Paracoccidioidomycosis in the Central Nervous System

Paracoccidioidomycosis is a systemicmycosis caused by the Paracoccidioides brasiliensis fungus, which is endemic in Latin America. Brazil is the country with the highest number of cases. The affection of the central nervous system (CNS), a potentially fatal condition, occurs in 12% of the cases. The following forms of presentation are identified:meningeal, which is unusual;meningoencephalitic; and pseudotumoral, the latter two being more frequent. Imaging tests are essential for the diagnosis, but the histological identification of the fungus is required for confirmation of the pathology. The clinical picture depends on the neuraxial location.We present a case of amale rural worker, with expansive lesions in the CNS compatible with paracoccidioidomycosis.

Diagnosis at different stages of paracoccidioidomycosis with oral manifestation: Report of two cases.

Paracocciodiomycosis (PCDM) is a chronic systemic fungal infection, mainly affecting residents and rural workers, being characterized by a long incubation period, which it can take months or years without clinical manifestations, making diagnosis late and difficult. Depending on the stage of the disease, it can cause sequelae and low quality of life, so its correct diagnosis is of great importance for the accurate treatment. Therefore, the aim of this report is to present two cases of diagnosis of patients with PCDM at different stages, who developed chronic manifestations, pain, clinical involvement of the oral cavity and in one case also presented lung injury with fibrosis, as well as to weight loss, dysphagia and cachexia. Both of patients were treated with antifungal therapy and it was observed total remission of the lesions and no recurrences were detected.

Complex nasal reconstruction after paracoccidioidomycosis infection--Case report.

Paracoccidioidomycosis is an infectious disease whose etiological agent belongs to the Paracoccidioides genus. Although it affects primarily the lungs, it can spread to other tissues, including the skin and mucous membranes. Despite the clinical treatment for this disease, scarring can produce sequelae, manifesting as anatomical and functional deformities of the face. We present a case of extensive, nasal unaesthetic and functional sequelae resulting from paracoccidioidomycosis, reconstructed using the paramedian forehead flap in three stages, through the regional unit principles.

Surgery for other pulmonary fungal infections, Actinomyces, and Nocardia.

Surgical participation in the management of fungal infections has changed since the advent of effective antimicrobials. Even so, a surgeon may be called on for a variety of reasons, depending on the specific fungal infection and the evolution of thoracic disease. Specific fungal infections are enumerated. Each organism, its clinical picture, and method of diagnosis are briefly described and the medical and surgical management of thoracic disease are discussed.

Balloon-assisted clipping of a large paraclinoidal aneurysm: a salvage procedure.

OBJECTIVE: Surgical clipping and parent vessel reconstruction of wide-neck paraclinoid aneurysms can be very challenging. We report a case of a ruptured paraclinoid aneurysm which failed standard clipping techniques. We were able to reconstruct this aneurysm while providing proximal and distal control using an adjuvant endovascular balloon. CLINICAL PRESENTATION: We report the case of a 45-year-old woman presenting with a ruptured large paraclinoidal aneurysm, which involved a significant portion of the internal carotid artery wall. INTERVENTION: Repeated attempts at fenestrated clip placement resulted in slipping of the clip and occlusion of the parent artery. Ultimately, the aneurysm ruptured at the neck, and, despite trapping and direct aneurysmal suction decompression, significant bleeding was encountered. The bleeding point was packed, and, subsequently, endovascular access was obtained. A balloon was navigated and then inflated across the neck of the aneurysm using C-arm fluoroscopic guidance. The aneurysm was successfully clipped, and intraoperative angiography demonstrated no parent vessel stenosis. CONCLUSION: This case demonstrates a salvage procedure in the event of intraoperative rupture and inadequate interruption of local blood flow. Balloon inflation resulted in adequate hemostasis and provided intraluminal support for optimal clip placement while preserving the parent artery.

Paracoccidioidomicose em hemisfério cerebral e tronco encefálico: relato de caso / Paracoccidioidomycosis in cerebral hemisphere and brainstem: case report / Paracoccidioidomycosis in cerebral hemisphere and brainstem: case report

Relata-se sobre um homem de 36 anos com passagem quatro anos antes pela selva amazônica. Admitido após seis meses do aparecimento progressivo de tetraparesia, ataxia de marcha, disfagia, disartria, dispnéia e soluço. A ressonância magnética revelou lesão parietoccipital à direita e no bulbo, sendo esta última maior. Investigações para tuberculose e síndrome da imunodeficiência adquirida tiveram resultados negativos. Foi submetido a microcirurgia da lesão do bulbo. O estudo anatomopatológico revelou paracoccidioidomicose. Recebeu tratamento com anfotericina B até 2100 mg, e sulfametoxazol-trimetoprim por três meses, e fisioterapia. Voltou às atividades após seis meses do término do tratamento. Comenta-se sobre a participação do sistema imunológico e das citocinas (interleucinas.

We report on a 36 years-old man that had been at the Amazon forest four years before. Six months before the admission he had developed a progressive quadriparesis, gait ataxia, dysphagia, dysarthria, difficulty in breathing and hiccup. The gadolinium-enhanced T1-weighted MRI showed a lesion into the right parietoccipital area and another into the medulla, that was the largest. There was any evidence of tuberculosis or AIDS. The patient was submitted to microsurgical approach to the medulla. Pathological examination revealed paracoccidioidomycosis. Treatment with anphotericin B till 2100mg was administered followed by sulfamethoxazole-trimetoprim for three months plus physical therapy. The patient went back to his activities six months after the end of the treatment. Comments are presented about the participation of the immunological system and of the cytokines (interleukines.

Ocular and central nervous system paracoccidioidomycosis in a pregnant woman with acquired immunodeficiency syndrome.

PURPOSE: To describe an atypical case of central nervous system and ocular paracoccidioidomycoses simulating ocular toxoplasmosis in a pregnant woman with acquired immunodeficiency syndrome (AIDS). DESIGN: Interventional case report. METHODS: Case report. RESULTS: A 25-year-old pregnant woman with AIDS, presented with a severe ocular inflammation in the right eye involving the choroid, retina, and the optic disk, which rapidly progressed to retinal detachment, iris neovascularization, and neovascular glaucoma. The left eye was normal. Magnetic resonance imaging (MRI) showed a focal hypodense contrast-enhanced ring lesion in the brain. Serum antibody titers were negative for Toxoplasma gondii, but the polymerase chain reaction was positive for the parasite in the vitreous sample. The patient responded partially to specific treatment for toxoplasmosis, and there was a small reduction in size of the brain lesion. She progressed to a blind painful eye, which was enucleated. Paracoccidioides brasiliensis was found in the histopathological studies of the eye and oropharynx. With the diagnosis of disseminated ocular paracoccidioidomycoses, the patient was treated with trimethoprim-sulfamethoxazole with a satisfactory outcome and reduction in size of the brain lesion. CONCLUSION: Although ocular infection with ocular paracoccidioidomycoses is rare, this diagnosis should be considered when investigating ocular inflammation in a patient with AIDS.

Report of the first human case of lobomycosis in the United States.

We describe the first human case of lobomycosis caused by Lacazia loboi in a 42-year-old white male resident of Georgia. The patient had traveled to Venezuela 7 years earlier, where he had planned to rappel down Angel Falls in Canaima. Although he never actually rappelled the falls, he did walk under the falls at least three times, exposing himself to the high water pressures of the falls. He noticed a small pustule with surrounding erythema developing on the skin of his right chest wall. The lesion gradually increased in size and had an appearance of a keloid. For cosmetic reasons, the patient sought medical treatment to remove the lesion. After an uncomplicated excision of the lesion, the patient recovered completely. The excised tissue was fixed in formalin for pathologic examination. Tissue sections stained by hematoxylin and eosin, periodic acid-Schiff stain, and Gomori methenamine silver stain procedures showed numerous histiocytes, multinucleated giant cells, and numerous globose or subglobose, lemon-shaped cells producing multiple blastoconidia connected by narrow tube-like connectors and catenate chains of various lengths characteristic of L. loboi.

Osteomielite blastomicótica costal localizada ocasionando sépsis e tratamento cirúrgico / Localized costal blastomicotic osteomyelitis leading to sepsis and its surgical treatment

Os autores apresentam um caso de osteomielite de 7ª e 8ª costelas em hemitórax direito, sem comprometimento pulmonar evidente, com evoluçao progressiva para abscesso de parede torácica e sépsis. Costectomias parciais imediatas e antibioticoterapia endovenosa foram o tratamento de escolha, com análise histopatológica óssea revelando presença maciça de colônias de Paracoccidioides brasiliensis e, complementaçao com tratamento medicamentoso específico estabeleceu critérios de cura. O presente trabalho evidencia a raridade da localizaçao fúngica, a dificuldade clínica na investigaçao diagnóstica, devido a ausência de pneumopatia prévia aparente, e a importância do exame microscópico na conduçao da escolha terapêutica adequada.

Palpebral paracoccidioidomycosis.

This paper describes two cases of eyelid paracoccidioidomycosis (South American blastomycosis) in which it was the first signal of the disease. In both cases the first clinical diagnosis made was not a fungal infection, but a neoplastic disease that was not confirmed by the pathology study. In the first patient we suspected a primary infection on the eyelid, because there was no other systemic signs of the disease, and in the second patient we noted a very advanced pulmonary lesions caused by the Paracoccidioides brasiliensis. We believe that, in endemic areas, the histopathological study should be made before every excisional procedures to avoid unnecessary palpebral mutilation.

Intramedullary spinal cord paracoccidioidomycosis. Report of two cases.

Two cases of intramedullary paracoccidioidomycosis are reported. Paracoccidioidomycosis is a systemic disease that involves the buccopharyngeal mucosa, lungs lymph nodes and viscera and infrequently the central nervous system. Localization in the spinal cord is rare. Case 1: a 55-year old male admitted with crural pararesis, tactile/painful hypesthesia and sphincter disturbances of 15 days duration. Cutaneous-pulmonary blastomycosis was diagnosed 17 years ago. Myelotomography showed a blockade of T3-T4 (intramedullary lesion). The lesion surgically removed was a Paracoccidioides brasiliensis granuloma. Treatment with sulfadiazine was started after the surgery. Follow-up of 15 month showed an improvement of the clinical signs. Case 2: a 57-year old male was admitted elsewhere 6 months ago and, with a radiologic diagnosis of pulmonary paracoccidioidomycosis, was treated with amphotericin B. He progressively developer paresthesia and tactile/pain anaesthesia on the left side, sphincter disturbances and tetraparesis with bilateral extensor plantar response and clonus of the feet. Myelotomography showed a blockade of C4-C6 (intramedullary lesion). The lesion was not found during surgical exploration and the patient deteriorated and died. Post-mortem examination revealed an intramedullary tumor above the site of the mielotomy (Paracoccidioides brasiliensis granuloma). The preoperative diagnosis of intramedullary paracoccidioidomycotic granulomas is difficult because the clinical and radiologic manifestations are uncharacteristic. Clinical suspicion was possible in our cases based on the history of previous systemic disease. Contrary to intracranial localizations, paracoccidioidomycotic granulomas causing progressive spinal cord compression may require early surgery because response to clinical treatment is slow and the reversibility of neurological deficits depends on the promptness of the decompression.

Thoracic intraspinal Paracoccidioidomycosis. Case report.

Intramedullary lesions caused by Paracoccidioides brasiliensis have been rarely described. Its diagnosis may be challenging and surgical approach is indicated for diagnostic and therapeutic purposes. We hereby report a case with MRI and surgical findings in a 45 year-old woman with intramedullary paracoccidioidomycosis, and make a review of other cases presented in the literature.
