ABSTRACT
Congenital anophthalmia is rare and can occur due to various etiologies, including genetic defects, teratogenic exposures, and vascular disruptions. We report a rare case of right-sided congenital anophthalmia and hemicerebral dysgenesis in association with ipsilateral hemicerebral vascular dysgenesis in a neonate. Postnatal neuroimaging was conspicuous for a "bare orbit sign." A unilateral cranial neurocristopathy was suspected to be an underlying etiopathology for such a diffuse defect.

A 53-year-old female admitted to the hospital for generalized weakness, fever, and cough, tested positive for coronavirus disease 2019 (COVID-19). She experienced cardiac arrest and then developed a deep-venous thrombosis and pneumonia. She then developed new-onset paraplegia due to an epidural abscess found on thoracic-spine imaging. After surgical removal of the epidural abscess, the patient improved clinically. This is a unique case report of a patient developing paraplegia secondary to an epidural abscess as a serious complication of COVID-19 infection.
ABSTRACT
Atypical central neurocytoma with extracranial metastases is a rare variant of benign central neurocytoma (CN). No definitive course of treatment exists for atypical CN. We report a unique case of atypical CN with concomitant pituitary macroadenoma and subsequent metastases to the spine. The patient received craniospinal radiation therapy. Close-follow up post tumor-resection may be advised to monitor for drop metastases. To the best of our knowledge, this is the only case reported of atypical CN with drop metastases to the spine concomitant with pathological-proven pituitary macroadenoma.
ABSTRACT
The study assessed changes in cerebral blood flow and need for chronic blood transfusions in sickle cell disease children after splenectomy. A retrospective chart review of 40 children splenectomized between 1999 and 2014 was performed. The mean time-average maximum velocity before splenectomy was 129 cm/sec; which increased to 157 cm/sec and then decreased to 137 cm/sec, 2 and 5 years postsplenectomy, respectively. There was a persistent and statistically significant elevation in platelet count noted after splenectomy. The mean cerebral blood flow velocity seemed to increase transiently after splenectomy. Close monitoring and screening for stroke risk should be continued postsplenectomy.
