Malignant lymphomas are neoplasms with diffuse proliferation of neoplastic lymphocytes and their precursor cells. Diffuse large B-cell lymphoma, which is a subtype of non-Hodgkin's lymphomas, rarely occurs in the head and neck area and is especially rare in the maxillary sinus. We report a case of a 76-year-old female patient who was referred to the oral and maxillofacial surgery office for evaluation of a dental abscess as a clinical diagnosis. Laboratory tests revealed no signs of inflammation or infection; therefore, incisional biopsy was performed. The final diagnosis was diffuse large B-cell lymphoma in the maxillary sinus. Here we describe this case with a review of relevant literature.

갈륨스캔은 여러 종류의 염증성 질환 및 종양을 발견하기 위해 사용되고 있다. 특히 림프종은 갈륨스캔에서 양성율이 비교적 높은 종양으로 알려져 있다. 하지만 기존의 평면 영상만으로는 작은 크기의 종괴나 다른 장기에 의해 가려져 있는 경우에 위음성 결과를 보일 수 있었다. 최근 단일광자 방출 전산화 단층촬영(SPCET)을 도입하여 평면영상에 비해 더 나은 공간해상력으로 많은 정보를 얻고 있다. 저자들은 비호지킨 림프종 환자 30명을 대상으로 갈륨스캔 평면영상과 SPECT 영상을 얻어 비교하였다. 병변의 부위별로 두경부, 흉부, 복부에서 평면영상의 예민도는 각각 71%, 73%, 81%였으며, SPECT 영상의 예민도는 91%, 93%, 96%였다. CT 등 방사선학적 검사소견과 임상소견을 기준으로 하였을 때 위음성율은 평면영상의 경우 24%, SPECT 6.5%였다. 장의 방사능으로 인한 섭취와 폐문부 및 침샘의 비대칭적 섭취로 인한 위양성례가 4예 있었다. 결론적으로 비호지킨 림프종의 진단 및 병기를 결정하는데 있어서 갈륨스캔이 유용하며, SPCET 영상을 얻음으로써 더 나은 해부학적 위치 및 정확한 범위를 보여 줄 수 있을 것으로 생각된다.

두경부 림프종은 두경부 림프절에 발생하는 호지킨씨병과 림프절외 림프종이 주종인 비호지킨 림프종 두종류가 있으며 이들 모두 완치율이 매우 높은 암종에 속하므로 병리학적 진단 후 정확한 병기분류를 위하여 권유되고 있는 검사들을 빠짐없이 실시하여야 된다. 조직학적 분류 및 병기가 결정된 후 내과종양의와 치료방사선의사 사이에 충분한 의 견교환을 거쳐 일차치료에 의한 근치를 유도키 위해 최선의 치료를 선택 실시함이 두경부 림프종 치료의 원칙이다.

Burkitt's lymphoma is a malignant tumor originated from B lymphocyte and a type of non-hodgkin lymphoma. It is clinically classified by endemic, sporadic and immune deficient forms. In the past, it had poor prognosis but in recent years survival rate is 50~80% treated by intensive chemotherapeutic regimens. Mostly it is a lesion of the jaws. Clinical symptoms are severe tooth mobility, displacement, gingival redness and swelling. This case is about a patient with aggressively progressing Burkitt's lymphoma of the jaws. Initial diagnosis was done in dental hospital and it has shown satisfactory outcome by prompt and appropriate treatment.

Pleural masses may be caused by various conditions, including benign and malignant neoplasms and non-neoplastic tumorlike conditions. Primary pleural neoplasms include solitary fibrous tumor, malignant mesothelioma, and primary pleural non-Hodgkin's lymphoma. Metastatic disease is the most common neoplasm of the pleura and may uncommonly occur in patients with hematologic malignancy, including lymphoma, leukemia, and multiple myeloma. Pleural effusion is usually associated with pleural malignancy. Rarely, pleural malignancy may arise from chronic empyema, and the most common cell type is non-Hodgkin's lymphoma (pyothorax-associated lymphoma). Non-neoplastic pleural masses may be observed in several benign conditions, including tuberculosis, pleural plaques caused by asbestos exposure, and pleural loose body. Herein, we present a review of benign and malignant pleural neoplasms and tumorlike conditions with illustrations of their computed tomographic images.

Primary non-Hodgkin lymphoma (NHL) of the breast is a very rare disease, and the mammographic and ultrasonographic findings of breast lymphoma are variable. There are several reports of magnetic resonance (MR) imaging findings in patients with breast lymphomas; however, few reports have described the findings observed on MR spectroscopy or the features of diffusion weighted (DW) imaging. The authors report the findings of classical MR imaging, MR spectroscopy and DW imaging of a 48-year-old woman and a 40-year-old woman with primary non-Hodgkin's lymphoma of breasts. Mammography and breast ultrasonography revealed a mass with circumscribed margin. The mass showed strong enhancement after contrast injection on MR imaging. DW imaging showed reduced diffusion and high-amplitude choline (Cho) peak at 3.22 ppm was detected by single voxel MR spectroscopy which was consistent with malignancy.

Non-Hodgkin's Lymphoma(NHL) is a malignant tumor that is derived from the lymphatic system. The most common symptoms of NHL are painless lymph node enlargement. However, we should not diagnose NHL by only fragmentary clinical symptom and radiologic finding because of the various lymphoma characters. We have treated a patient with such preoperative findings of Branchial cleft cyst. However, the pathologic diagnosis of the surgical specimen was diffuse large b-cell lymphoma.

Purpose: We assessed the absorbed dose to the tumor ($Dose_{tumor}$) by using pretreatment FDG-PET and whole-body (WB) planar images in repeated radioimmunotherapy (RIT) with $^{131}I$ rituximab for NHL. Materials and Methods: Patients with NHL (n=4) were administered a therapeutic dose of $^{131}I$ rituximab. Serial WB planar images alter RIT were acquired and overlaid to the coronal maximum intensity projection (MIP) PET image before RIT. On registered MIP PET and WB planar images, 2D-ROls were drawn on the region of tumor (n=7) and left medial thigh as background, and $Dose_{tumor}$ was calculated. The correlation between $Dose_{tumor}$ and the CT-based tumor volume change alter RIT was analyzed. The differences of $Dose_{tumor}$ and the tumor volume change according to the number of RIT were also assessed. Results: The values of absorbed dose were $397.7{\pm}646.2cGy$ ($53.0{\sim}2853.0cGy$). The values of CT-based tumor volume were $11.3{\pm}9.1\;cc$ ($2.9{\sim}34.2cc$), and the % changes of tumor volume before and alter RIT were $-29.8{\pm}44.3%$ ($-100.0%{\sim}+42.5%$), respectively. $Dose_{tumor}$ and the tumor volume change did not show the linear relationship (p>0.05). $Dose_{tumor}$ and the tumor volume change did not correlate with the number of repeated administration (p>0.05). Conclusion: We could determine the position and contour of viable tumor by MIP PET image. And, registration of PET and gamma camera images was possible to estimate the quantitative values of absorbed dose to tumor.
