Skeletal muscle lymphoma is rare, comprising only a very small subset of lymphoma cases. There are characteristic imaging features which, if recognized, can prevent delay in diagnosis and treatment, particularly when not suspected clinically. Herein, we report two cases of skeletal muscle lymphoma with nearly identical imaging features; the first is an example of primary muscle lymphoma in a 17-year-old boy with back and thigh pain, and the second represents lymphoma recurrence in a 55-year-old man with HIV. Characteristic features seen on MRI were key in raising suspicion for the disease and helped prevent a delay in pathologic diagnosis.

“…Extranodal PTCL-U is a rare presentation among neoplasms. Some cases of primary skeletal muscle T-cell lymphomas have been described in the literature (8)(9)(10)(11)(12). Furthermore, in a few reported cases fluorodeoxyglucose-positron emission tomography demonstrated striking fluorodeoxyglucose uptake in multiple skeletal muscles.…”

Diffuse Skeletal Muscles Uptake of [18F] Fluorodeoxyglucose on Positron Emission Tomography in Primary Muscle Peripheral T-cell Lymphoma

A 40-year-old man presented with weakness of neck extensor muscles. Cervical magnetic resonance imaging showed high-intensity areas in muscles of the left lateral cervical region on T2-weighted images. Fluorodeoxyglucose-positron emission tomography scan demonstrated striking fluorodeoxyglucose uptake by multiple skeletal muscles of the neck, chest, and abdominal region. Muscle biopsy demonstrated peripheral Tcell lymphoma, unspecified. The diagnosis was primary skeletal muscle peripheral T-cell lymphoma. Primary skeletal muscle non-Hodgkin's lymphoma of T-cell immunophenotype is extremely rare and fluorodeoxyglucose-positron emission tomography demonstrated striking fluorodeoxyglucose uptake in multiple skeletal muscles and served as a quite useful modality for the diagnosis of this patient.

“…However, this report describes a rare case of NHL manifesting in primary skeletal muscles, which accounts for only 0.1% of all lymphomas 2. The extranodal manifestations of DLBCL generally affect the gastrointestinal tract or bone marrow and less commonly affect the skeletal muscle 1.…”

DESCRIPTIONA 78-year-old man with a history of aphasia caused by cerebral infarction came to our hospital because of persistent progressive left lower back pain for 1 week, which had radiated through the left buttock and down the left thigh.On clinical examination, he was in the right lateral decubitus position on a bed in a psoas posture with a body temperature of 36.7°C. Laboratory results revealed leucocytosis (9.71×10 9 /L), and elevated lactate dehydrogenase (415 IU/L) and creatine kinase (255 IU/L) levels.Contrast-enhanced CT of the abdomen after plain CT revealed a swollen left psoas muscle that was enhanced homogeneously (figure 1, arrows), indicating tumours in the left psoas.A pathological examination of the left psoas muscle by CT-guided needle biopsy was conducted. H&E (figure 2) and additional immunohistochemical staining results ( positive for CD20, weakly positive for CD10, negative for CD3 and terminal deoxynucleotidyl transferase, and a high MIB-1 index) were consistent with diffuse large B-cell lymphoma (DLBCL).Although the primary origin of DLBCL was unclear, the left psoas muscle was most likely compared with the swollen lymph nodes in the perirenal space and para-aorta ventral to left psoas muscle because of its considerably large size.The patient's family requested only palliative care instead of chemotherapy due to the patient's advanced age and dementia. His clinical condition gradually deteriorated, he developed multiorgan system failure and died 43 days postadmission.Non-Hodgkin lymphoma (NHL) is the most common type of lymphoma 1
