Hyperechoic kidneys in a patient with bronchiectasis

Introduction

Hyperechoic renal cortex in a normal-sized kidney has a range of causes, some of which irreparably damage the kidney and should initiate further investigations.

Case Report

We present a 72-year-old woman with longstanding bronchiectasis, noticed to have worsening renal function. Renal tract ultrasonography showed hyperechoic normal-sized kidneys. Renal biopsy confirmed amyloidosis.

Discussion

Imaging findings in renal amyloidosis tend to be non-specific and are not always present. However, ultrasonography findings of hyperechoic cortex in normal-sized kidneys should not be ignored.

Conclusion

Renal impairment from blood chemistry in addition to hyperechoic kidneys may be the key to diagnosing secondary amyloidosis in a patient with bronchiectasis, a rare association but important to recognise.

A Case Series of Malign Hyperechoic Breast Lesions

BACKGROUND

Hyperechoic breast lesions are a rare group of breast masses in routine practice. Most of these lesions are benign. However, they rarely may be malignant. Hyperechoic lesions can be evaluated using the same criteria for malignant lesions. Clinical history, mammographic appearance, and certain sonographic features (non-circumscribed margins, irregular shape, presence of hypoechoic areas, nonparallel orientation, and association with microcalcifications can be suggestive of malignancy). In this article, hyperechoic breast lesions with malignant pathology have been presented.

METHODS

Seven cases during breast ultrasound examination were detected.

RESULTS

Four patients had invasive ductal carcinoma, 1 patient had invasive lobular carcinoma, 1 patient had high-grade ductal carcinoma in situ (DCIS), and 1 patient had lymphoma. Ultrasonography of the breast showed a heterogeneous appearance in all the patients, microcalcification in two patients, and an ambiguous contour in one patient.

CONCLUSION

Hyperechoic breast lesions should be evaluated using specific sonographic criteria to prevent misdiagnosis and identify patients who require biopsy and further examination.

Ultrasound: Basic understanding and learning the language

Ultrasound (US) use has rapidly entered the field of acute pain medicine and regional anesthesia and interventional pain medicine over the last decade, and it may even become the standard of practice. The advantages of US guidance over conventional techniques include the ability to both view the targeted structure and visualize, in real time, the distribution of the injected medication, and the capacity to control its distribution by readjusting the needle position, if needed. US guidance should plausibly improve the success rate of the procedures, their safety and speed. This article provides basic information on musculoskeletal US techniques, with an emphasis on the principles and practical aspects. We stress that for the best use of US, one should venture beyond the “pattern recognition” mode to the more advanced systematic approach and use US as a tool to visualize structures beyond the skin (sonoanatomy mode). We discuss the sonographic appearance of different tissues, introduce the reader to commonly used US-related terminology, cover basic machine “knobology” and fundamentals of US probe selection and manipulation. At the end, we discuss US-guided needle advancement. We only briefly touch on topics dealing with physics, artifacts, or sonopathology, which are available elsewhere in the medical literature.
