A RARE COMPLICATION OF A COMMON DISEASE?

The iliopsoas muscle abscess is rare condition, with increasing recognition, that can be either primary, by hematological or lymphatic dissemination, or secondary to infections in the gastrointestinal, genitourinary tract or musculoskeletal system. Its early identification is highlighted, for an adequate therapeutic orientation, contributing to a good prognosis.

Rapidly Progressive Numbness and Weakness After Soft-Tissue Abscess

A previously healthy 45-year-old man had development of neck pain and swelling, followed 1 week later by fevers, chills, and night sweats. Cervical computed tomography showed a left-sided cervical soft-tissue abscess. The patient was treated with oral cephalexin for 10 days, without benefit. Fine-needle aspiration biopsy of the mass showed granulomatous inflammation and a heterogeneous lymphocyte population without evidence of malignancy. Meropenem and gentamicin were started. Ten days later, he had development of acute urinary retention, numbness and weakness in the lower extremities, and numbness in the upper extremities. At symptom nadir 2 days later, he required the aid of a walker to ambulate. Lhermitte sign and erectile dysfunction were also present. The patient was admitted to the hospital. Spinal cord magnetic resonance imaging showed a longitudinally extensive, nonenhancing, T2-hyperintense lesion predominantly affecting the ventral and lateral parenchyma of the cervical and thoracic spinal cord. Cerebrospinal fluid examination showed a white blood cell count of 581 cells/µL with 42% neutrophils, 35% lymphocytes, and 22% monocytes, increased protein concentration (109 mg/dL), and normal glucose concentration. A diagnosis of postinfectious idiopathic transverse myelitis was made. The patient was treated with intravenous immunoglobulin, intravenous methylprednisolone, and broad-spectrum antibiotics, with improvement of both the abscess and his neurologic symptoms. After discharge, he was able to walk unassisted. At follow-up evaluation 6 months after the initial evaluation, neurologic examination showed only mild weakness of the left iliopsoas muscle and brisk reflexes in the lower extremities. Acute transverse myelopathies are a heterogeneous group of spinal cord disorders characterized by acute or subacute signs and symptoms of spinal cord dysfunction, typically a combination of sensory, motor, and autonomic manifestations. Underlying causes include vascular, infectious, neoplastic, postirradiation, traumatic, and inherited/metabolic, and inflammatory processes.

Isolated psoas hydatidosis mimicking ovarian neoplasm

We report a unique case of hydatid cyst in iliopsoas muscle in a 65-year-old postmenopausal female. She presented with lump abdomen. On performing exploratory laparotomy, we discovered iliopsoas hydatidosis. This case reports the diagnostic dilemmas that a hydatid cyst can pose and the implications it has on management.

Two years later – changes in abdominal organs: First observations from the UK Biobank longitudinal imaging study

Longitudinal studies provide unique insights into the impact of environmental factors and lifespan issues on health and disease. Here we investigate changes in body composition in 3,088 free-living participants, part of the UK Biobank in-depth imaging study. All participants underwent neck-to-knee MRI scans at baseline and after approximately two years (re-imaging). Image-derived phenotypes for each participant were extracted using a fully-automated image processing pipeline, including volumes of several tissues and organs: liver, pancreas, spleen, kidneys, total skeletal muscle, iliopsoas muscle, visceral adipose tissue (VAT), abdominal subcutaneous adipose tissue (ASAT), as well as fat and iron content in liver, pancreas and spleen. Overall, no significant changes were observed in BMI, body weight, or waist circumference over the scanning interval, despite some large individual changes. A significant decrease in grip strength was observed, coupled to small, but statistically significant, decrease in all skeletal muscle measurements. Significant increases in VAT and intermuscular fat in the thighs were also detected in the absence of changes in BMI, waist circumference and ectopic-fat deposition. Adjusting for disease status at baseline did not have an additional impact on the changes observed. In summary, we show that even after a relatively short period of time significant changes in body composition can take place, probably reflecting the obesogenic environment currently inhabited by most of the general population in the United Kingdom.

Efficacy of iliopsoas muscle release on respiratory parameters in patients with chronic low back pain: a single blinded, two- groups, pre-test/post-test randomized controlled trial protocol

JUSTIFICATIVA E OBJETIVO: O iliopsoas e o músculo diafragma compartilham fixação comum nas vértebras L2, a contração do iliopsoas pode levar à redução da excursão do diafragma levando à dificuldade respiratória. Portanto, o presente estudo controlado fornecerá evidências sobre o efeito da liberação do músculo iliopsoas na melhoria da eficiência respiratória em pacientes com dor lombar crônica. MÉTODO / DESENHO: - Um total de trinta e quatro participantes com dor lombar crônica, com dificuldade respiratória serão recrutados com base nos critérios de seleção e serão alocados aleatoriamente em dois grupos, Grupo A (tratamento conservador + liberação miofascial iliopsoas), Grupo B (tratamento conservador + tratamento simulado). Ambos os grupos receberão a intervenção três vezes por semana durante 3 semanas. As medidas de resultado serão o Questionário de Incapacidade de Roland Morris, a Escala Numérica de Avaliação da Dor e a Capacidade de Difusão do Pulmão, pois o monóxido de carbono será usado como medidas de resultado. DISCUSSÃO: Este estudo ajudará a identificar a eficácia da liberação de iliopsoas na dor lombar e seu efeito nos parâmetros respiratórios. REGISTRO DO ENSAIO: Este ensaio foi registrado prospectivamente em cliniclatrials.gov (CTRI/2020/04/024661) em 16 de abril de 2020.

Observational Study on Lameness Recovery in 10 Dogs Affected by Iliopsoas Injury and Submitted to a Physiotherapeutic Approach

This preliminary study has investigated the outcome of physiotherapy in 10 dogs affected by a primary lesion of the iliopsoas muscle and the potential effects of sex, age, and breed on recovery. Ten dogs with primary injury of the iliopsoas muscle were retrospectively included in this study. Dogs were submitted to a rehabilitation program, characterized by a multimodal approach, including physical therapies and modalities. After recovery, patients were submitted to a further support period of rehabilitation to promote muscle strengthening and limit injury recurrence during their return to normal functional and sports activity. Border collies were highly represented. The recovery of lameness occurred after a mean of 22.6 ± 14.7 (median 18) days with a median number of five sessions. None of the examined variables affected the recovery time, except for the border collie breed, which showed a significantly faster recovery time; however, there was no difference between the breeds with regard to the number of sessions. Multimodal rehabilitation therapy may promote lameness recovery of mild-to-moderate iliopsoas lesions within 3 weeks. This preliminary study reports a clinical approach and recovery of primary iliopsoas lesions, findings that can provide clinicians with useful prognostic information for dogs involved in sports activities.
