 Good morning everyone. Myself Dr. Surajit Chan. I am a third-year resident from Department of Radio Diagnosis, University College of Medical Science and Gurudwagadur Hospital, New Delhi. Title of my paper presentation is Spectrum of Sarcoidosis, a rare case report of Neurosurpretysis. Introduction. Sarcoidosis is a systemic disease with multiple non-casiating grandmas. Most commonly affected organs are lungs, followed by lymph nodes, oculosarcoidosis in. It is most commonly seen in the middle-aged females. Neurologic manifestation is rare and appears in within two years. Cranial neuropathies are the most common presentation. Seventh nerve being the most common nerve involved, followed by eighth and second nerve. Meningeal involvement like aseptic meningitis and neural braceletion, neuropathy and encephalopathy are the other common presentation of Neurosurpretysis. Aim and methodology. Aim of the study is to evaluate the role of MDCT in suspected case of sarcoidosis. Patient underwent CCT head, orbit and chest in the Department of Radio Diagnosis in USMSGTB Hospital. Taste presentation. It is a case of a 30-year-old male patient with no previous medical history. Patient presented to the outpatient clinic with complaint of redness, pain, blurring of vision in the red eye for five to seven days. There was associated fever, headache, chest pain and involuntary weight loss over the last three months. No, there was no history of facial deviation and hemoptasis. On examination, we can see in this picture that there is an iris nodule with hemorrhage seen in the right eye. Patient underwent lumbar puncture. However, there is only a slight increase in the CSF pressure. The sugar and the protein levels were normal. On neurological examination, there were no cranial nerve pulse noted. Plasma and CSF ACA levels were normal. Patient underwent sputum cibinate and serum ADA. Both of them were not positive for TB. Onto-antibody testers were done. ANA and ankle levels were normal. Cryptococcal antigen levels were normal. These all the tests were done to rule out other granulomatous infections. Here in these images, we can see this is a CCT image of axial and coronal section. There are multiple homogeneously enhancing limb nodes seen in the medial stenum, mainly in the right paratracheal region, pre-vascular region, pre-carinal region, and bilateral hyaluridin. There is similar limb node also seen in the periportal region. The same patient underwent CCT head also and we can see there are a lobilated multiple homogeneously enhancing lesion. It is durol based lesion with broad base towards tibra which can be seen as orange arrow in axial and coronal, axial and sagittal section. There is surrounding vasogenic edema involving the white matter which is marked as green arrow. And in this fourth image, we can see there is no underlying hypostasis of the bone. We did histopathology from the endobonchial biopsy and bronchial vela laser. In this image, we can see there are multiple well-defined granulomers with surrounding naked limb nodes which is marked as green arrows, size-tip of non-necrotizing granulomers. Discussion. Neurologic involvement in the circuitry is uncommon. However, it can serve wide variety of presentation. Both clinically and radiologically, it can be difficult to diagnose. Histology confirmation of non-casiating granulomers is needed to support the diagnosis. It is important to rule out other etiologies of granuloma information, like tuberculosis, fungal infection and autoimmune diseases. A major challenge in the neurocircuitosis diagnosis is the difficulty to obtain nerve tissue for histology and microbiologic analysis. Neurocircuitosis can be assumed in patients with confirmed circuit involvement of the other organs and neurologic symptoms. In our case, we can confirm the diagnosis by finding non-necrotizing granulomers in endobonchial biopsy and bronchial vela laser. In our case, the patient was administered pedicillin 40 mg BD for two months and her symptoms improved significantly. The significant improvement seen after therapy highlights the importance of the awareness towards the clinical entity in order to start the treatment as early as possible. Here are my references. Thank you.
