RESUMO

Ischemic stroke seems to be one of the most serious neurologic complications in patients with COVID-19 infection. Herein, we report a series of 10 ischemic stroke patients with concomitant COVID-19 disease. Out of 10, 8 had large infarcts (3 massive middle cerebral artery, 2 basilar artery, 2 posterior cerebral artery, and 1 internal carotid artery infarct territory). Two had cardiogenic embolic stroke due to atrial fibrillation. Almost half of our patients did not have a vascular risk factor. Nine did not have fever and were diagnosed with COVID-19 upon admission for stroke. Stroke occurred in the first week of respiratory symptoms with moderate pulmonary involvement. Most Patients did not have hypoxia and did not establish respiratory failure or acute respiratory distress syndrome. The blood pressures were low and hemorrhagic transformation did not occur even after antiplatelet or anticoagulant therapy. Patients had markedly increased levels of lactate dehydrogenase, C-reactive protein, and D-dimer. Three patients died. It seems that ischemic strokes in COVID-19 patients tend to occur as large infarct and can be seen in patients with mild to moderate pulmonary involvement.

RESUMO

Amongst the neurologic complications of COVID-19 disease, very few reports have shown the presence of the virus in the cerebrospinal fluid (CSF). Seizure and rarely status epilepticus can be associated with COVID-19 disease. Here we present a 73-year-old male with prior history of stroke who has never experienced seizure before. He had no systemic presentation of COVID-19 disease. The presenting symptoms were two consecutive generalized tonic-clonic seizures that after initial resolution turned into a nonconvulsive status epilepticus despite antiepileptic treatment (a presentation similar to NORSE (new-onset refractory status epilepticus)). There was no new lesion in the brain magnetic resonance imaging (MRI). The CSF analysis only showed an increased protein levels and positive reverse transcription polymerase chain reaction (RT-PCR) of 2019-nCoV. Patient recovered partially after anesthetic, IVIG, steroid, and remdesivir. To our knowledge, this is the first report of a refractory status epilepticus with the presence of SARS-CoV-2 ribonucleic acid (RNA) in the CSF.

RESUMO

Purpose: We aimed to investigate empty sella syndrome in somatotrophic pituitary adenoma for possible etiology, complications, and treatment options. Method: Among over 2,000 skull base masses that have been managed in our center since 2013, we searched for growth hormone-producing adenomas. Clinical, surgical, and imaging data were retrospectively collected from hospital records to check for sella that lacked pituitary tissue on routine imaging. Result: In 220 somatotrophic adenomas, 23 patients had an empty sella with surgical and follow-up data. The mean age of the sample was 46 years with the same male-to-female ratio. Five cases had partial empty sella and the rest were complete empty sellas. The most common simultaneous hormonal disturbance was high prolactin levels. Six had adenoma invasion into the clivus or sphenoid sinus and 10 had cavernous sinus intrusion. Peri-operative low-flow and high-flow cerebrospinal fluid (CSF) leaks were encountered in one and two patients, respectively, which were successfully sealed by abdominal fat. The majority of cases required growth hormone replacement therapy while it was controlled without any replacement therapy in nine patients. No pituitary hormonal disturbance occurred after transsphenoidal surgery except for hypothyroidism in one patient. Conclusion: An empty sella filled with fluid can be detected frequently in pituitary adenomas, especially in the setting of acromegaly. The pituitary gland may be pushed to the roof of the sella and might be visible as a narrow rim on imaging or may be detected in unusual places out of the sella. The pathophysiology behind such finding originates from soft and hard tissue changes and CSF pressure alternations during abundant growth hormone production.

RESUMO

Mucormycosis is an opportunistic infection that has become a serious concern as a result of the immunosuppressive drugs used during COVID-19. In this report, we describe two cases of rhino-orbital-cerebral mucormycosis with neurological presentation and ophthalmologic problems accompanied by a history of COVID-19 and diabetes.
