Neurosarcoidosis presenting with persistent vomiting

Sarcoidosis is a multi-system granulomatous disease of unknown etiology. It mainly affects the lungs more than other organs, but liver, skin, lymph nodes, and nervous system can be involved. The last is referred to as neurosarcoidosis with a wide range of clinical manifestations depending on the area of the nervous system involved. The differential diagnosis is wide, and the diagnosis, which is based on the histopathology, is sometimes difficult to confirm. Magnetic resonance imaging is the imaging modality of choice for establishing CNS involvement along with the clinical presentation. Cerebrospinal fluid analysis is indicative of the disease activity. We report a 39-year-old man of Indian origin who presented with persistent vomiting for over 2 years due to hypopituitarism and active neurosarcoidosis

Insuficiência renal aguda secundária à sarcoidose / Acute renal failure secondary to sarcoidosis

A sarcoidose é uma doença sistêmica de etiologia desconhecida, caracterizada pela inflamação crônica granulomatosa, que acomete com maior frequencia os pulmões, a pele e os olhos e, muito raramente, detectamos envolvimento renal na patologia. relatamos aqui o caso de uma paciente de 47 anos, branca, internada em uma unidade de emergência de Hospital Universitário, devido a sintomas e achados radiológicos sugestivos de pneumonia. Desde o início da internação ela se apresentava com quadro laboratorial de insuficiência renal aguda, inicialmente atribuída ao histórico recente de uso abusivo de anti-inflamatórios. No entanto, devido à evolução arrastada e aparentemente desfavorável, inclusive com necessidade de terapia renal substitutiva (TRS), a paciente foi submetida a uma biópsia renal para esclarecimento diagnóstico e avaliação prognóstica. A descrição histológica mostrava um quadro de nefrite intersticial aguda granulomatosa, característico de sarcoidose renal, diagnóstico confirmado após revisão do prontuário médico, que revelava internação anterior devido a evento pulmonar da doença. Iniciado tratamento com prednisoma 1mg/kg/dia, a paciente evoluiu com melhora do quadro de insuficiência renal aguda, não mais necessitando de TRS. Atualmente, a paciente é mantida em acompanhamento ambulatorial com função renal estável.

The Sarcoidosis is a systemic disease of unknown etiology characterized by chronic granulomatous inflammation, which affects most frequently the lungs, skin and eyes and very rarely detected renal involvement in pathology. report here the case of a 47 year old white, admitted in an emergency unit of University Hospital because of symptoms and radiological findings suggestive of pneumonia. Since the beginning of hospitalization she performed with a laboratory diagnosis of acute renal failure, initially attributed to the recent history of abuse of anti-inflammatory drugs. However, due to unfavorable prolonged evolution and apparently, also in need of renal replacement therapy (RRT), the patient underwent renal biopsy for diagnosis and prognostic assessment. Histology showed a picture of acute interstitial nephritis, granulomatous characteristic of renal sarcoidosis, confirmed after review of medical records, which revealed previous hospitalization due to lung of the disease. Treatment with Prednisone 1mg/kg/day, the patient presented improvement of acute renal failure, no longer requiring RRT. Currently, the patient is maintained as an outpatient with stable renal function.
