Schwannomas are common tumors of the head and neck region, but they rarely develop in the suboccipital region. A 34-year-old woman presented with a left suboccipital mass causing local pain and neck stiffness. Following physical examination, fine needle aspiration biopsy was performed, which revealed benign cytology. In the light of preoperative radiologic examination and intraoperative observations, the lesion was thought to originate from the greater occipital nerve. Following complete excision of the lesion, histopathological diagnosis was made as schwannoma. Apart from mild neck stiffness and transient local paresthesia in the early postoperative period, no complications were seen during a two-year follow-up period.

Background: White matter hyperintensities (WMH) have been implicated in the pathogenesis of neuropsychiatric symptoms of dementia but the functional significance of WMH in specific white matter (WM) tracts is unclear. We investigate whether WMH burden within major WM fibre classes and individual WM tracts are differentially associated with different neuropsychiatric syndromes in a large multicentre study.
Method: Neuroimaging and neuropsychiatric data of seven memory clinic cohorts through the Meta VCI Map consortium were harmonised.

This study reports a rare case of referred pain in the trigeminal nerve distribution caused by entrapment of the greater occipital nerve (GON). Notably, the pain extended to the ipsilateral tongue, an unusual intraoral involvement. GON entrapment can lead to sensitization in secondary nociceptive neurons within the trigeminocervical complex (TCC), which receives signals from both trigeminal and occipital nerves, causing referred facial pain.

Most common type of hair loss is androgenetic alopecia. Orentreich's donor dominance theory and the definition of safe donor area are the theoretical foundation of modern hair transplantation. In safe donor area no progression of permanent hair loss occurs.

Patients with major depressive disorder (MDD) and borderline personality disorder (BPD) are reported to have disrupted autobiographical memory (AM). Using functional magnetic resonance imaging we investigated behavioral and neural processing of the recall of emotional (sad and happy) memories in 30 MDD, 18 BPD, and 34 healthy control (HC) unmedicated women. The behavioral results showed that the MDD group experienced more sadness than the HC after the sad recall, while BPD participants experienced less happiness than HC after the happy recall.

Objective: Obsessive-compulsive disorder (OCD) is associated with altered brain function related to processing of negative emotions. To investigate neural correlates of negative valence in OCD, we pooled fMRI data of 633 individuals with OCD and 453 healthy controls from 16 studies using different negatively-valenced tasks across the ENIGMA-OCD Working-Group.
Methods: Participant data were processed uniformly using HALFpipe, to extract voxelwise participant-level statistical images of one common first-level contrast: negative vs.
