How the absence of infrarenal inferior vena cava can mimic lymphoma

A 14-year-old girl was presented to the emergency department with low back pain after a spinal trauma. Unenhanced computed tomography (CT) of the spine revealed a compression vertebral fracture of the first lumbar vertebral body. Furthermore, upon examination of the CT images by soft tissue window, the physicians noticed several retroperitoneal para-aortic masses most likely attributable to lymphadenopathies (Fig.  1 – white arrow). These findings suggest, as the most plausible diagnosis, lymphoma with involvement of retroperitoneal lymph nodes.

AbstractA 51-year old presented with a 6-month history of increasing pelvic/lower back pain with nocturnal waking and episodes of anorexia and vomiting. Examination revealed right torticollis and Horner ’s syndrome, and a large abdominal mass arising from the pelvis. Magnetic resonance and positron emission tomography imaging revealed (A) a 14 cm heterogeneous enhancing mass, abutting the left kidney with standardised uptake value max = 2.9, (B) a large heterogeneous enhancing pelvic mass (C ) mesenteric adenopathy standardised uptake value max = 10.3 and (D) 6 cm right lung apex...

Conclusion: Genetic associations of diseases considerably vary across populations which necessitates health-related genotyping efforts especially for so far understudied populations. SOM portrayal represents novel promising methods in population genetic research with special strength in visualization-based comparison of SNP data. Introduction Non-communicable polygenic diseases such as cancers, neurodegeneration, cardiovascular, and metabolic disorders have become the most prevalent type worldwide and account for the majority of death events in developed and transition economy countries (Habib and Saha, 2010; Benzi...

We report a case of a 60-year-old female, suffering from non-small cell lung cancer (NSCLC), with refractory lower back pain, as expression of malignant psoas syndrome (MPS). MPS is a rare and difficult-to-treat cancer-pain syndrome, unresponsive to majority of analgesic therapy, related to psoas muscle metastasis; it is usually caused by different tumors such as uterus, ovary, bladder, prostate, colon-rectum, lymphoma, melanoma and sarcoma and represents an uncommon finding in NSCLC patients.

Abstract A 73-year-old man presented with right lower back pain and dysuria. Right hydronephrosis and a large pelvic large mass were seen on computed tomography (CT). Although his prostate-specific antigen (PSA) was 0.5 ng/mL, an irregularly enlarged, stony, hard prostate was palpable on digital rectal examination. A prostate tumor was suspected, and a transrectal prostate biopsy and right transurethral ureteral stent placement were performed. Histological and immunohistochemical studies revealed diffuse large B-cell lymphoma. Positron emission tomography-computed tomography showed abnormal uptake in the stomach, ...

Abstract The use of methotrexate (MTX) to treat rheumatoid arthritis (RA) is increasing. Recently, MTX-associated lymphoproliferative disorder (MTX-LPD) has been frequently reported as lymphoma occurring during MTX therapy. The authors report their experience with a relatively rare case of MTX-LPD presenting in the lumbar spine. The patient, a 73-year-old woman who experienced low-back pain while receiving MTX therapy for RA, was suspected of having developed MTX-LPD based on her medical history, images of the L1 vertebra, and transpedicular biopsy results. One week after discontinuing MTX, the patient's low-back ...

This article is a case report, no outcomes.Lessons:Multifocal extensive spinal TB involving the whole spine is rarely reported in the literature, which presents with atypical presentations and imaging features. It is noticeable that the possibility of TB is considered for any skip lesions involving the spine cautiously. Meanwhile, careful physical examination, trials of anti-TB treatment, and using the whole spine MRI routinely also play an important role in the diagnosis and treatment of this disease. Rationale: Skipped multifocal extensive spinal tuberculosis (TB) involving the whole spine is very rare. So far, only ...

A 28-year-old man with unremarkable past history presented with a 2-month history of low back pain and 3-day history of fever. Physical examination revealed limited range of motion while bending. His routine blood investigations showed a white blood cell count of 35 × 103/μl; platlet count of 653 × 103/μl; Hgb of 11.6 g/dl and ESR of 78 mm/1 h,CRP of 23.90 U/l, LDH of 260 U/l, ALP of 86 U/l. MRI of S-spine showed bony destruction over S1 surrounded by inflammatory process from S4 to S2 with epidural invasion. Figure 1a. The patient underwent empiric antibiotic tre...

The objective of this study was to describe the main diseases that can present with this radiologic sign, such as Hodgkin lymphoma, Paget's disease, metastatic prostate cancer, breast cancer, and osteomyelitis. It is extremely important that radiologists be aware of this finding in order to inform the requesting physician of the possible etiologies, given that it can be the initial radiologic presentation for these diseases.Resumo Pacientes com dor lombar são frequentemente atendidos em todos os níveis de saúde. O início da investigação diagnóstica, de modo geral, se d&aacut...
