Intrathoracic caudate lobe of the liver:A case report and literature review

引用

World Journal of Gastroenterology 2014年第17期20卷 5147-5152页

作者： Ying-Yi Chen tsai-wang huang Hung Chang Hsian-He Hsu Shih-Chun Lee Division of Thoracic Surgery Department of Surgery Department of Radiology Tri-Service General HospitalNational Defense Medical Center

Heterotopic supradiaphragmatic livers are rare. A total of 23 cases of primary supradiaphragmatic livers have been reported in the literature. The clinical presentations of heterotopic supradiaphragmatic liver are variable. The simultaneous detection of intrathoracic accessory liver and pulmonary sequestration is extremely rare, and only one case has previously been reported. It is difficult to make a correct diagnosis preoperatively. We presented a 53-year-old woman with complaints of an intermittent, productive cough and dyspnea for two months that was refractory to medical treatment. She had no previous history of trauma or surgery. A chest radiograph only showed a widening of the mediastinum. Contrast-enhanced computed tomography of the chest revealed a well-circumscribed homogenous soft-tissue mass, approximately 4.35 cm × 2.5 cm × 6.14 cm in size, protruding through the right diaphragmatic crura to the right pleural cavity, attached to the inferior vena cava, esophagus and liver. There was no conclusive diagnosis before surgery. After the operation, we discovered that this patient was the first case of a supradiaphragmatic heterotopic liver, which passed through the inferior vena cava foramen and was coincidentally combined with an intralobar pulmonary sequestration that was found intraoperatively. We discussed its successful management with surgical resection via a thoracic approach and reviewed the published literature.

Three-dimensional image simulation of primary diaphragmatic hemangioma: A case report

BACKGROUND Fewer than 200 cases of diaphragmatic tumors have been reported in the past century. Diaphragmatic hemangiomas are extremely rare. Only nine cases have been reported in English literature to date. We report a case of cavernous hemangioma arising from the diaphragm. Pre-operative three-dimensional(3D)simulation and minimal invasive thoracoscopic excision were performed successfully, and we describe the radiologic findings and the surgical procedure in the following *** SUMMARY A 40-year-old man was referred for further examination of a mass over the right basal lung without specific symptoms. Contrast-enhanced computed tomography revealed a poorly-enhanced lesion in the right basal lung, abutting to the diaphragm, measuring 3.1 cm × 1.5 cm in size. The mediastinum showed a clear appearance without evidence of abnormal mass or lymphadenopathy. A preoperative 3D image was reconstructed, which revealed a diaphragmatic lesion. Video-assisted thoracic surgery was performed, and a red papillary tumor was found, originating from the right diaphragm. The tumor was resected, and the pathological diagnosis was cavernous *** In this rare case of diaphragmatic hemangioma, 3D image simulation was helpful for the preoperative evaluation and surgical decision making.

Sub-Nyquist sampling-based wideband spectrum sensing:a compressed power spectrum estimation approach

In this paper,we introduce a sub-Nyquist sampling-based receiver architecture and method for wideband spectrum *** of recovering the original wideband analog signal,the proposed method aims to directly reconstruct the power spectrum of the wideband analog signal from sub-Nyquist *** that power spectrum alone is sufficient for wideband spectrum *** only the covariance matrix of the wideband signal is needed,the proposed method,unlike compressed sensing-based methods,does not need to impose any sparsity requirement on the frequency *** proposed method is based on a multi-coset sampling *** exploiting the inherent sampling structure,a fast compressed power spectrum estimation method whose primary computational task consists of fast Fourier transform(FFT)is *** results are presented to show the effectiveness of the proposed method.
