A 32-year-old man was admitted to our hospital because of lumbago and an abdominal mass revealed by abdominal ultrasonography. Abdominal CT scan and MRI revealed multiple para-aortic lymph node swelling involving several arteries and veins. As there was no superficial lymph node swelling, percutaneous lymph node biopsy was performed under ultrasonographic guide. Although non-Hodgkin's lymphoma, diffuse, small cell type was suspected by light microscopic study, the monoclonality of the lymphocytes in the obtained specimen was not clear by the immunohistochemical study. Southern blot hybridization analysis of the biopsy specimen revealed the rearrangement of IgH and IgL (lambda) chain gene, indicating the existence of monoclonal proliferation of lymphoma cells. The DNA analysis appears useful for the differential diagnosis of lympho-proliferative diseases.

A 73-year-old male had severe lumbago and right inguinal lymphadenopathy. A CT scanning of his abdomen showed marked enlargement of right psoas and erector spinae muscles. The biopsies of the lymph node and the muscles revealed non-Hodgkin's lymphoma of follicular mixed type with muscle invasion. THP-COPE therapy was begun. The swelling of the muscles diminished and the lumbago resolved rapidly. It was reported that clinically prominent infiltration of of lymphoma in skeletal muscle was rarely and psoas muscle was for the most part. We have to consider that psoas muscle invasion of lymphoma cause hard to cure lumbago.

Three patients with non-Hodgkin's lymphoma involving the spinal epidural space are reported. All three patients, a 3-year-old boy (Case 1), a 63-year-old female (Case 2), and a 64-year-old male (Case 3), manifested signs and symptoms of neurological involvement before the diagnosis of malignant lymphoma was established by tissue examination. The tumors were located in the thoracic (Case 3) and thoracolumbar regions (Cases 1 and 2). The initial signs and symptoms of all cases were low back pain and progressing myelopathies. Bony abnormalities of the vertebrae, seen on both plain X-rays and computed tomographic scans, were unremarkable except for bilateral L1 pedicle erosion observed in Case 2. Total or subtotal tumor removal was followed by radiation therapy with or without chemotherapy in all cases. The primary lesion in Case 1 was a paravertebral lymphoma that had invaded the adjacent thoracolumbar epidural space through the intervertebral foramina. In Case 2, the primary lesion, documented by post-mortem examination, was a submucosal lymphoma of the stomach. In Case 3, the site of primary lesion could not be determined, although splenic and retroperitoneal nodal involvement was found at autopsy. The authors take a skeptical view of the existence of "primary" spinal epidural lymphoma, which has been reported a few times. Each of the three patients reported here presented with an epidural mass as the initial clinical manifestation of malignant lymphoma.

A 57-year-old white female, operated on for a prolapsed disc six years ago, presented with low back pain. Initially, she was thought to be suffering from the same disc problem, and was treated accordingly. However, her condition worsened. A myelogram disclosed a complete block of the subarachnoid space from levels T11 to L2. Laminectomy and decompression were performed, revealing tumor in the extradural space. Histological examination disclosed a primary, poorly differentiated lymphocytic lymphoma of the spinal cord. Both primary and metastatic non-Hodgkin's lymphoma of the spinal cord are extremely rare. Mullins et al described only five instances of cord compression in a study of 529 cases of non-Hodgkin's lymphoma. The diagnosis is generally not suspected until laminectomy.

A 69-year-old man who initially presented with lumbago developed heart failure during an MRI scan on the day of admission. A chest X-ray showed cardiomegaly and bilateral pleural effusion. Echocardiogram and computed tomography (CT) scan of the chest revealed a large tumor mass encompassing the heart with much pericardial effusion was demonstrated. The cytology of the effusion obtained by pericardiocentesis was consistent with non-Hodgkin's lymphoma, diffuse large B cell type. As CT scans of the abdomen and pelvis were negative, he was considered to have primary cardiac lymphoma. Although he responded remarkably to therapy with vincristine, cyclophosphamide and prednisolone and, he developed acute respiratory failure on the seventh month after admission. Although incidence of primary cardiac lymphoma is very low, it is necessary to investigate the mechanism of this disease in order to establish appropriate diagnostic and therapeutic approaches.

Bone marrow involvement can be found in patients with low-, intermediate-, or high-grade non-Hodgkin's lymphoma. A 40-year-old woman experienced onset of low back pain radiating into her entire right lower extremity. Plain x-rays of her right leg and computed tomography of chest, abdomen, and pelvis were unremarkable. Magnetic resonance imaging of pelvis and thighs revealed diffusely abnormal marrow signal (low T1 and high T2 weighted) in the pelvis and femora. The patient underwent (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) scan to evaluate the extent of her disease. The scan revealed diffuse scattered foci of abnormal FDG uptake in the bone/bone marrow, which was particularly intense in the axial bones. Bone marrow biopsy confirmed extensive involvement of the bone marrow with diffuse large B-cell lymphoma. This case report highlights the utility of FDG-PET in the detection of bone marrow involvement by aggressive lymphoma.

Objective: To discuss a case of leptomenigeal disease mimicking a lower lumbar disc lesion and accompanying neurological deficit.Clinical Features: A 62 year old male presented with a 3-4 day history of left low back and left posterior thigh pain. The patient had a previous history of non-specific low back pain for approximately 10-25 years, which was relieved in the past by manual therapy. He was also currently being treated by a medical oncologist with chemotherapy for low grade non-Hodgkin's lymphoma, which was considered stable.Intervention and Outcome: After a favourable initial response to therapy, the patient developed a noticeable left-sided limp. Computed tomography scanning of the lumbar spine and pelvis was then performed, which revealed a mild posterior annular bulging of the intervertebral disc at the L4/5 level. The patient was then treated with axial lumbar spine traction but on review two days later had also developed a left sided facial droop, consistent with a Bell's palsy. A subsequent magnetic resonance imaging scan of the brain and lumbar spine revealed sites of abnormal enhancement of multiple cranial nerves, the cauda equina and the vertebral bodies L1 and L5. The findings were consistent with widespread leptomeningeal disease or leptomenigeal carcinomatosis and unfortunately the patient died as a direct consequence of the disease approximately three weeks after diagnosis.Conclusion: Although relatively rare, leptomenigeal disease must considered as a differential diagnosis in a patient with a history of carcinoma who presents with low back pain and/or any neurological signs and symptoms.

We present the case of a patient presenting at the emergency department with subacute low back pain radiating to both lower limbs in whom ultrasonography and abdominal computed tomography diagnosed a retroperitoneal adenopathic mass compressing the inferior vena cava. Magnetid resonance imagin of the lumbar spine showed the retroperitoneal mass and also showed dilatation and tortuosity of the vessels of the lumbar epidural venous plexus, which was considered responsible for the radiating low back pain. Histological study defined the retroperitoneal mass as follicular non-Hodgkin's lymphoma. The dilatation of the lumbar epidural venous plexus can cause lumbar and radicular pain.

Neurolymphomatosis is a rare neurological manifestation of non-Hodgkin's lymphoma (NHL) and it may be its first and sole manifestation. Diagnosis is often difficult and nerve biopsy is generally required. However, this it is not always possible to perform or is not conclusive. We present the case of a 66-year-old woman diagnosed with giant B-cell NHL. After 6 cycles of chemotherapy, imaging and molecular biology techniques showed complete remission. At four months after treatment, the patient complained of low back pain of radicular distribution. CT and MRI imaging showed signs of lymphoproliferative activity of L5 and also lesions to thoracic nerve roots. A PET-CT was requested in order to complete the diagnosis and plan the treatment. Imaging confirmed the presence of tumor recurrence with neurolymphomatosis and also indicated lesions on the chest and abdominal level. Thus, it was decided to start a new line of chemotherapy, without performing the histological study through biopsy. This case illustrates the important role played by PET-CT imaging in neurolymphomatosis diagnosis. This technique can help the patient avoid more aggressive procedures, such as a biopsy, and can also be useful in the follow-up and assessment of the treatment response to NHL-diagnosed patients.

We present a case of 24-year-old male presented with low back pain radiating to the left lower limb, tingling numbness and weakness of 6 months duration. Magnetic resonance imaging scan with contrast reveals an extradural mass at lumbosacral region. Patient was operated with laminectomy and complete excision of the lesion was done. Patient's radicular pain relieved following the surgery and weakness also improved. Histopathology was suggestive of non-Hodgkin's lymphoma. Patient received chemotherapy which was followed by radiotherapy. Primary Non-Hodgkin's lymphoma of the lumbosacral spinal epidural tissue is an uncommon lesion. Lymphoma involves the central nervous system in 5-11% of cases either at presentation of the disease or during its course. The spinal epidural tissue is involved primarily in 0.1-3.3% of cases with spinal cord compression being the commonest presentation. Excision of the lesion followed by chemotherapy and radiotherapy is required to achieve cure.
