Bright Is Not Always Better: A Pictorial Review of Hyperechoic Malignant Breast Masses.

Hyperechogenic breast lesions are a relatively rare finding at breast ultrasonography and are traditionally thought to be benign. However, hyperechogenicity on the ultrasound alone does not provide enough evidence to rule out malignancy completely. We herein reported a short series of nine cases of echogenic malignant breast lesions, which include invasive ductal carcinoma, ductal carcinoma in situ, invasive lobular carcinoma, angiosarcoma, lymphoma, and metastasis to the breast. Echogenic breast lesions should be carefully evaluated and properly categorized based on any other suspicious sonographic characteristics and must be correlated with mammographic findings and clinical history to lower the threshold for biopsy and avoid delay in diagnosis. Hyperechogenicity should not be considered as a characteristically benign feature and should not supersede the less specifically benign features of the same lesion on the other examination.

Congenital Absence of Unilateral Internal Carotid Artery with an Intracerebral Aneurysm.

The absence of the internal carotid artery (ICA) is a rare congenital anomaly. Diagnosis of this entity is important because of its association with the cerebral aneurysm and also indicated during planned carotid or transsphenoidal surgery in thromboembolic disease and in the surveillance and detection of associated cerebral aneurysms. We report a case of congenital absence of unilateral ICA with associated cerebral aneurysm of the anterior cerebral artery.

Intra-abdominal inflammatory myofibroblastic tumour (IMT) mimicking gonadal mass in a male infant with undescended testes.

Inflammatory myofibroblastic tumour (IMT) is a rare benign neoplastic tumour, originally described as an inflammatory pseudotumor. Only a single case of IMT in the spermatic cord associated with undescended testes has been reported. We present a rare case of abdominal IMT in a male infant with undescended bilateral testes. The abdominopelvic mass was suspected to be a gonadal malignancy due to empty scrotal sac but proved to be otherwise on histopathology. Mass was completely resected and orchiopexy was performed for both undescended normal-appearing testes. The patient developed a recurrent mass 2 months later involving the left spermatic cord and the left testicle. Radical surgery was performed with removal of the left testicle and spermatic cord. The patient was disease-free at 1-year follow-up.
