Summary
Oculomotor nerve schwannoma, a rare cause of double vision (diplopia), was diagnosed in a 69-year-old woman. This study discusses the diagnosis and management of this uncommon condition.
Area of Science:
- Neuro-oncology
- Ophthalmology
- Neurology
Background:
- Oculomotor nerve palsy, characterized by double vision (diplopia), can stem from various causes.
- Schwannomas, typically benign nerve sheath tumors, can rarely affect the oculomotor nerve.
Observation:
- A 69-year-old woman presented with an 8-month history of diplopia and right third-nerve palsy.
- Head MRI revealed a 5.8 mm nodular lesion in the suprasellar cistern with gadolinium enhancement.
- The lesion showed no interval growth over a 3-month follow-up period.
Findings:
- The clinical presentation and MRI findings were consistent with an oculomotor nerve schwannoma.
- Oculomotor schwannomas are an uncommon etiology for third-nerve palsy.
Implications:
- This case highlights the importance of considering rare diagnoses like oculomotor nerve schwannoma in patients with third-nerve palsy.
- Understanding the presentation and management of these tumors is crucial for effective patient care.

02:07Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

03:03mTOR Signaling and Cancer Progression
4.6K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

3.4K
The neuronal supply to the gastrointestinal (GI) tract is essential for regulating various functions, including digestion, absorption, and movement of food. This intricate network of nerves is known as the enteric nervous system (ENS), often referred to as the "second brain" of the body.
The enteric nervous system consists of two major plexuses: the myenteric plexus (Auerbach's plexus) and the submucosal plexus (Meissner's plexus). These plexuses are located within the layers of...

01:21Spinal Nerves: Plexus II
2.1K
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Body:Bioequivalence experimental study designs are crucial methodologies used in evaluating and comparing the bioavailability of different drug products. These designs are categorized into various types: completely randomized, randomized block, repeated measures, cross and carry-over, and Latin square designs.Completely randomized designs involve randomly allocating treatments to all subjects participating in the experiment. This allocation is achieved by assigning unique random numbers to...

4.9K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
