and curve impulse is absent. With this clinical background, patient was subjected to radiological investigation which included chest x-ray, city abdopelvis and city chest. So this is chest x-ray PA view where we can see multiple rounded soft tissue density radio opacities of varying sizes seen scattered in both lung fills. This is city abdomen pelvis, axial and coronal section where we can see a well defined large oval shaped soft tissue density mass seen arising in left testis on post contrast. It shows heterogeneous enhancement, it shows calcipic pokai within, it also shows few hypodense areas within which are suggestive of necrosis, collection is also seen surrounding this lesion, lymph nodes are noted in pre aortic and retrocaval region, findings are likely suggestive of neoplastic etiology of testis with metastatic mediastinal lymph adenopathy. This is axial section and coronal section of high resolution city, chest and plain city chest which reveals multiple well defined heterogeneous soft tissue nodules predominantly in right lower lobe of the lung, few of them shows cavitation within, features are most likely suggestive of metastasis to lung. So biopsy was done and on histopathological examination the mass lesion shows features of seminometous germ cell tumour, based on the clinical history integrated with radiological and histological findings my diagnosis is seminoma of left testis with metastasis to lung and metastatic mediastinal lymph adenopathy, patient underwent surgical procedure which included high orchidic tommy along with chemotherapy. So testicular tumour is uncommon accounting for less than 1% of all internal organ malignancy. The commonest histology of the tumours vary with age of the affected individual. In first ticket, predominantly we can see yokes at tumour and testicular teratoma. Second decade there is predominance of coriocasinoma, in third decade predominance of embryonal cell casinoma is seen, in fourth decade there is predominance of seminoma and in more than seventh decade lymphoma, usually non-Hodgkin's lymphoma and permatocytic seminoma are common. So testicular tumour are classified into primary tumours and secondary tumours, primary tumours are further classified into germ cell tumour and non-germ cell tumour, germ cell tumour includes seminometre's germ cell tumour and non-seminometre's germ cell tumour, amongst non-seminometre's germ cell tumour it includes embryonal cell casinoma, yokes at tumour, poriocasinoma, teratoma, mixed germ cell tumour. In normed germ cell tumour it includes sertoli cell tumour, leading cell tumour, granulose cell tumour, fibromathecoma of testis and amongst the secondary tumours it includes secondary testicular lymphoma, testicular leukemia and metastasis to testis. So the spread is to the regional lymph nodes which includes aotokaval, para-aotic, para-caval, pre-aotic, pre-caval, retro-aotic and retro-caval lymph node groups and metastasis of this testicular casinoma is via lymphatic system to lung, liver, bone and other visceral sides. So on conclusion, imaging techniques which in my case included chest radiograph, city chest, city abdomen and pelvis plays a crucial role not only in diagnosis but also in staging and response assessment. Thank you.
