“…1,2 Mesenchymal tumors are uncommon accounting for only 6 to 8% of all mediastinal masses and are slightly more frequent in children. 3 They represent a heterogeneous group of benign or malignant neoplasms originating from connective tissue elements: smooth and striated muscle, lymphatic tissue, fat, and vascular tissue.…”

Angiofibrolipoma of Posterior Mediastinum with Transforaminal Extension

et al. 2016

Angiofibrolipoma is a histological variant of lipoma, which commonly occurs in subcutaneous tissues. In the present report we illustrate the case of an angiofibrolipoma of the posterior upper mediastinum in a 75-year-old man presented with progressive chest pain. Xray chest showed a homogeneous opacity vertically oriented along the right lateral aspect of thoracic vertebrae with an obtuse angle to the mediastinum. The upper extremity of the mass extended above the superior clavicle, suggestive of a posterior mediastinal lesion. Thoracic magnetic resonance imaging revealed a posterior mediastinal mass, in keeping with a nonaggressive lesion, with particular endocanalar extension and heterogeneous signal and enhancement patterns that was highly suggestive of a mixed mesenchymal tumor. The tumor was incompletely removed by right postero-lateral thoracotomy with final diagnosis of angiofibrolipoma. To the author’s knowledge, such a case of angiofibrolipoma located in the posterior mediastinum has not been previously reported in the literature.

“…On MR images, BPNTs exhibit characteristics such as a target sign, fascicular sign, the presence of a tail, or a splitfat sign that are helpful for diagnosis [1][2][3]. Among these classic MR findings, the presence of a target sign was specific for BPNT, as these signs were not present in any of the BPNT-STS cases.…”

“…Magnetic resonance (MR) imaging is the most common and useful modality for evaluating BPNTs. On MR images, most BPNTs show a well-defined fusiform mass arising along a peripheral nerve, with characteristics such as the target sign [1][2][3]. Because of their relatively distinctive clinical and MR findings, BPNTs are commonly diagnosed in clinical practice without the need for preoperative histological analysis [4].…”

“…They typically occur in asymptomatic young adults or adolescents [1], but when they achieve a large size, these tumors cause symptoms due to direct effects of the mediastinal mass, as chest discomfort, dyspnea or dysphagia, the two latter ones being consequences of tracheal or esophageal compression, respectively. Grossly, thoracic tumors are habitually fusiform or spherical and capsulated, but when they attain large sizes growing into the spinal canal and paravertebral region, they acquire a characteristic dumbbell shape [2].…”

The Transcervical Extended Access, a Feasible Approach for the Surgical Treatment of Benign Tumors of the Posterior Mediastinum?

Transcervical approach for tumors of the posterior mediastinum is traditionally thought not to be indicated. Hereby we report on a case of a patient with a huge neurogenic tumor of the posterior mediastinum which was successfully excised through a transcervical extended approach and, additionally, the variety of surgical approaches used to remove tumors of the posterior mediastinum is discussed. The new refined techniques of transcervical extended mediastinal operations, which are recently gaining popularity among surgeons, allowed for a safe dissection of the tumor, thus patient could benefit from a short painless postoperative course. The authors suggest that surgeons trained in these particular techniques should consider the choice of the transcervical extended access in selected cases of benign tumors of the posterior mediastinum.

MRI Findings of Mediastinal Neurogenic Tumors

Abstract: MRI findings reflect pathologic features of mediastinal neurogenic tumors. Integrating consideration of age and clinical findings of the patient, lesion location, and imaging findings is important in the diagnosis of mediastinal neurogenic tumors.
