background: the purpose of this study is to fabricate inexpensive in-house low cost homogeneous and heterogeneous human equivalent thorax phantom and assess the dose accuracy of the treatment planning systems (tps) calculated values for different lung treatment dosimetery. it is compared with thermoluminescent dosimeter (tld) measurement. materials and methods: homogeneous and heterogeneous tho...

Three dogs (Boxer, Labrador Retriever and German Shepherd) between the age of 7-10 years were presented with the history of tumour masses on right caudo-lateral thigh, right cranial forearm and left cranial and caudal thoracic mammary gland region, respectively. Fine needle aspiration cytology of the tumour masses and the sentinel regional lymph nodes were done. Plain radiography was done to ru...

introduction spinal tumours may be classified in three groups: 1) extradural, 2) intradural extramedullary and 3) intramedullary spinal cord tumours. intradural extramedullary tumours arise from the leptomeninges or nerve roots and include schwannomas. a schwannoma is usually a firm grey-whitish tumour growing near a nerve trunk or ramus. it can be separated from the nerve without damaging neur...

Intradural spinal cord teratoma is a very rare tumour that can be associated with dysraphism. The relationship of this lesion to pregnancy is unknown and its occurrence during pregnancy in the thoracic spine has not been previously reported. We report a 19-year-old pregnant woman with spinal dysraphism, who presented with a new onset thoracic myelopathy. The MRI scan showed an intradural, extra...

Total spondylectomy has been performed previously for tumour. In 1966 a complete vertebra (the fourth lumbar) affected by a giant-cell tumour was removed in a two-stage surgical procedure : the body of the vertebra was extirpated two weeks after excision of the posterior parts (Li#{232}vre,Darcy, Pradat, Camus, B#{233}nichou, Attali and Joublin 1968). In 1968, after laminectomy, all remaining p...

A 13-year-old, female, mixed, cocker spaniel was examined for a unilateral exophthalmia and protruding mass in episcleral region of the right eye. Mode B ocular ultrasonography revealed a mass extended intraocular from anterior chamber to posterior pole without evidence of extraocular extension. A presumptive diagnosis of melanocytic tumour was made. A complete blood count and chemistry and tho...

This study describes a case of a six-year-old female crossbreed dog that had a three months history of progressive right thoracic limb lameness. Palpation revealed muscle atrophy of the scapular and humeral area and painfulness in this region. Magnetic resonance imaging was performed in T1and T2-weighted and STIR (short inversion recovery) sequences in sagittal and transverse planes. The masses...

A 26-year-old male suffering from sudden right lower abdominal pain and lumbago was referred to our hospital. Enhanced computed tomography demonstrated bilateral kidneys and spleen infarctions, and a large tumour was found occupying the aortic arch and thoracic descending aorta. We suspected that these infarctions were due to tumour embolization. The aortic arch and thoracic descending aorta we...

A 34-year-old man presented with a 5-year history of paraesthesia of the right palm and the right middle and ring fingers. This paraesthesia was exacerbated by elevation of the right arm. A tumour was palpable in the subclavicular fossa. As magnetic resonance imaging (MRI) indicated a neurogenic tumour originating from the brachial plexus, a diagnosis of thoracic outlet syndrome caused by a neu...
