A Case Report of Ruptured Intracranial Dermoid Cyst.

Intracranial dermoid cysts, rare congenital lesions originating from ectodermal elements during neural tube closure, are explored in the context of a 45-year-old female presenting with a sudden-onset severe headache, nausea, and vomiting. A thorough neurological examination revealed no focal deficits, prompting a computed tomography scan that identified multiple extra-axial intracranial fat density lesions indicative of dermoid cysts. Laboratory and cerebrospinal fluid analysis confirmed inflammatory changes, characterized by an increased white blood cell count. Successful surgical intervention followed, resulting in the complete removal of the cyst and the patient's subsequent full recovery with the resolution of symptoms. This case highlights the intricate nature of intracranial dermoid cysts and underscores the critical importance of prompt recognition in effectively mitigating potential complications.

A Rare Case of Solitary Schwannoma of Submandibular Gland.

Tumors of the salivary gland constitute a heterogeneous group of variable histological and biological behaviors. Patients with salivary gland tumors typically present with painless swelling. However, several neoplastic and non-neoplastic pathologies can result in salivary gland enlargement. We report the case of a 35-year-old woman complaining of a left neck swelling for 3 months duration. She had no relevant past medical or surgical history. On examination, there was a left submandibular swelling that was firm in consistency, non-tender, non-pulsatile, relatively mobile, and was not tethered to the underlying structures. Otherwise, examination of the head and neck was unremarkable. A CT scan of the neck revealed a well-defined hypodense lesion in the left submandibular region with foci of calcification along with multiple enlarged lymph nodes. After surgical exploration, the submandibular gland region, a mass lesion was found arising from the submandibular gland. Histopathological examination revealed the diagnosis of schwannoma. Salivary gland schwannoma is a very rare form of neurogenic tumor. Surgical resection is the treatment of choice; however, neural deficits are important and common postoperative complications.
