BACKGROUND: Literature reports on ophthalmological manifestations related to tularemia, a zoonose caused by the bacterium Francisella tularensis, largely refer to Parinaud's oculoglandular syndrome, which consists of the association of conjunctivitis with preauricular lymphadenitis. In this paper, we report a case of intraocular inflammation during tularemia infection. CASE PRESENTATION: A 52-year-old Caucasian man was diagnosed with unilateral uveitis. The uveitis was posterior, with a 2+ vitritis and a large yellowish lesion involving the macula with an overlying sub-retinal detachment, extending inferiorly, and subretinal hemorrhages...

Parinaud's syndrome, also known as dorsal midbrain syndrome, includes multiple clinical signs, with the most prominent being paralysis of upward gaze. This syndrome has most commonly been described in association with pineal region masses. Other relatively common causes of this syndrome include hydrocephalus, intrinsic midbrain masses, and ischemic lesions. MRI is very helpful in determining the cause and thus guiding appropriate treatment.

Neoplasms of the pineal region comprise less than 2% of all intracranial lesions. A variety of techniques have been adapted to gain access to the pineal region. Classic approaches employ the use of the microscope. More recently, the endoscope has been utilized to improve access to such deep-seated lesions. A 62-year-old female presented with a heterogeneously enhancing lesion in the pineal region with associated hydrocephalus. On exam, the patient exhibited Parinaud's syndrome. The patient initially underwent a single burr hole endoscopic third ventriculostomy and biopsy of the lesion...

We present a case of longstanding, undiagnosed spontaneous intracranial hypotension (SIH) with an acute presentation of Parinaud's syndrome, in whom serial imaging demonstrated development of a midbrain mass. The patient was ultimately diagnosed with tumefactive venous infarction secondary to SIH. However, this patient underwent a brainstem biopsy, which in retrospect may have been avoidable. This case demonstrates the imaging features of tumefactive venous infarction in SIH and highlights the risk of misinterpretation as a neoplasm with potentially catastrophic consequences...

This is the first reported case of pineal lymphoma with concomitant prolactin-producing pituitary adenoma.A 51-year-old male experienced worsening headaches accompanied by nausea, diplopia, and memory loss for 1 month. Cranial nerve examination revealed bilateral upward gaze limitation with convergence impairment, which is known as Parinaud syndrome. Magnetic resonance images revealed a mass in the pineal gland with a coexisting mass within the enlarged sella fossa. Hormone analysis revealed hyperprolactinemia...

CLINICAL CASE: A 33-year-old male diagnosed with Parinaud's syndrome, exotropia and post-papillary oedema optic atrophy in his left eye. A pineal germinoma was diagnosed after performing neuroimaging scans and a stereotactic biopsy. He was treated with chemotherapy and radiotherapy, showing a complete pathological response. The Parinaud's syndrome persists one year after diagnosis and the patient has refused to have strabismus surgery. DISCUSSION: Parinaud's syndrome consists of a supranuclear vertical gaze palsy resulting from damage to the midbrain tectum...

BACKGROUND: A pineal cyst is a benign affection of a pineal gland on the borderline between a pathological lesion and a variant of normality. Clinical management of patients with a pineal cyst remains controversial, especially when patients present with non-specific symptoms. METHODS: An online questionnaire consisting of 13 questions was completed by 110 neurosurgeons worldwide. Responses were entered into a database and subsequently analysed. RESULTS: Based on data from the questionnaire, the main indication criteria for pineal cyst resection are hydrocephalus (90 % of the respondents), Parinaud's syndrome (80 %) and growth of the cyst (68 %)...

Pinealoblastomas are WHO grade IV tumors of the pineal region and comprise up to 50% of all pineal parenchymal tumors. They are highly aggressive tumors that spread along the craniospinal axis and are most commonly seen in children. The standard of care involves maximal surgical resection and chemoradiation following tissue diagnosis. We present the rare case of a large pinealoblastoma in an 18-year-old girl who presented with headaches and Parinaud's syndrome from tectal compression. An attempt was made at endoscopic transventricular biopsy of the tumor at an outside hospital, but it was aborted given bleeding at the biopsy site...

BACKGROUND: Surgical treatment for lesions in the posterior third ventricle is technically challenging. Surgical approaches to this area carries a risk of both venous and neural injury, with subsequent morbidity. Several approaches are used to reach the pineal region. The supracerebellar infratentorial approach is the commonly approach used for such lesions. OBJECTIVES: This work describes adding a paramedian expansion to the "classical median supracerebellar infratentorial approach" for posterior third ventricular and pineal region lesions with lateral expansion...

STUDY QUESTION: In which cases is freezing of ejaculated sperm indicated before ICSI? SUMMARY ANSWER: Sperm freezing should be performed only when out of two analyses at least one total sperm count in the ejaculate is lower than 10(6). WHAT IS KNOWN ALREADY: Due to variations in individual sperm parameters, in cases of severe oligozoospermia there is a risk of absence of spermatozoa on the day of ICSI, leading to cancellation of the attempt...

BACKGROUND: Atypical teratoid/rhabdoid tumors (AT/RTs) are highly malignant neoplasms that rarely occur in adults. Due to the complex histology of AT/RTs, the differential diagnosis of these tumors is quite challenging and increasingly relies on demonstration of characteristic SMARCB1/INI1 inactivation in tumor cells. CASE DESCRIPTION: A 51-year-old man presented with diplopia, lethargy, and memory deficit owing to Parinaud syndrome and hydrocephalus. Magnetic resonance imaging revealed a T2-hyperintense and homogeneously enhancing tectal mass that extended to the pineal region...
