Cervical myositis ossificans traumatica : a rare location. An unusual case of myositis ossificans traumatica lesion located in the paraspinal region is reported. Despite the contiguity of the lesion with the cervical vertebrae and ominous appearance of the biopsy material, the history of antecedent trauma and computed tomography findings allowed preoperative accurate diagnosis.

To our knowledge, myositis ossificans traumatica located in the cervical paraspinal region is very rare. Baysal, T. With 4 figs. A yr-old sexually intact female vampire bat Desmodus rotundus was diagnosed with myositis ossificans traumatica of the abdominal wall.

The bat presented with a large ulcerated firm mass along the abdomen. Radiographs and cytology were performed, followed by surgical exploration. The mass was determined to be nonresectable and the bat was euthanized. Histopathology showed severe necrotizing, degenerative, and pyogranulomatous myositis with osseous and cartilaginous metaplasia, fibrosis, and ulceration, which were consistent with myositis ossificans traumatica.

Myositis ossificans traumatica is commonly associated with previous trauma to skeletal muscle. Two years prior, this bat had an emergency Caesarian section at this site, which was postulated to elicit a marked tissue response leading to this condition.

Myositis ossificans traumatica is infrequently reported in humans, dogs, cats, pigs, and horses. To the author's knowledge, this is the first report of this condition in a bat. Myositis ossificans traumatica is an unusual complication following a muscle contusion injury. A significantly large myositic mass causing ankylosis of the elbow is even rarer. We report a year-old boy who presented with a month history of a fixed elbow with no movement and a palpable bony mass in the anterior aspect of the elbow.

He had sustained significant trauma to the affected limb 1 month prior to onset of symptoms, which was managed by native massage and bandaging for 4 weeks. Myositis ossificans traumatica causing ankylosis of the elbow.

The clinicoradiological diagnosis was suggestive of myositis ossificans, and the myositic mass was completely excised. Histopathology revealed lamellar bone. The 2-year follow-up showed full function of the affected limb and no signs of recurrence. We report this case of clinical interest due to the unusually large myositic mass. The aim of this study was to evaluate the surgical outcomes of a modified approach in the management of thick submacular hemorrhage in patients with wet age-related macular degeneration.

This was a retrospective study. A retrospective chart review was performed on 10 eyes of 10 patients with submacular hemorrhage secondary to wet age-related macular degeneration treated with gauge pars plana vitrectomy, followed by submacular injection of recombinant tissue plasminogen activator Patients were evaluated for displacement of hemorrhage, preoperative and postoperative best-corrected visual acuity, occurrence of intraoperative and postoperative complications, and recurrence of hemorrhage.

All patients were followed up for 6 months. Displacement of the submacular bleed was achieved in all cases. Improvement of best-corrected visual acuity was seen in 8 of 10 patients. This modified technique aids in the effective displacement of thick submacular hemorrhage with simultaneous treatment of the underlying choroidal neovascular membrane, which halts the disease progression resulting in significant improvement of visual acuity.

A fatal case of metastatic squamous cell carcinoma in a patient with myositis ossificans traumatica. Myositis ossificans traumatica is a rare disease associated with chronic wounds and fistulae. Chronic ulcers, fistulae and wounds can transform into squamous cell carcinoma, the so-called Marjolin's ulcer.

We describe a rapid, progressive and fulminant course of a metastatic squamous cell carcinoma. Persistent submacular fluid diagnosed with Optical Coherence Tomography after successful scleral buckle surgery for macula-off retinal detachment.

The objective of our study was to analyze the presence of persistent submacular fluid after apparently successful scleral buckle surgery for macula-off retinal detachment, using Optical Coherence Tomography OCT , and to correlate these findings to postoperative visual acuity. Prospective study of consecutive patients hospitalized for macula-off retinal detachment, between February and April , was carried out at the single referral centre for vitreoretinal surgery in Serbia.

All 48 patients with macula-off retinal detachment had undergone clinically successful scleral buckle surgery, 3 to 30 days mean The mean BCVA one month postoperatively was significantly lower pmacula-off retinal detachment who had undergone successful scleral buckle surgery could be explained with presence of submacular fluid, diagnosed by OCT.

However, final visual outcome was favourable, due to the gradual resorption of submacular fluid in a month-period. Submacular hemorrhage in neovascular age-related macular degeneration: A synthesis of the literature.

Large submacular hemorrhage, an uncommon manifestation of neovascular age-related macular degeneration, may also occur with idiopathic polypoidal choroidal vasculopathy. Submacular hemorrhage damages photoreceptors owing to iron toxicity, fibrin meshwork contraction, and reduced nutrient flux, with subsequent macular scarring. Clinical and experimental studies support prompt treatment, as tissue damage can occur within 24 hours.

Reported treatments include retinal pigment epithelial patch, macular translocation, pneumatic displacement, intravitreal or subretinal tissue plasminogen activator, intravitreal anti-vascular endothelial growth factor VEGF drugs, and combinations thereof.

In the absence of comparative studies, we combined eligible studies to assess the VA change before and after each treatment option. Both treatments had an acceptable safety profile, but most studies were small, and larger randomized controlled trials are needed to determine both safety and efficacy.

Published by Elsevier Inc. All rights reserved. Myositis ossificans traumatica in young children: report of three cases and review of the literature. Myositis ossificans traumatica MOT is a rare musculoskeletal disorder in young children.

Clinical and imaging presentation in the early stage of disease makes it difficult to differentiate between infection and musculoskeletal neoplasms, particularly in the absence of a history of trauma. Three cases of MOT in children under the age of 10 years, two with inferential trauma, are presented and the findings on different imaging modalities are discussed with reference to the existing literature.

While findings based on a single imaging technique, including MRI, may be rather non-specific and even misleading, the combination of different modalities can assist in the consideration of MOT as a possible diagnosis. For example, the demonstration of soft-tissue haematoma on US would suggest the traumatic origin. A rational imaging approach is proposed. Gindele, A.

Domingos A. Boldrini", em Campinas-SP. Riego subsuperficial con aguas residuales tratadas. Tissue plasminogen activator-assisted vitrectomy for submacular hemorrhage due to age-related macular degeneration. Full Text Available Purpose: The purpose of this study was to evaluate the treatment efficacy of vitrectomy combined with subretinal recombinant tissue plasminogen activator r-tPA and factors affecting visual improvement in patients with submacular hemorrhage SMH due to neovascular age-related macular degeneration nAMD.

The initial surgical procedure involved a gauge transconjunctival vitrectomy, subretinal r-tPA application through a self-sealing inferior retinotomy, and sulfur hexafluoride gas for tamponade in all patients.

The duration, size, and thickness of the hemorrhage and the pre- and post-operative visual acuity VA using a Snellen chart were recorded. VA was converted to logMAR for statistical analysis. Results: The average duration and size of the SMH were The mean follow-up time was The preoperative thickness of hemorrhage Conclusions: Vitrectomy combined with subretinal r-tPA injection and gas tamponade is an effective surgical intervention to preserve VA in selected patients with apparent SMH.

Successful displacement of a traumatic submacular hemorrhage in a year-old boy treated by vitrectomy, subretinal injection of tissue plasminogen activator and intravitreal air tamponade: a case report.

The natural course of submacular hemorrhage resulting from traumatic choroidal rupture generally has a poor outcome unless treated. The intravitreal injection of gas only or gas with recombinant tissue plasminogen activator rt-PA has been reported to be effective, but has also been reported to induce severe complications such as retinal detachment and vitreous hemorrhage. Recently, we reported a safe and effective procedure for treating submacular hemorrhage due to polypoidal choroidal vasculopathy PCV with a low dose of rt-PA.

Here we report the application of this procedure to a case of traumatic submacular hemorrhage in a year-old boy, which achieved a good visual outcome. A year-old Japanese boy presented with a thick submacular hemorrhage in his left eye as a result of blunt trauma from being hit by a sinker. Best-corrected visual acuity BCVA was assessed as only able to perceive hand motions.

We carried out a vitrectomy, subretinal injection of 4, IU rt-PA 6. The day after surgery, most of the submacular hemorrhage had moved to the inferior periphery. One month after the surgery, we observed cataract formation, thin remnants of the submacular hemorrhage and juxtafoveal choroidal rupture. We carried out cataract surgery and injected bevacizumab intravitreally to prevent the development of choroidal neovascularization.

Vitrectomy, subretinal injection of rt-PA, and intravitreal air tamponade may be a promising strategy for treating traumatic submacular hemorrhage in young patients. Clinicopathologic correlation of submacular membranectomy with retention of good vision in a patient with age-related macular degeneration. We present the clinicopathologic features of the eye of a patient with age-related macular degeneration who underwent submacular membranectomy and had retention of good visual acuity for almost 4 years despite recurrent choroidal neovascularization treated with krypton laser photocoagulation and mild expansion of the laser lesion with time.

Histopathologic study of the surgically removed membrane from the right eye disclosed a thin fibrovascular membrane lined by retinal pigment epithelium on one surface. Microscopic examination of the right eye obtained post mortem disclosed a 2.

Basal laminar deposit was present in the region of the fovea and nasal parafoveal area. Delayed, spontaneous conversion of type 2 closure to type 1 closure following surgery for traumatic macular hole associated with submacular hemorrhage.

Full Text Available A year-old man presented with diminution of vision in the left eye following a firecracker injury. Fundus examination revealed vitreous hemorrhage, a macular hole, and submacular hemorrhage in the left eye.

The clinical findings were confirmed on OCT. Delayed and spontaneous conversion of the traumatic macular hole could occur several months after the primary surgery and may be associated with improved visual outcome.

Larger studies are required to better understand the factors implicated in such a phenomenon.
