the aim of this study was to assess the value of 99mtc-hexakis-2-methoxyisobutylisonitrile (mibi) scintigraphy in patients with clinical and radiologic features of primary or metastatic musculoskeletal tumors. methods: the scintigraphic findings for 84 patients were compared with the surgical and histologic findings. each patient underwent three-phase bone scan with 99mtc-methylene diphosphonat...

We report a case of sporadic isolated hemangioblastoma arising from the retroperitoneum and provide a review of the scarce literature regarding this very rare tumor. Furthermore, we thoroughly describe the pathologic features and the broad differential diagnosis that should always be included in the study of any retroperitoneal soft tissue mass to arrive at the final diagnosis.

Chronic obstructive pulmonary disease is defined as a preventable and treatable disease state characterized by airflow limitation that is not fully reversible. This review will discuss the relevant anatomy of the secondary pulmonary lobule, the subtypes of emphysema, and their imaging appearances and corresponding pathologic findings.

Chronic hepatitis is a frequent pathologic condition encountered in both dogs and humans; however, in the latter etiologic factors are usually searched and found that allow targeted therapeutic approaches, whereas in dogs this is less frequent. This review will take into consideration chronic hepatitis in dogs, and discuss differences and similarities between the two species with respect to thi...

IN PERIARTERITIS NODOSA the cardiae lesions contribute greatly to the manifestations of the disease and often are directly responsible for the death of the patient. The purpose of this study is to doeument the cardiac lesions of periarteritis nodosa, to review the clinical manifestations of this condition referable to the heart, and to relate the clinical manifestations to the pathologic lesions.

Objective: The authors review anatomical, clinical characteristics and prevalence of thyroid microcarcinoma. Diagnostic procedures and risk factors of aggressiveness at diagnosis and during follow-up are also reviewed. The possible clinical, pathologic and therapeutic risk factors are scrutinized by meta-analysis. Treatment procedures by different authors and guidelines suggested by societies a...

Traumatic neuroma is a well-recognized complication of lower extremity amputation, yet has also been noted to occur elsewhere. We report a clinical case and English-language literature review of traumatic rectal neuroma, a well-known pathologic entity not previously reported in this anatomic location.

Leiomyosarcoma typically occurs within the uterus, gastrointestinal tract, and mesentery. Primary skeletal leiomyosarcoma is exceedingly rare. The radiographic appearance is similar to that of other aggressive sarcomas of the bone. Definitive diagnosis is achieved through biopsy or excision and pathologic review.

A considerable number of people harbor intracranial aneurysms (IA), which is a focal or segmental disease the arterial wall. The pathophysiologic mechanisms IAs formation, growth, and rupture are complex. mechanism also differs with respect to type aneurysm. In broad aspects, may be considered vessel addition classic risk factors genetic/environmental conditions, altered structural pathologic e...
