Computed tomography and magnetic resonance imaging of an infiltrative lesion of the anterior visual pathways

Infiltrative lesions of the optic chiasm and optic nerves are uncommon. The authors report such a case and discuss the differential diagnosis, paying particular attention to imaging. In the reported case high-resolution computed tomography and magnetic resonance imaging revealed thickening of the optic chiasm and intracranial optic nerves, a pattern characteristic of an inflammatory or neoplastic process.     

CT findings of metastatic breast carcinoma involving muscle

Hematogenous metastatic disease to skeletal muscle is a very unusual occurrence and is seldom diagnosed clinically. This case report demonstrates the CT findings of metastatic breast cancer to skeletal muscle of the neck.     

Air embolism during needle placement for CT-guided radiofrequency ablation of an unresectable metastatic lung lesion

Percutaneous computed tomographic (CT)-guided radiofrequency (RF) ablation is a minimally invasive and promising procedure for unresectable lung tumors. In general, the procedure is safe and its complications are minor. A few cases of serious complications, however, have been reported. The authors report on a case of air embolism during electrode insertion into a metastatic lung tumor. The patient became unresponsive; however, he recovered 10 minutes later and the air embolism disappeared spontaneously. Although air embolism during RF ablation of a lung tumor is a rare complication, radiologists performing the percutaneous procedure should be aware of this complication and be familiar with the appropriate management.     

Imaging findings of expansile lesions of the thymus

The purpose of this article is to review the imaging findings of the different expansile lesions of the thymus. Almost 50% of all mediastinal masses are located in the anterior mediastinum. The thymus is the most common site of origin of these masses. Several kinds of lesions can arise from this gland because it derives from the three embryonic germ cell layers. Primary neoplasms of the thymus are thymoma, thymolipomas, carcinoma, carcinoid, primary germ cell tumors, and lymphoma. The latter can also involve the organ in a secondary fashion. Other lesions that cause thymic enlargement and that can be confused with neoplasia are thymic cysts and thymic hyperplasia. Even though anterior mediastinal masses are first found on conventional radiographs, computed tomography and magnetic resonance are very useful additional studies for assessing the origin and extension of these masses. The basic concepts regarding embryology, anatomy, and histology relevant for the differential diagnosis of an enlarged thymic gland are also described.     

Acute bowing fracture of the fibula in an adult.

Acute traumatic bowing of bone has only recently been recognized. Although most of these unusual fractures have been described in the pediatric forearm, bowing fractures of other juvenile long bones have also been reported. The authors describe a case of an acute bowing fracture of the fibula in a young adult.     

Hemangioendothelioma with an epithelioid phenotype arising in hemangioma of the fibula

The classification of certain vascular bone tumors that show an epithelioid cytologic appearance remains confusing, with overlap in features of epithelioid hemangioma, hemangioendothelioma and epithelioid hemangioendothelioma. Radiographs of a 27-year-old woman who presented with ankle pain showed an expanded lytic-sclerotic lesion in the distal left fibula. Magnetic resonance imaging showed an intramedullary lesion with a small lateral intracortical component. The lesion was hypo- to isointense to muscle on T1-weighted images and heterogeneously hyperintense on T2-weighted images. Initial incisional biopsy was inconclusive. Open biopsy showed hemangioendothelioma with epithelioid morphology, and the lesion was completely resected with reconstruction using a peroneal fibular rotation graft. Examination of the resected specimen showed focal hemangioendothelioma with an epithelioid phenotype arising in a hemangioma. This case illustrates the difficulty and pitfalls of making the correct diagnosis on the basis of a small biopsy specimen.Presented (case no. 17) at the 26th Closed Meeting of the International Skeletal Society, Seattle, Washington, USA, August 1999     

Renal space-occupying lesion of uncertain tumor status in metastatic testicular tumor

On the basis of a particular case of "atypical" hypernephroma the main differential diagnosis of solid renal masses are described with reference to the basis disease: testicle tumour causing metastasis. The problems of determining the dignity of the disease by methods of sonography, pyelogram and CT are pointed out as well as the differences between those characteristics of the said tumour revealed by x-ray diagnosis and the known characteristics of substantial kidney deformations as described in medical literature.
