Polyarteritis nodosa (PAN) is a medium vessel vasculitis affecting systemic organs. Muscle involvement of PAN usually lacks elevation of creatinine kinase (CK). We herein report a case of PAN with rhabdomyolysis. A 71-year-old man was hospitalized because of muscle weakness of the lower limbs that persisted for 1 month. On a physical examination, rapidly progressive lower proximal muscle weakness and bilateral drop foot were observed. His blood test showed an elevation in the C-reactive protein (CRP) (19.5 mg/dL) and CK (13,435 IU/L) levels and negativity for anti-neutrophilic cytoplasmic antibody (ANCA)...

Ruptures of the tendon of the tibialis anterior muscle tend to occur in the context of degenerative impairments. This mainly affects the distal avascular portion of the tendon. Owing to the good compensation through the extensor hallucis longus and extensor digitorum muscles, diagnosis is often delayed. In addition to the clinical examination, magnetic resonance inaging (MRI) diagnostics are of particular importance, although damage or rupture of the tendon can also be demonstrated sonographically. Therapeutic measures include conservative or operative measures, depending on the clinical symptoms...

REVIEW
Leah E Waldman, Stephen C Scharf
Radionuclide bone scanning has been used routinely in the evaluation of bone pathology for decades. The greatest strength of the procedure is its extreme sensitivity for bone metabolism, allowing it to distinguish between active and inactive bony abnormalities. The downside of this reliance on abnormal bone turnover is the relative lack of anatomical detail compared with ever-improving CT and MRI technology. Fusion imaging using SPECT/CT (SCT), PET/CT, and PET/MRI offers an opportunity to combine the sensitivity of nuclear medicine examinations with the anatomical detail of CT and MRI...

INTRODUCTION: Hip abductor tendon (HAT) tearing is commonly implicated in greater trochanteric pain syndrome. Surgical studies are often reported in small cohorts and with limited information on functional improvement. This study reports the clinical and functional outcomes after HAT repair. METHODS: 112 patients with symptomatic HAT tears, diagnosed via magnetic resonance imaging, underwent open bursectomy, V-Y lengthening of the iliotibial band, debridement of the diseased tendon, decortication of the trochanteric foot-plate and reattachment of the tendon with suture anchors, augmented with a LARS ligament through a trans-osseous tunnel...

Diabetic foot is one of the most debilitating complications of diabetes and may lead to plantar ulcers. In the last decade, gait analysis, musculoskeletal modelling (MSM) and finite element modelling (FEM) have shown their ability to contribute to diabetic foot prevention and suggested that the origin of the plantar ulcers is in deeper tissue layers rather than on the plantar surface. Hence the aim of the current work is to develop a methodology that improves FEM-derived foot internal stresses prediction, for diabetic foot prevention applications...

Lipoma is rare in the planter aspect of the toes, and only few cases of massive lipoma have been reported in this site. The differential diagnosis of masses in the foot and toes is wide, and clinical diagnosis may be challenging. Access to magnetic resonance imaging, a standard diagnostic investigation for such soft tissue masses of the foot and toes, may be limited in some practice, requiring a reliance on clinical signs. We report a solitary massive lipoma in the planter aspect of the right great toe that appeared as two masses and with modification of typical clinical signs of lipoma...

Objectives: The use of hand and foot MRI in the diagnostic process of RA has been advocated. Recent studies showed that MRI is helpful in predicting progression from clinically suspect arthralgia (CSA) to clinical arthritis, and from undifferentiated arthritis (UA) to RA. Symptom-free persons can also show inflammation on MRI. This study aimed to evaluate if MRI findings in symptom-free volunteers are relevant when defining a positive MRI. Methods: Two hundred and twenty-five CSA patients and two hundred and one UA patients underwent MRI of MCP, wrist and MTP joints at baseline and were followed for 1 year on progression to arthritis and RA, respectively, as reported previously...

Acute bilateral foot drop is a rare clinical presentation. A 77-year-old male presented with acute bilateral weakness of the foot and ankle dorsiflexion. Magnetic resonance imaging of the lumbar spine revealed ligamentum flavum hypertrophy as well as a mass lesion that appeared hyperintense on T1-weighted images and hypointense on T2-weighted images. Emergent decompressive laminectomy and hemorrhagic synovial cyst excision were performed. Histopathological examination of the tissue revealed a synovial cyst with hemorrhage...

BACKGROUND AND OBJECTIVE: Nowadays, pulsed radiofrequency (PRF) is being used to control several types of musculoskeletal pain. Herein, we report a successful application of ultrasound (US)-guided PRF for a patient with refractory sciatic neuropathic pain. CASE REPORT: We applied US-guided PRF to a 50-year-old man, suffering from refractory neuropathic pain on the left foot following sciatic neuropathy for a period of approximately 6 months. We performed PRF on the level of piriformis muscle because the lesion of the sciatic nerve was presented digitally from the level of piriformis muscle on the magnetic resonance images...

INTRODUCTION: Deep brain stimulation (DBS) is an effective treatment for multiple movement disorders and shows substantial promise for the treatment of some neuropsychiatric and other disorders of brain neurocircuitry. Optimal neuroanatomical lead position is a critical determinant of clinical outcomes in DBS surgery. Lead migration, defined as an unintended post-operative displacement of the DBS lead, has been previously reported. Despite several reports, however, there have been no systematic investigations of this issue...

A four-channel Tic-Tac-Toe (TTT) transmit RF coil was designed and constructed for foot and ankle imaging at 7T MRI. Numerical simulations using an in-house developed FDTD package and experimental analyses using a homogenous phantom show an excellent agreement in terms of B1(+) field distribution and s-parameters. Simulations performed on an anatomically detailed human lower leg model demonstrated an B1(+) field distribution with a coefficient of variation (CV) of 23.9%/15.6%/28.8% and average B1(+) of 0.33μT/0...

BACKGROUND/AIMS: Fabry disease (FD), an X-linked lysosomal storage disorder, leads to accumulation of globotriaosylceramide. Screening in dialysis patients may identify genetic variants of unknown clinical significance. We aimed to characterize the pathogenicity of a novel GLA gene mutation identified during hemodialysis screening and the histologic findings of early Fabry nephropathy. METHODS: One out of 108 male hemodialysis patients screened for FD presented low α-galactosidase A activity...

The foot is rarely the focus of osteoid osteoma, and only a few of those cases are related to the fifth metatarsal. The present case demonstrates that atypical symptoms with suspicious findings on plain radiographs that are not associated with trauma must be analyzed carefully to determine the nature of the lesion and perform the precise treatment to obtain and sustain the cure. A 29-year-old man presented to the outpatient clinic with a 2-year history of chronic pain in the lateral aspect of his left forefoot...

Giant-cell tumor of the tendon sheath (GCT-TS) is an uncommon occurrence for a foot and ankle surgeon. However, there is a need to recognize the symptoms of typical and atypical presentations of this pathology. These benign neoplasms are recognized clinically as a soft-tissue mass that is usually painless and palpable. The foot and ankle account for only 3% to 5% of all GCT-TS in the body, with most being located in the hand. Giant cell tumor in the tendon sheath occurring in the foot and ankle is usually encountered on the lateral ankle and dorsum of the foot, occupying the extensor tendons...
