Purpose Orbital myositis is characterized by pain with eye movements, gaze restriction, diplopia, and enlargement of extraocular muscles on imaging. Varicella zoster virus (VZV) is an extremely rare cause of the disease in the elderly and has never been reported in a patient younger than forty-five years old such as the adolescent described herein. We present this case to raise awareness of an ...

The most frequent metastatic sites of the urothelial bladder cancers (UBCs) are bones, lungs, lymph nodes, liver, pleura, and brain. In the literature, skeletal muscle metastases from UBC have been rarely reported. We report a case of a 65-year-old male with metastatic myositis ossificans to obturator muscle 14 months after radical cystectomy performed for a muscle invasive transitional cell ca...

A 64-year-old man presented with a 2-day history of acute onset painless left ptosis. He had no other symptoms; importantly pupils were equal and reactive and eye movements were full. There was no palpable mass or swelling. He was systemically well with no headache, other focal neurological signs, or symptoms of fatigue. CT imaging showed swelling of the levator palpebrae superioris suggestive ...

A three-year-old, unspayed mongrel was presented to Small Animal Medicine unit, TVCC, River with a history of inability to open the mouth, not taking feed or water, drooling of saliva, and dullness for the past 5 days. Upon clinical observation and laboratory examination the condition was diagnosed as chronic Masticatory Muscle Myositis (MMM) and was treated with immunosuppressive doses ofcorti...

Backache with its many causes continues to present a challenge to the examining physician. Careful history taking, inspection and palpation still have an essential role, as well as the most modern imaging techniques. Although extra-pulmonary tuberculosis (TB) has shown a disproportionate increase in recent years, muscular TB is still uncommon. Necropsies of 2224 TB cases revealed only four with...

Trigger point injection is a simple procedure that is widely performed for relieving pain. Even though there are several complications of trigger point injection, myositis ossificans has not been documented as one of its complications. We treated a patient who suffered from painful limitation of elbow motion and this was caused by myositis ossificans between the insertions of brachialis and sup...

A 12-year-old boy presented with fever, lower extremity pain and weakness. Examination revealed paraparesis, thigh and calf tenderness. Labs showed high creatinine phosphokinase and Rickettsia typhi titers. This case illustrates endemic typhus should be considered in the differential diagnosis of myositis especially in areas with high prevalence of the disease. To our knowledge, this is the fir...

Here we illustrate a 74-year-old patient presenting with clinical signs of slowly progressive motor neuron disease. After electromyography demonstrated myopathic changes, a skeletal muscle biopsy was performed showing histological signs of granulomatous myositis. In extensive diagnostic workup underlying primary granulomas forming diseases were excluded and corticoid therapy was initiated, but ...

The incidence of myositis has been increasing since the advent of the epidemic of community-associated methicillin-resistant Staphylococcus aureus infection, and Panton-Valentine leukocidin has been implicated as a factor contributing to more-severe muscle injury. We report a case of severe myositis accompanying septic osteomyelitis and necrotizing fasciitis caused by a Panton-Valentine leukoci...

Phaeoacremonium parasiticum is an unusual cause of human fungal infection that was first reported in 1974. Since the initial description, only a small number of cases have been reported in the world literature. We report on the clinical and imaging findings of Phaeoacremonium parasiticum myositis in a renal transplant recipient. To our understanding, this is a first case report of Phaeoacremoni...
