Cerebellar infarction risk in a mild COVID-19 case.

Thrombotic events in SARS-COV-2 disease patients are frequent, especially in patients with comorbidities such as heart failure, hypertension, cancer, diabetes mellitus, kidney failure, vascular disease, and other pulmonary illnesses. In severe cases, in particular those of hospitalized patients with other comorbidities, the development of thrombotic events in spite of anticoagulation therapy has been observed. The main thrombotic events are pulmonary thromboembolism, cerebral ischemic stroke, and peripheral artery thrombosis.

Transverse myelitis in a 26-year-old male with tuberculosis.

Acute transverse myelitis is an inflammatory condition covering the entire cross section of the spinal cord, spreading on two or more vertebral segments, without evidence of a compressive lesion. This shows clinically as an acute or subacute onset of paraparesis, lower limb paresthesia, sensory deficits, and impaired sphincter function. Mycobacterium tuberculosis is exceedingly rare cause of this inflammation, with a mechanism still not fully understood.

Borderline ovarian tumor and MRI evaluation of a case report.

Borderline ovarian tumors or atypical proliferative tumors are abnormal cells that arise from ovarian epithelium in contrast to ovarian cancers which form from stroma, the supportive tissue of ovaries. They are not invasive and tend to grow slowly. Many patients with BOTs are asymptomatic, while others have nonspecific symptoms like abdominal pain or abdominal distension.

Mixed germ cell tumor of the pineal gland in a pediatric patient.

Tumors of the pineal region are a rare clinical entity, comprising approximately 3%-8% of pediatric tumors. Based on their histopathological features, they are typically classified as pineal parenchymal tumors and germ cell tumors, with the latter being more prevalent. Clinical presentation is heterogeneous, with symptoms arising either due to tumor invasion or compression of adjacent neurovascular structures and increased intracranial pressure.
