Angiolipomas are rare benign mesenchymal tumours, most commonly found in the subcutaneous tissue of the extremities. These neoplasms are rarely located in the central nervous system (CNS), with spinal localization being the most common in this group. Intracranial location is extremely infrequent, and only ten cases have been described in the sellar region. We report on two more patients with skull-base (intracranial) angiolipomas, the former presented with a long history of headache and the latter complained diplopia. Both patients were postoperatively verified as angiolipoma. Neuroimaging studies and peroperative features are presented and the role of microsurgery is discussed. On the basis of these tumours' characteristics, the management strategy of choice usually does not consist on surgical total removal, often a partial excision could be satisfying to improve the patient symptomatology. Nowadays, Gamma Knife surgery is standing out as an effective, additional and/or alternative, treatment modality.

Transcription factors (TFs), including steroidogenic factor-1 (SF-1), T-box transcription factor (TPIT) and pituitary transcription factor-1 (PIT-1), play a pivotal role in the cytodifferentiation of adenohypophysis. However, the impact of TFs on the growth patterns of nonfunctioning pituitary adenomas (NFPAs) remains unclear. This study aims to investigate the correlation between the expression of TFs and NFPAs growth patterns.

Background And Objectives: Sinonasal fungal balls (FBs) most commonly occur in the maxillary sinus, followed by the sphenoid sinus (SS). Relatively little is known about the predisposing factors and pathogenesis of unilateral sphenoid sinus fungal balls (SSFBs) compared to maxillary sinus FBs. We investigated whether anatomical variations have clinical implications for the location of unilateral SSFBs.

Background And Objective: Endoscopic endonasal approaches to treat cavernous sinus lesions require detailed knowledge of the origin, course, and anatomic variations of the branches of the cavernous internal carotid artery (cICA) because inadvertent avulsion can cause intraoperative ICA injury. We aim to study the origin and course of the branches of the cICA from an endoscopic endonasal perspective and relate these branches to surgically relevant anatomic references.
Methods: Sixty sides of 30 formalin-fixed specimens were dissected to identify the origin and course of cICA branches, including the inferolateral trunk (ILT), the meningohypophyseal trunk (MHT), anterior and inferior McConnell's capsular arteries (MCAs), and the superolateral trunk (SLT).

Objective: This study aims to compare sphenoid sinus variations between unilateral and bilateral cleft lip and palate (CLP) patients and healthy controls using CBCT images. It is notable for its large sample size and comparison of unilateral and bilateral cleft patients, cleft and noncleft sides, and different age groups.
Design: Retrospective cohort study.
