Background: Actinomycosis israeli is a gram-positive non-acid-fast bacterium and is the most common causative agent of actinomycosis. It usually presents as a brain abscess via a secondary spread from the cervicofacial region or lungs. However, presentation as an en-plaque lesion with bone involvement out of proportion to brain parenchyma is rare and needs to be acknowledged. Case Description: We report a case of intracranial en-plaque lesion in a 47-year-old female with restriction of mouth opening and right third nerve palsy for 1 year...

RATIONALE: Thyrotropin-secreting adenoma (TSHoma) is rare, diagnosis and treatment are often delayed if the condition coexists with Hashimoto thyroiditis. The enlarged pituitary adenoma may eventually induce panhypopituitarism, infertility, or the compression of optic nerves and optic chiasma. PATIENT CONCERNS: This patient was a 36-year-old man who had been referred to the pituitary disease multidisciplinary team (MDT) of the West China Hospital, due to infertility...

Background: Keratinous or epidermoid cysts (ECs) are encapsulated lesions lined by squamous cell epithelium. They comprise approximately 1% of intracranial lesions. Contrary to dermoid cysts, they lack dermal elements such as sebaceous or apocrine glands and hair follicles. The sellar region is the second most common intracranial site following the cerebellopontine angle. Here, we report a case of EC in a patient who complained of endocrine disturbances. We also performed a systematic review on previously published cases to analyze clinical and radiological characteristics and report the treatment outcomes of suprasellar ECs...

OBJECTIVE: Secondary cartilage develops from osteochondral progenitor cells. Hypertrophic chondrocytes in secondary cartilage increase within a very short time and then ossify rapidly. In the present study, we investigated the sequential development process of osteochondral progenitor cells, and the morphology and size of hypertrophic chondrocytes in secondary cartilage. DESIGN: ICR mice at embryonic days (E) 14.5-17.5 were used. The mandibular condyle and the medial pterygoid process of the sphenoid bone were observed as secondary cartilage, and the cranial base and the lateral pterygoid process of the sphenoid bone, which is primary cartilage, were observed as a control...

Pituitary apoplexy is a rare clinical presentation caused by infarction of the pituitary gland or adenoma with or without hemorrhage. Although pituitary apoplexy is usually spontaneous, one of the predisposing factors is treatment with dopamine agonists, especially bromocriptine. The occurrence of apoplexy during cabergoline therapy is reported much less frequently. In this article, we report a 34-year-old man with macroprolactinomas who developed sudden visual deterioration due to pituitary apoplexy 1 year after initiation of cabergoline therapy...

Removal of the fronto-orbital bandeau is one of the most critical components for procedures designed to correct anomalies of the craniofacial skeleton and remodel the anterior calvarial vault. It is also used to improve exposure of the anterior cranial fossa. It is arguably one of the more difficult portions of some craniofacial procedures. While the technique for fronto-orbito-sphenoid osteotomy has been frequently described, it has only been minimally detailed. Separation of bone in this region remains challenging due to the bone thickness, adjacent vital structures, and limited direct visibility...

An elderly female with progressive proptosis was found to have an aggressive retrobulbar solid orbital mass. The mass was distinct from the optic nerve sheath and intracranial meninges, and produced concave erosion of the sphenoid wing. Operative findings demonstrated an orbital mass adherent to the dura of the superior orbital fissure. The mass did not demonstrate meningeal violation, infiltrate the superior orbital fissure, or display intracranial spread. The dura remained intact after gross total resection...
