ABSTRACT
Cardiac lipomas are exceedingly rare benign tumors of the heart. They are usually asymptomatic. Occasionally, they are found on MRI as an incidental finding. We report a case of a 68-year-old woman who presented with shortness of breath. Transoesophageal echocardiography depicted a cardiac mass lesion. The diagnosis of an intracardiac lipoma was confirmed by characterization of this mass with MRI imaging. No surgery was required since the lesion did not exert a hemodynamic effect.

OBJECTIVE: To evaluate the preoperative detection of axillary metastasis combining ultrasound (US)-guided fine needle aspiration cytology (FNAC) and liquid-based cytology (Surepath(®)) to reduce sentinel node procedures. METHODS: In total, 148 patients with clinically negative lymph nodes and no preoperative therapy were included. All patients underwent preoperative ultrasound of the axilla with FNAC if suspicious lymph nodes were found. Complete axillary lymph node dissection was performed at primary surgery when FNAC was positive. All other patients underwent a sentinel node procedure. RESULTS: US-guided FNAC of the axilla revealed metastasis in 34 (23.0%) of the 148 patients. These 34 patients were 53.1% of all patients (n = 64) with proven axillary lymph node involvement. In 66 patients (44.6%), both ultrasound and histopathology were negative. Overall sensitivity of US-guided FNAC was 50.0%, specificity 100%, positive predictive value 100% and negative predictive value 70.2%. In T1 tumours, all patients referred for sentinel node procedure were node-negative. The correlation between malignant FNAC and histopathology was 100%. US-guided liquid-based FNAC in patients with no clinically positive lymph nodes reduced the necessity for a sentinel node procedure by 23.0%. CONCLUSIONS: We advocate that US-guided fine needle aspiration (FNA) combined with liquid-based cytology of axillary lymph nodes should be included in the preoperative staging of breast cancer.

In order to avoid unnecessary therapy or treatment delay, it is important for the radiologist to be aware of the wide range of differential diagnoses for cystic lesions of the female reproductive system. This paper gives an overview of radiological findings in the variety of physiologic and pathologic cysts which may be encountered in this field.

We present a case of a 16-year-old boy with a painful swelling in the popliteal fossa, slight fever, articular and muscle pain of 3 weeks duration. Plain radiography and MR examination were performed in order to characterize the lesion. Additionally to the poorly defined mass, 2 satellite nodules were shown. Subsequent biopsy revealed a granulomatous process and 2 satellite lymphadenopathies highly suggestive of cat-scratch disease. This case shows that the differential diagnosis of a soft tissue mass of the knee should not only include tumoral processes or pseudotumoral lesions, but also granulomas from infectious or non-infectious origin. Knowledge of the patients contact with cats and the detection of skin scratches is usually the clue to the correct diagnosis.
