Docetaxel (Taxotere®)-induced cavitary change of pulmonary metastatic lesions complicated by bilateral spontaneous pneumothoraces in a patient with primary adenocarcinoma of the lung.

Pneumothorax is a complication that rarely occurs after chemotherapy for lung cancer. We report the chest computed tomography findings of a case of spontaneous pneumothorax complicating docetaxel (Taxotere®) treatment for pulmonary metastasis in a 70-year-old woman with pulmonary adenocarcinoma. The patient developed bilateral pneumothoraces, which was induced by changes in the cavitary pulmonary metastatic lesions, after systemic chemotherapy with docetaxel.

Computed tomography angiography imaging for the chimeric anterolateral thigh flap in reconstruction of full thickness buccal defect.

Background: Microvascular free flap transplantation is the current most common choice for reconstruction of difficult through-and-through buccal defect after cancer extirpation. The chimeric anterolateral thigh (ALT) flap is an ideal flap to cover this full thickness defect, but variation in the location of perforators is a major concern. Herein, we introduce computed tomographic angiography (CTA)-guided mathematical perforators mapping for chimeric ALT flap design and harvest.

Incidentally detected enhancing breast lesions on chest computed tomography.

Objective: To evaluate the nature and imaging appearance of incidental enhancing breast lesions detected on a routine contrast-enhanced chest CT.

Materials And Methods: Twenty-three patients with incidental enhancing breast lesions on contrast-enhanced chest CT were retrospectively reviewed. The breast lesions were reviewed by unenhanced and enhanced CT, and evaluated by observing the shapes, margins, enhancement patterns and backgrounds of breast lesions.

Complex cystic lesions of the breast on ultrasonography: feature analysis and BI-RADS assessment.

Purpose: To analyze the features of breast complex cystic lesions at ultrasonography (US) and to determine appropriate Breast Imaging Reporting and Data System (BI-RADS) categories and management recommendations for these lesions based on US findings with pathologic correlation.

Materials And Methods: From July 2001 to June 2007, 152 consecutive pathologically proven complex cystic lesions on US were retrospectively reviewed. All lesions at US were evaluated for size, lesion characteristics, margins, and presence of abnormal axillary nodes.

Value of sonographically guided needle sampling of cystic versus solid components in the diagnosis of complex cystic breast masses.

Background: The common practice for diagnosis of complex cystic breast masses (CCBM) may be imaging-guided aspiration or biopsy of cystic or solid components.

Purpose: To assess the diagnostic value of sonographically guided needle sampling of cystic and solid components for CCBM.

Material And Methods: Twenty patients with 20 CCBM underwent sonographically guided fine-needle aspiration biopsy (FNAB) for cystic components, followed by core needle biopsy (CNB) for residual solid components.

Atypical pulmonary metastases from a true malignant mixed tumor of the parotid gland.

A 58-year-old male patient presented with a recurrent true malignant mixed tumor of the parotid gland. Patchy pulmonary opacities were identified with a chest radiograph. Subsequently, a CT scan of the chest showed pulmonary parenchymal consolidation with amorphous calcifications.

A late complication of augmentation mammoplasty by polyacrylamide hydrogel injection: ultrasound and magnetic resonance imaging findings of huge galactocele formation in a puerperal woman with pathological correlation.

Polyacrylamide hydrogel (PAAG) was widely used for injection augmentation mammoplasty in Eastern Europe and China although uncommon in the western countries. However, the safety of this procedure remained controversial. Herein, we report a 30-year-old woman with a history of augmentation mammoplasty by PAAG injection developed galactoceles during her pregnancy.

Enhancement characteristics of ultrasmall superparamagnetic iron oxide particle within the prostate gland in patients with primary prostate cancer.

Objective: To analyze the enhancement of the prostate using ultrasmall superparamagnetic iron oxide (USPIO)-enhanced magnetic resonance imaging in patients with prostate cancer.

Methods: Sixty patients were enrolled. The signal-to-noise ratios (SNRs) of the central and peripheral zones (CZ and PZ, respectively) of the prostate were evaluated on T2- and T2*-weighted magnetic resonance imaging before and 24 hours after USPIO-enhanced MRI.

Value of automated coronal reformations from 64-section multidetector row computerized tomography in the diagnosis of urinary stone disease.

Purpose: We determined the value of automated coronal reformation using 64-detector computerized tomography for the detection of urinary stones.

Materials And Methods: A total of 72 patients underwent unenhanced 64-detector computerized tomography to diagnose urinary stones. Two radiologists independently reviewed coronal reformations and axial images at separate reading sessions.

An unusual case of thymic carcinoma with endobronchial metastases manifesting as centrilobular opacities.

We report a case of a 75-year-old man having unusual manifestation of thymic carcinoma associated with endobronchial metastases. To our knowledge, endobronchial metastases secondary to thymic carcinoma has not been reported in the literature. On high-resolution computed tomograms, the tree-in-bud centrilobular opacities caused by metastatic cells accumulating within the small bronchioles is indistinguishable from that caused by inflammatory process.

Assessment of CT urography in the diagnosis of urinary tract abnormalities.

Background: To evaluate the accuracy of helical computerized tomography urography (CTU) in diagnosing urinary tract disease.

Methods: We collected 102 patients who underwent CTU from March 2001 to September 2002. The clinical symptoms of these patients included: flank pain or hematuria, which were clinically suggestive of urinary system disorders.

Diagnostic value of unenhanced computerized tomography urography in the evaluation of acute renal colic.

This study prospectively evaluated the diagnostic value of unenhanced computerized tomography (CT) urography in patients with acute renal colic. Fifty-nine patients with clinical manifestations of acute renal colic underwent unenhanced helical CT to evaluate urinary tract abnormalities. Reformatted three-dimensional CT urography was performed in all patients.

Malignant renal epithelioid angiomyolipoma with aggressive behavior and distant metastasis.

Angiomyolipoma (AML) is a common renal tumor and mostly benign in entity. Malignant AML is extremely rare and most of them are found to be epithelioid AML histopathologically. We report the imaging features of a malignant epithelioid AML in a 58-year-old patient with liver and nodal metastases, and review the literatures.

Tumor and tumor-like lesions of duodenum: CT and barium imaging features.

Neoplasms of the duodenum, either primary or secondary, are uncommon. However, imaging diagnosis for presurgical evaluation is extremely important due to complex regional anatomy. Computed tomography (CT) and barium-based double contrast examination (UGI series) are most frequently employed to evaluate the tumor invasion and intraluminal mucosal pattern.

A rare giant intracranial osteochondroma.

Osteochondroma is the most common benign bone tumor. However, intracranial osteochondroma is very rare, which usually arises from the skull base. Origination from the dura and falx occurs only in sporadical cases.
