We describe a patient with nasopharyngeal lymphoma who was admitted for chemotherapy. At admission, otoscopic examination revealed a large polyp occluding the left external ear canal. The polyp was removed, and histopathologic examination showed the same tumor that was found previously in the nasopharynx. Magnetic resonance imaging showed an infiltrative process that involved the left side of the nasopharynx and extended toward the left middle and external ear. To our knowledge, this is the first case report of a direct extension of nasopharyngeal lymphoma into the middle and external ear.

Solitary Neurofibroma

Solitary neurofibroma of the heart is extremely unusual. Few reports of neurofibroma in the left ventricle have been published. In this case report, we present the results of transthoracic echocardiography, myocardial contrast echocardiography, cardiac magnetic resonance imaging, and histopathologic examination of a patient with a neurofibroma of the heart. The patient had no evidence of any other metastasis or primary tumor in other organs, which is clinically rare.

We present the case of a 37-year-old man with plasma cell granuloma affecting the middle ear and mastoid. At magnetic resonance imaging scan, the lesion appeared as a homogeneously enhancing mass of soft tissue replacing the majority of the mastoid bone and causing vascular compression. After surgical resection, microscopic examination showed predominantly plasmacytes, and histochemical studies confirmed a polyclonal origin consistent with nonneoplastic plasma cell granuloma. We believe this is the first case report of plasma cell granuloma affecting the middle ear and mastoid.

Introduction. Enchondroma protuberans is an extremely rare benign cartilaginous bone tumor. We report the first case report of enchondroma protuberans in the forearm.Presentation of Case. We report a case of enchondroma protuberans originating in the left ulnar bone of a young woman. A 20-year-old female referred to our hospital complaining of progressive sustained left forearm pain with a radiation to fourth and fifth finger. Conventional radiography revealed a well-defined eccentric osteolytic lesion in the distal diaphysis of ulna with expansion of overlying cortex (without calcification). Magnetic resonance imaging showed a well-defined ovoid intramedullary lesion, which was exophytically protruding from medial surface of left ulnar bone. Histopathology confirmed the diagnosis.Discussion. Enchondroma protuberans typically present as a well-defined intramedullary osteolytic lesion that may be accompanied by a fine matricidal calcification. The connection between the intramedullary portion and the exophytic protrusion can be seen well by magnetic resonance imaging.Conclusion. Enchondroma protuberans should be considered in the differential diagnosis of osteochondroma, enchondroma, and periosteal chondroid tumors.

Wall Tumor

A 9-year-old spayed female German shepherd mixed-breed dog presented for seizures. Magnetic resonance imaging revealed an irregularly marginated intraparenchymal cerebral mass. Microscopic examination of brain tissue collected postmortem demonstrated perivascular whorling and interwoven bundles of spindle-shaped cells. On immunohistochemistry, the tumor cells tested positive for vimentin and negative for factor VIII-related antigen, CD18, CD45, CD3, CD20, GFAP, S-100, and desmin. Immunohistochemistry results, in combination with histopathologic morphology, were suggestive of a perivascular wall tumor. To the authors’ knowledge, this is the first case report to utilize both histopathology and immunohistochemistry to describe a perivascular wall tumor in the brain of a dog.

An eight-year-old, intact male Rottweiler dog was presented due to anorexia, lethargy, ataxia and imbalance. Cerebellar and thyroid masses were identified using 0.3T magnetic resonance imaging. The <sup>18</sup>F-fluorodeoxyglucose uptakes of the masses were elevated on positron emission tomography and 7 T-magnetic resonance imaging fusion imaging. At 113 days after the initial presentation, new nodular lesions were observed in the skin, liver and spleen. Histopathology revealed multiple lesions of disseminated histiocytic sarcoma in the cerebellum, liver, spleen and skin, whereas the thyroid lesions were diagnosed as mixed medullary-follicular thyroid carcinoma. The primary site of the disseminated histiocytic sarcoma was found to be in the cerebellum. To our knowledge, this is the first case report to describe the imaging and histopathological findings of extracranial metastasis of a primary intracranial histiocytic sarcoma in a dog.

Abstract Background Management of postoperative chylothorax usually consists of nutritional regimens, pharmacological therapies such as octreotide, and surgical therapies such as ligation of thoracic duct, but a clear consensus is yet to be reached. Further, the variation of the thoracic duct makes chylothorax difficult to treat. This report describes a rare case of chylothorax with an aberrant thoracic duct that was successfully treated using focal pleurodesis through interventional radiology (IVR). Case presentation The patient was a 52-year-old man with chylothorax after a thoracoscopic oesophagectomy for oesophageal cancer. With conventional therapy, such as thoracostomy tube, octreotide or fibrogammin, a decrease in the amount of chyle was not achieved. Therefore, we performed lymphangiography and pleurodesis through IVR. The patient appeared to have an aberrant thoracic duct, as revealed by magnetic resonance imaging (MRI); however, after focal pleurodesis, the leak of chyle was diminished, and the patient was discharged 66 days after admission. Conclusions Chylothorax remains a difficult complication. Focal pleurodesis through IVR can be one of the options to treat chylothorax.
