Hemipelvectomia interna: relato de oito casos

Abstract

The authors declare that there was no conflict of interest in conducting this work ABSTRACTInternal hemipelvectomy is a surgical procedure adequate for treatment of certain tumors of the pelvic girdle. Being a lower limb-preserving approach, it is a therapeutic alternative to the classical interilioabdominal amputation and hip joint disarticulation. According to Enneking`s classification, there are four types of internal hemipelvectomies, although the association of different types of resection in the same procedure is feasible if necesary. This surgical approach should be correctly indicated to positively affect the patient`s morbidity, mortality and quality of life. We report eight cases of internal hemipelvectomy in patients diagnosed with tumors of the pelvic girdle. We also discuss the neoadjuvant and adjuvant treatments used, along with their follow-up.

Hemangioma intraósseo difuso agressivo: Relato de caso

“…When reported, it usually presents in a region, such as several vertebral bodies, but it is not usually distributed in different places of the body. 1,4 The most common locations of hemangiomas are the skull and axial skeleton. In the spine, thoracic localization is more common in the middle and lower regions, followed by the lumbar region, occurring more rarely in the cervical region.…”

“…Some of these lesions are malformations, while others, due to the growth with neoplasia characteristics, are considered true benign tumors. 1 The most common locations of hemangiomas are the skull, where they can produce the classical image in "sun rays", and the axial skeleton, usually without any clinical symptomatology. 1 Most often, hemangiomas do not require treatment, but rather periodic follow-up.…”

“…The mean age of the patients is 40 years old, being more frequent in women, in the proportion of 3:2. 1,2 In plain radiography, hemangiomas are characterized by parallel vertical trabeculates in vertebral bodies. Computed tomography (CT) reveals the presence of thick trabeculae and radiotransparent areas, and magnetic resonance imaging (MRI) is highly sensitive and specific, presenting hyperintense signs on T1 and T2.…”

“…Computed tomography (CT) reveals the presence of thick trabeculae and radiotransparent areas, and magnetic resonance imaging (MRI) is highly sensitive and specific, presenting hyperintense signs on T1 and T2. 1 We describe a rare case of aggressive hemangiomatosis in a young patient in order to demonstrate its clinical presentation, imaging, as well as the evolution of the patient with the treatment performed. Finally, we alert to the diagnosis of hemangioma as a differential diagnosis in multiple and also aggressive bone lesions.…”
