We report a case of a patient of 58 years old who suffered from a left apical opacity occurring in a context of deterioration in general health. Subsequent clinical developments were dominated by the ophthalmic disease and a frontal syndrome. The radiological work-up showed tumoral lesions which had developed from the first rib, from the structures at the base of the cranium and the frontal area and were associated with multiple lacunae of the cranial vault. There was evidence of hyperproteinaemia, and an IgG gamma monoclonal gammopathy, a significant medullary plasmocytosis with morphological anomalies of the plasmocytes leading to a diagnosis of myeloma with a plasmocytoma of the rib and the retro-orbital area. Thoracic disease associated with this pathology is common but mainly present as osteolytic lesions. The occurrence of intrathoracic plasma cell tumours is rarer as are orbital manifestations. In spite of treatment which can frequently lead to an objective response, the prognosis of this disorder remains gloomy.

A 42-year-old man presented with a one-month history of upper back pain and a two-week history of progressive spastic paraparesis. Thoracic spinal MRI showed an epidural mass with spinal cord compression at T6-8 but no bony involvement. The patient underwent T6-8 laminectomy for decompression. Lumbosacral MRI and CT scans revealed bony abnormalities on the sacrum and left posterior iliac bone. Immunohistochemical studies confirmed the diagnosis of multiple myeloma (MM). Thus, this patient suffered from extraosseous MM without adjacent bony involvement or distant skeletal involvement.

An 11-year-old, castrated male, Domestic Medium Hair cat was presented to the University of Florida Small Animal Hospital with a 2-week history of upper respiratory infection and increased serum globulins, as reported by the referring veterinarian. Physical examination was unremarkable other than melanosis of the left iris, with no evidence of ocular, nasal, or respiratory disease. Laboratory abnormalities included moderate nonregenerative anemia, mild leukopenia, mild hyperfibrinogenemia, severe hyperglobulinemia, mild hypoalbuminemia, and hypocholesterolemia. Abdominal radiographs and ultrasonographic examination revealed mild splenomegaly with no other abnormalities. Thoracic radiographs revealed no abnormalities. Cytologic evaluation of fine-needle aspirates from the spleen, liver, and bone marrow revealed numerous plasma cells and many vacuolated macrophages exhibiting marked phagocytosis of mature erythrocytes and platelets, occasionally metarubricytes and leukocytes, and rarely plasma cells. The cytologic interpretation was multiple myeloma and associated hemophagocytic syndrome (HPS). Serum protein electrophoresis revealed a monoclonal gammopathy, providing further evidence for a multiple myeloma. To the authors' knowledge, this is the first report of HPS secondary to neoplasia in a cat.

Multiple myeloma (MM) is a malignant proliferation of a single clone of plasma cells and an excess of monoclonal immunoglobulin production. It is rarely associated with cutaneous and pleural involvement. We report a new case of a 62-year-old woman with a history of a symptomatic MM. Three months after chemotherapy initiation, she presented with subcutaneous nodules. Ultrasound-guided needle biopsy confirmed the diagnosis of cutaneous plasmacytomas. She underwent local radiation therapy leading to complete regression of subcutaneous nodules. One month later, she developed dyspnoea. Thoracic CT scan showed pleural thickening associated with pleural effusion. Pleural biopsy confirmed the diagnosis of pleural plasmacytoma. Chemotherapy including vincristine, doxorubicin and dexamethasone was administered. Cutaneous involvement and pleural effusion accompanying MM are uncommon. They are associated with poor prognosis.

Interpretation of thoracic spine radiographs is difficult because they cannot clearly depict the vertebrae due to overlap with soft tissues. This study aimed to evaluate whether thoracic spine radiographs obtained using the energy subtraction method could improve the accuracy of a diagnosis of thoracic osteolytic lesions. The authors analyzed 300 thoracic vertebrae from 25 patients with multiple myeloma who underwent thoracic spine radiography. All patients underwent thoracic spine radiography with 2 views. Two sets of images were prepared: computed radiography images (CR images) acquired using conventional processing parameters; and processed images for specifically visualizing bone, using the energy subtraction method (ES images). The CR images (CR group) and paired CR and ES images (CR+ES group) were interpreted in parallel by 5 orthopedic surgeons. The presence of osteolytic lesions was evaluated for each of the 12 thoracic vertebrae, and the sensitivity and specificity of the method were compared with computed tomography (CT), which is considered the gold standard. Subgroup analysis was also performed based on location. Osteolytic lesions were found on CT in 28 (9.3%) vertebrae of 12 patients. The overall sensitivities and specificities of the CR and CR+ES groups were 17.2% and 54.3%, respectively, and 95.6% and 98.0%, respectively, with statistically significant differences. Subgroup analysis showed particular improvement in the sensitivity for the CR+ES group in the middle thoracic spine compared with that at other locations. Thoracic spine radiographs generated using this method may improve the accuracy of diagnosis of thoracic osteolytic lesions. [Orthopedics. 2021;44(x):xx-xx.].
