Absent right common carotid artery with associated anterior communicating aneurysm: embryology and imaging correlation.

Purpose: To report an unusual absent right common carotid artery with embryological and clinical emphasis.

Methods: A 63-year-old female with a multilobulated anterior communicating artery saccular aneurysm was referred to our center for definite treatment. An analysis of her carotid system on CTA and DSA with 3D modeling was performed to assess the embryology of an absent right common carotid and its association with aneurysm development.

Central nervous system embryonal tumor with PLAGL1 amplification: a case report of a novel entity focusing on imaging findings.

The embryonal central nervous system (CNS) tumor with PLAGL1 (pleomorphic adenoma gene-like) amplification is a novel type of pediatric neoplasm with a distinct methylation profile, described for the first time in 2022. It may be located anywhere in the neuroaxis and, as its name implies, it is driven by the amplification and overexpression of one of the PLAG family genes. Although the associated clinical, immunohistopathological, and molecular characteristics are well characterized in the seminal report of this entity, data on the radiological features is still lacking.

Modification of Gene Expression of Tomato Plants through Foliar Flavonoid Application in Relation to Enhanced Growth.

The exogenous application of phenolic compounds is increasingly recognized as a valuable strategy for promoting growth and mitigating the adverse effects of abiotic stress. However, the biostimulant effect under optimal conditions has not been thoroughly explored. In this study, we investigated the impact of foliar application of flavonoids, specifically CropBioLife (CBL), on tomato plants grown under controlled conditions.

An atypical location of pineoblastoma RB1 subgroup without pineal or retinal tumor.

Purpose: To describe the clinical and imaging features of a sellar-suprasellar pineoblastoma RB1 subgroup without pineal or retinal involvement.

Case Report: An 11-month-old girl presented to the emergency department with fever, rhinorrhea, vomiting, altered level of consciousness, and one seizure. Head CT and brain MRI demonstrated a large lobulated mass with calcifications and heterogeneous enhancement in the suprasellar region causing mass effect to the ventricular system and hydrocephalus.

A bicarotid trunk with associated right retroesophageal subclavian artery in a child with neurofibromatosis type 1 complicated by a left hemispheric stroke.

Purpose: To describe the association between two aortic arch branch variants and its possible relationship with neurofibromatosis-1.

Methods: A 5-year-old female with NF-1 diagnosis presented to the emergency department at 2 months of age with irritability, vomiting and left gaze deviation. Brain MRI showed a left side acute hemispheric stroke and left internal carotid occlusion.

Intradural Extramedullary Tumors and Associated Syndromes.

Most intradural tumors are located within the intradural extramedullary compartment, and the most common tumors are schwannomas and meningiomas. Other less common neoplasms include neurofibroma, solitary fibrous tumor, myxopapillary ependymoma, lymphoma, metastatic leptomeningeal disease, malignant peripheral nerve sheath tumor, and paraganglioma. Patients usually present with gait ataxia, radicular pain, and motor and sensory deficits due to chronic compressive myelopathy or radiculopathy.

Multiple sclerosis with megacystic presentation: A case report.

Multiple sclerosis is a frequent condition where the diagnosis relies on clinical presentation, neurologic examination, cerebro spinal fluid markers, and diagnostic imaging tests; however, atypical variants of the disease can lead to misdiagnosis in some scenarios. Herein, we describe a case of a 24-year-old patient with multiple sclerosis with megacystic plaques, in which appropriate interpretation of the imaging findings lead to a proper diagnosis and treatment.

Draft Genome Sequence of Pseudomonas mandelii Strain 29, Isolated from the Desert Truffle Terfezia claveryi.

Here, we report the genome sequence of the mycorrhizal helper bacterium (MHB) Pseudomonas mandelii strain 29. This is the genome of an MHB associated with ascocarps of the desert truffle Terfezia claveryi. The genome is complete and consists of 6,302,122 bp and 5,812 predicted protein-coding sequences.

High jugular bulb with a diverticulum and vestibular aqueduct dehiscence: an anatomical variant to be aware in patients with hearing loss.

Purpose: To describe an anatomical variant that should be consider in patients with hearing loss.

Methods: An 8-year-old girl underwent to temporal bone computed tomography for the evaluation of bilateral conductive hearing loss and further assessment of possible enlarged vestibular aqueduct or high jugular bulb on brain magnetic resonance imaging (MRI).

Results: CT of temporal bone showed a cystic cavity with bony sclerotic margins extending from the right jugular foramen to the vestibular aqueduct.

Papilledema: A Review of the Pathophysiology, Imaging Findings, and Mimics.

Increased intracranial pressure is the most common cause of papilledema. Multiple etiologies such as cerebral edema, hydrocephalus, space occupying lesions, infection, and idiopathic intracranial hypertension among others should be considered. Imaging plays a critical role in the detection of pathologies that can cause papilledema.
