Introduction: Empty sella (ES) is characterized by herniation of the subarachnoid space into the sella turcica, leading to pituitary flattening. Although often considered incidental, ES is increasingly recognized as a radiological marker of idiopathic intracranial hypertension (IIH) which classically presents with headache and visual loss. Importantly, IIH may also present with otolaryngological manifestations such as pulsatile tinnitus, hearing loss, and vertigo. Audiovestibular symptoms have been reported in up to 88.9% of patients with primary ES, with sensorineural hearing loss being the most frequent, while pulsatile tinnitus occurs in approximately 58% of IIH cases. Case: A 51-year-old female presented with 3 months of progressively worsening headaches, rapid deterioration of left-sided hearing, and a 20-kg weight gain over 1 year. Audiometry confirmed moderate left sensorineural hearing loss. Examination revealed a normotensive female with a body mass index of 35 kg/m² and diplopia on left upward gaze without evidence of ophthalmoplegia. The rest of the neurological examination was unremarkable. There was no evidence of papilledema or Cushingoid features. Repeat magnetic resonance imaging brain in 2025 showed persistent partial ES and loss of the posterior pituitary bright spot without an intracranial mass lesion or venous sinus thrombosis. There was no biochemical evidence of hypopituitarism or Cushing’s syndrome. Autoimmune markers were unremarkable. Lumbar puncture demonstrated a mildly elevated opening pressure of 23 mmHg with normal CSF composition. Based on the clinical and radiological findings, early IIH was diagnosed. She was treated with acetazolamide, and prescribed tirzepatide for weight reduction, resulting in improvement in headache and tinnitus. Conclusion IIH can manifest with partial ES and audiovestibular symptoms related to raised intracranial pressure. Early recognition is important, and IIH should be suspected in patients with pulsatile tinnitus or progressive sensorineural hearing loss. Acetazolamide and weight management remain the mainstay of treatment, with emerging evidence supporting a potential role for glucagon-like peptide-1 receptor agonists in reducing intracranial pressure.

Patients with Parkinson’s disease (PD) face a multitude of gastrointestinal (GI) symptoms, including nausea, bloating, reduced bowel movements, and difficulties with defecation. These symptoms are common and may accumulate during the course of PD but are often under-recognized and challenging to manage. Objective testing can be burdensome to patients and does not correlate well with symptoms. Effective treatment options are limited. Evidence is often based on studies in the general population, and specific evidence in PD is scarce. Upper GI dysfunction may also interfere with the pharmacological treatment of PD motor symptoms, which poses significant management challenges. Several new less invasive assessment tools and novel treatment options have emerged in recent years. The current review provides an overview and a practical approach to recognizing and diagnosing common upper and lower GI problems in PD, e.g., dyspepsia, gastroparesis, small bowel dysfunction, chronic constipation, and defecatory dysfunction. Management aspects are discussed based on the latest evidence from the PD and general populations, with insights for future research pertaining to GI dysfunction in PD.
