Orbital Apex Syndrome caused by invasive aspergillosis in patient with post-Covid-19 infection - A case report.

INTRODUCTION AND IMPORTANCE: Orbital Apex Syndrome (OAS) are characterized by multiple symptoms, such as impaired eye movement, periorbital pain, and visual disturbance. AS symptoms may be caused by inflammation, infection, neoplasm, or a vascular lesion, potentially involving a variety of nerves, such as the optic, oculomotor, trochlear or abducens, or the ophthalmic branch of the trigeminal nerve. However, OAS caused by invasive aspergillosis in post-COVID patient is a very rare phenomenon. CASE PRESENTATION: A 43-year-old male with a history of diabetes mellitus and hypertension who had recently recovered from a COVID-19 infection developed blurred vision on the left eye field, followed by impaired vision on left eye field for 2 months then retro-orbital pain for a further 3 months. The blurring of vision and headache developed soon after recovering from COVID-19 and was progressive in left eye field. He denied any symptoms of diplopia, scalp tenderness, weight loss, or jaw claudication. The patient was treated with IV methylprednisolone for 3 days with as diagnosis of optic neuritis, followed by a course of oral corticosteroid therapy (prednisolone, starting at 60 mg for 2 days and then tapered for 1 month), which produced transient relief of symptoms that recurred when prednisone was discontinued. Then repeat MRI was perform with no evidence of lesion; treated again in a line of optic neuritis and symptoms relief transiently. After reoccurrence of symptoms repeat MRI was perform which showed a heterogeneously enhancing intermediate signal intensity lesion in the left orbital apex. The lesion was encasing and compressing the left optic nerve, without abnormal signal intensity or contrast enhancement within the left optic nerve either proximal or distal to the lesion. The lesion was contiguous with focal asymmetric enhancement in the left cavernous sinus. No inflammatory changes were seen in the orbital fat. CLINICAL DISCUSSION: OAS due to invasive fungal infection is uncommon and most often caused by Mucorales spp., or Aspergillus, particularly in those with immunocompromising conditions or uncontrolled diabetes mellitus. In OAS due to Aspergillosis urgent treatment is necessary to avoid complications such as complete vision loss and cavernous sinus thrombosis. CONCLUSION: OASs, represent a heterogenous group of disorders that results from a number of etiologies. OAS in a background of COVID-19 pandemic can be due to invasive Aspergillus infection as in our patient without any systemic illness and lead to miss diagnosis and delay in proper treatment.

Venture of a Tertiary Care Neurosurgical Center in Course of COVID-19 Lockdown without RT-PCR.

"I will not permit considerations of age, disease or disability, creed, ethnic origin, gender, nationality, political affiliation, race, sexual orientation, social standing or any other factor to intervene between my duty and my patient." Obliged by the aforementioned oath, no medical practitioner shall sit in a moral judgment on any patient but will treat their illness to the best of their ability whatever the circumstances. A clear concord was yet to be authorized after the World Health Organization (WHO) declared the global pandemic of severe acute respiratory syndrome coronavirus 2infection. As a diagnostic modality, WHO recommended real-time reverse transcription-polymerase chain reaction (RT-PCR) as a reliable test; however, its availability in a deprived nation like ours became a major restraining factor. Despite an asset of having high specificity, RT-PCR for coronavirus disease 2019has its own liability of having low sensitivity. Henceforth, as time passed by, the validity of the rapid diagnostic tests was put into question. In later months, a few centers around our periphery started conducting RT-PCR, but the time taken to obtain the result was long-drawn-out process and the patient who needed urgent neurosurgical intervention at Annapurna Neurological Institute and Allied Sciences had to wait. We would like to share our expedition through peaks and valleys of managing 215 patients during the vicious circle of lockdown and global pandemic.

Unusual case of spontaneous bilateral basal ganglia bleed.

Hypertension is the most prevalent determinant condition embarking on the development of spontaneous intracerebral hemorrhage. Usually, the presentation is a unilateral hematoma. Spontaneous bilateral intracerebral hemorrhage is an outstandingly infrequent context, and not a lot of cases have been reported till date. Ensuing hypertension, trauma inflicted on the brain case is another common cause that out turn into the sequelae of bilateral intracerebral hemorrhage. Lately, a few cases of bilateral basal ganglia bleed have been revealed, as a repercussion of COVID-19 infection. Globally, <40 such cases have been reported. A 39-year-old man presented with complaints of acute onset of weakness of right half of the body. Additionally, facial deviation was noticed by his family members. He then sought medical help from a local healthcare center where CT scan of head was advised. Unexpectedly, the scan demonstrated bilateral intracerebral hemorrhage. He was then managed conservatively with oral medications and rehabilitation. The course of his hospital stay was uneventful and was eventually discharged after 9 days. He then presented to our institution for further evaluation. Thereupon, he had slurring of speech but was able to walk with minimal support. Simultaneous Bilateral Basal Ganglia Hemorrhage (SBBGH) is an exceptionally rare ailment. This genre of cerebrovascular accident embraces a comprehensive span of morbidity and mortality. In an acute setting, CT scan of head is the most relevant imaging modality. Nonetheless, MRI is the gold standard for definitive diagnosis and should be performed urgently to further typify and delineate the lesion.

Cerebral venous sinus thrombosis as a complication of COVID-19 infection - A case report.

INTRODUCTION AND IMPORTANCE: Severe acute respiratory distress syndrome coronavirus 2 is the causative agent of COVID-19 (Coronavirus 2019) infection. Although symptoms are usually associated with the respiratory system, its neurological involvement should not be underestimated. The most common cerebrovascular complication following the infection is ischemic stroke however, CVST (Cerebral Venous Sinus Thrombosis) has been reported. PRESENTATION OF CASE: We report a unique case of a young patient who had a history of headache and abnormal body movement immediately after COVID-19 infection. His brain Computed tomography scan and Magnetic Resonance Imaging (MRI) showed typical images of CVST. He was admitted and treated with Low Molecular weight heparin. DISCUSSION: CVST is a rare form of stroke which may have devastating complications. The diagnosis is clinically challenging due to its non-specific presentation like headache and altered sensorium alone. Inflammatory process and hypoxic state after the virus infection may favor the hypercoagulable state in CVST. Our patient did not have any other predisposing factor for a hypercoagulable state other than the COVID-19 infection.MRI and venography and computed tomographic venography are the preferred modalities. The Patient is generally treated with anticoagulation therapy. CONCLUSION: High index of suspicion of CVST is necessary when a patient presents with unexplained neurological manifestation following a recent COVID-19 infection to prevent from life-threatening complications. Furthermore, clinicians should not underestimate the multisystem involvement of COVID-19.
