Imaging of pseudoangiomatous stromal hyperplasia of the breast

Rare benign breast lesion that commonly affects premenopausal women. It is a myofibroblastsproliferation around optically empty slots giving a false appearance of vascular network of its name [pseudoangiomatous] hyperplasia where there is absolutely no vascular injury. It appears as a single mobile breast nodule, firm, usually unilateral and as a net opacity with regular contours and without microcalcifications.]V1. We present two lesions that were classified as malignant in the initial control by mammography, wich led to a needle biopsy.But no any histological sign of malignancy was shown. The diagnosis requires ultrasound-guided percutaneousbiopsy or stereotacticbiopsy for histological study. The false appearance of vascular network can mimic on a first reading a low-grade angiosarcoma. Then, immunohistochemistryis needed to demonstratemyofibroblastic origin. The resection must be complete with a long-term surveillance because of the risk of recurrence of up to 20% of cases when resection is not total. The diagnostic alternative is currently provided by the ultrasound guided percutaneous biopsy or stereotactic biopsy, which determines the nature of the lesion and rules out malignancy, such as angiosarcoma, in order to avoid unnecessary surgical biopsies

Papillary carcinoma breast and fibrocystic dystrophy

The intracystic breast cancer is rare, it may present a misleading cystic appearance. Ultrasound shows an endocystic bud. Histology often found papillary carcinoma. Patient of 27 years followed for fibrocystic dystrophy. Breast ultrasound showed an heterogeneous cystic biloculee. The echographic control is increased the size of the cyst. Surgical excision shows that this is an intracystic papillary carcinoma in situ. MRI done at postoperative inflammatory banks, the recovery of post-operative banks reveals multiple microscopic foci of carcinoma in situ high grade. Mastectomy was performed. The intracystic ductal carcinoma is a rare malignant tumor of the ductal elderly woman. It is characterized by slow growth, with a good prognosis. Often discovered during a breast swelling recently enlarged. A mammogram shows a well-circumscribed oval mass, or sometimes indistinct in places. Breast ultrasound can reveal any complex cysts with a solid component, hyperechoic pendant to the inner wall of the cyst. Eliminates the doppler diagnostic reshaped heavy cyst content and confirms the tissue character by the presence of a central vascular pedicle. Ultrasound is the best test to distinguish between solid and liquid formations breast with mammographic appearance is close to intracystic carcinomas as medullary cancer and breast cysts. The best distinguishing criteria I seem to be: a large size of the intracystic vegetation, heterogeneous echogenicity and irregular edges of the intracystic mass. Some carcinoma in situ high grade can be mistaken for cystic lesions overhaul. The ultrasound meticulous analysis of the lesion i and its edges of its outline and its vascularization moving towards malignancy. Nevertheless, surgical resection is needed in doubt before any atypical cystic lesion

[ imaging findings of the carotid chemodectom]

The carotid body tumor, which arises from its chief cells [glomus type 1], is the most common paraganglioma of the head and neck [up to 50%]. The following case report is particularly useful for daily practice; the patient has surgical history of tiroid neoplasm which requires a thorough diagnosis, in order to determine an accurate follow-up. This tumor is in most cases clinically silent and is detected incidentally at imaging study during evaluation of patients with unrelated symptoms such as painless, slowly growing lateral neck mass, dysphagia, sleep apnea, and paresia or atrophy of the tongue. According to its appearance, precise non-invasive imaging techniques may allow the radiologist to reach the correct diagnosis and treatment
