Macrodystrophia lipomatosa is a rare congenital form of localized gigantism characterized by an increase in all mesenchymal elements, particularly fibroadipose tissue. MR imaging can be used to examine the soft tissue and detect the fibrous and fatty hypertrophy that characterizes this condition and also diagnose an associated fibrolipomatous hamartoma of the median or plantar nerve. We des...

abstract: objective: giant cell tumor of soft parts is a rare neoplasm that mainly affects adulst and the elderly and is usually located in the extremities. here we report a child with giant cell tumor of soft tissue, which is a very rare condition in childhood. clinical presentation: a 5 year old girl presented with a 5 month history of left lower extremity pain. she had developed paraplegia b...

introduction after the publication of task group number 43 dose calculation formalism by the american association of physicists in medicine (aapm), this method has been known as the most common dose calculation method in brachytherapy treatment planning. in this formalism, the water phantom is introduced as the reference dosimetry phantom, while the attenuation coefficient of the sources in the...

background:   although the majority of soft tissue masses are benign, it is important to consider malignancy in differential diagnoses. because most soft tissue sarcomas present as a painless mass, clinicians must watch for signs suggestive of malignancy, including large size, rapid growth, and site deep into the deep fascia.the purpose of this study was to determine the relative prevalence acc...

Functional regeneration of complex large-scaled defects requires both soft- and hard-tissue grafts. Moreover, bone constructs within these grafts require an extensive vascular supply for survival metabolism during the engraftment. Soft-tissue pedicles are often used to vascularize bony constructs. However, autologous tissue-harvest required fabrication remains a major procedural drawback. In cu...

Dimensional alterations of the facial soft and bone tissues following tooth extraction in the esthetic zone play an essential role to achieve successful outcomes in implant therapy. This prospective study is the first to investigate the interplay between the soft tissue dimensions and the underlying bone anatomy during an 8-wk healing period. The analysis is based on sequential 3-dimensional di...

non-hodgkin lymphoma usually presents with generalized lymphadenopathy, but it can also involve any part of the human body. lymphomatous involvement of muscles is a rare presentation and has been reported to occur in only 1.1% in non-hodgkin lymphoma. here we, present a 32 year-old iranian man with primary involvement of spleen, bone, bone marrow and muscle, mimicking soft tissue sarcoma; core ...

in this session, we will discuss 7 cases in pediatric musculoskeletal field. these cases will include different aspects of bone and msk disorders in pediatrics such as bone tumors (benign and malignant), bone involvement in metabolic and hematologic disorders, infectious diseases and soft tissue vascular lesions. during this session, we will ask some volunteered radiology residents to explain t...

This paper presents four cases of abnormal soft tissue activity in the bone scan of patients with different lesions (lung inflammatory pseudotumor, pulmonary fibrosis, pulmonary metastatic osteosarcoma and metastatic hepatic carcinoma of colon).

Current clinical experience in radiation therapy is based upon dose computations that report the absorbed dose to water, even though the patient is not made of water but of many different types of tissue. While Monte Carlo dose calculation algorithms have the potential for higher dose accuracy, they usually transport particles in and compute the absorbed dose to the patient media such as soft t...
