ABSTRACTCombined clinical presentation of hemifacial spasm and ipsilateral trigeminal neuralgia is also known as painful tic convulsif (PTC). It is a rare condition and the most common cause is vascular compression. Vertebrobasilar dolichoectasia (VBD) is characterized by dilated and tortuous vertebral and basilar arteries. VBD is an uncommon and rarely reported cause of PTC. Magnetic resonance imaging (MRI), due to its inherent excellent contrast resolution, is an excellent modality for demonstrating the nerve compression by dilated and tortuous vessels seen in this condition. For this purpose, 3D MRI sequences are especially useful like constructive interference in steady state (CISS) and MR angiography. Both of these have been reported to be helpful in the diagnosis of this condition. We report a case of PTC in which we were able to document facial and trigeminal nerve compression by VBD on MRI, using CISS and time-of-fl ight MR angiography.

We presented a case of drug-resistant trigeminal neuralgia attributed to vertebrobasilar dolichoectasia, a rare condition characterized by enlargement, tortuosity, or elongation of intracranial arteries. Dolichoectatic vessels can cause dysfunction of cranial nerves through direct vascular compression. The relationships of vertebrobasilar dolichoectasia with the particularities of neurovascular conflict and images findings are discussed.

AbstractA 46-year-old man presented with clinical signs of nerve compression syndrome of his right ulnar nerve as confirmed by nerve conduction studies. Unexpectedly, clinical examination and magnetic resonance imaging (MRI) revealed a subcutaneous tumor of 5×2 cm above the ulnar groove. Surgical exploration and histopathology of biopsies demonstrated the nerve distended and entrapped into an eosinophilic, inflammatory tissue. This rare condition is consistent with localized eosinophilic fasciitis, with no systemic manifestations. There are reports of isolated forearm versions of the disease. However, none occurred with the entrapment of a peripheral nerve appearing as a peripheral nerve tumor, yet. Consequentially, the presented patient would not have benefitted from further surgical neurolysis or tumor debulking, as eosinophilic fasciitis is an inflammatory and systemic disease. The patient’s symptoms decreased spontaneously after 4 weeks of postsurgical treatment, including nonsteroidal anti-inflammatory drugs (NSAIDs). Altogether, this case proved the necessity to regard even rare diseases as a potential cause of entrapment of peripheral nerves. This should lead surgeons to critical, differential diagnostic thinking and suggest that systemic diseases may be encountered during surgery due to their capability to mimic peripheral nerve tumors.

Introduction. A glomus tumor is a benign vascular tumor derived from glomus cells and occurs mainly in the subcutaneous layer of the subungual or digital pulp. Extradigital glomus tumors have been reported within the palm, wrist, forearm, foot, bone, stomach, colon, cervix, and mesentery. Glomus tumors can originate from the intraosseous, intramuscular, periosteal, intravascular, and intraneural layers. However, a glomus tumor originating from the intravascular layer of the forearm is a rare condition.Case Report. A 44-year-old woman had a 7-year history of chronic pain and focal tenderness of the forearm. No hypersensitivity or sensory alterations were observed. Contrast magnetic resonance imaging (MRI) showed a mass measuring 5 × 3 × 2 mm leading to a vein. Surgical excision was performed, and the tumor was completely resected. Finding of gross examination revealed a dark-red, well-defined soft tissue tumor, and histologic examination confirmed that the mass was a glomus tumor. The patient’s symptoms were completely resolved postoperatively.Conclusion. Intravascular glomus tumors rarely occur in the forearm; therefore, a thorough physical exam, comprehensive medical history, in-depth imaging, and early surgical excision upon clinical suspicion may be helpful to prevent a delayed or incorrect diagnosis.

Background Giant tumefactive perivascular spaces (PVSs) are uncommon benign cystic lesions. They can imitate cystic neoplasms. Purpose To evaluate the contribution of advanced neuro magnetic resonance imaging (MRI) techniques in the diagnosis of giant tumefactive PVSs and to further characterize these unusual cerebral lesions. Material and Methods The MRI scans of patients with tumefactive PVS diagnosed between 2010 and 2019 were retrospectively reviewed. All imaging studies included three plane conventional cerebral MRI sequences as well as precontrast 3D T1 MPRAGE, post-gadolinium 3D T1 acquisitions, sagittal plane 3D T2 SPACE, diffusion-weighted imaging, and time-of-flight (TOF) angiography. Some patients received perfusion MR, MR spectroscopy, diffusion tensor imaging (DTI), and contrast-enhanced TOF MR angiography. Results A perforating vessel was demonstrated in 16 patients (66.7%) by TOF imaging. In four patients, there were intracystic vascular collaterals on contrast-enhanced TOF MR angiography. Septal blooming was observed in four patients in susceptibility-weighted imaging. On perfusion MR, central hyperperfusion was observed in four patients, and peripheral hyperperfusion was observed in one patient. On MR spectroscopy, choline increase was observed in two patients, and there was a lactate peak in three patients, and both a choline increase and lactate peak in one patient. On DTI, there was fiber distortion in five patients and fiber deformation in one patient. Conclusion Advanced MRI techniques and 3D volumetric high-resolution MRI sequences can provide a valuable contribution to the diagnosis and can be successfully used in the management of these lesions.

SUMMARY Vertebral Artery Dissection (VAD) is a rare condition that can be caused by a wide amplitude of neck movement, which injures the vessel wall and can cause ischemia in the cerebellum. We present a 37-year-old man with herniated lumbar disc and allergic rhinosinusitis, which caused sneezing spells. After one of these bouts with a ricochet of the head, he presented C3 misalignment with local pain. Twenty-one days later, affected by a new crisis, he presented left temporal headache, nystagmus, and vertigo. After 3 days, Magnetic Resonance Imaging (MRI) identified 2 regions of cerebellar ischemia and filling failure of the right vertebral artery. After 2 days, Computed Angiotomography (CT Angiography) was performed and showed right VAD with a local thrombus, without aneurysmal signs. Transcranial Doppler did not indicate an increase in blood flow from this artery. The suggested treatment involved administration of anticoagulant Apixabana 5mg, 12/12h, for 3 months, until the condition was reevaluated with new Angio CT and MRI. It was recommended that the patient was released from work for 1 month and forbidden from doing intense physical exercises for 3 months; however, due to setbacks, these deadlines were extended until a new appointment, 4 months after the first visit. The new tests showed no changes, indicating that the condition was stable. This case aims to indicate the possible investigations of the diagnosis and therapeutic options of the rare association between VAD with cerebellar infarction in a well-documented case.

Spinal epidural haematoma is a rare condition, which may be due to trauma, surgery, epidural catheterisation or disorders of coagulation. We report a case of 60 year old lady who was on warfarin for Atrial fibrillation (AF) presented with history of non-traumatic sudden onset pain in both legs and difficulty in walking. Magnetic resonance imaging (MRI) spine demonstrated epidural haematoma which was treated conservatively. Another dilemma was anticoagulation for AF. We examine the options to manage such case.

Introducción: El síndrome del espacio cuadrilátero (QSS) es un cuadro clínico causado por la compresión nerviosa y/o vascular a nivel del espacio axilar lateral. La prevalencia de este síndrome se desconoce y se cree que es baja, sin embargo, formas de presentación incompleta podrían llevar a que el mismo sea subdiagnosticado. Objetivo: Describir un protocolo diagnóstico utilizado en una serie de casos consecutivos de pacientes con omalgia inespecífica y sospecha de QSS. Materiales y Métodos: De manera prospectiva se evaluaron 10 pacientes con omalgia agravada con la rotación externa forzada, uno de ellos con síntomas bilaterales. Se realizó electromiografía (EMG) de deltoides y redondo menor bilaterales, con estudios de conducción nerviosa. Los valores se compararon con el hombro sano, y con un grupo control. El diagnóstico se confirmó mediante resonancia magnética nuclear (RMN). Resultados: El EMG mostró en todos los casos atrapamiento con compromiso axonal de la rama para el redondo menor, con preservación de la inervación del deltoides. La RMN mostró en los 11 hombros afectados atrofia selectiva del redondo menor. Conclusión: El QSS en sus formas incompletas suele ser subdiagnosticado, siendo necesario mantener un alto índice de sospecha clínica frente a un cuadro de omalgia inespecífica. Palabras Claves: espacio cuadrilátero, omalgia, electromiografía, redondo menor, nervio axilar. Introduction: The quadrilateral space syndrome (QSS) has clinical features caused by a nervous and /or vascular compression at the lateral axillary space. The prevalence of this syndrome is unknown but it is believed to be low. Nevertheless, some cases with an incomplete clinical presentation might be misdiagnosed. Purpose: To describe a diagnostic protocol used in a series of consecutive cases of patients with non-specific omalgia and suspected QSS. Materials and Methods: Ten patients of both genders suffering shoulder pain aggravated by forced external rotation were prospectively evaluated.  One of them had bilateral symptoms. Evaluation included clinical examination, electromyography (EMG) and nerve conduction studies of the deltoid and teres minor bilaterally. The results were compared with an age-matched control group. Diagnosis was confirmed by magnetic resonance imaging (MRI). Results: The EMG showed in all the cases a selective entrapment of the branch for the teres minor, with preservation of the innervation of the deltoid. The RMN showed in the 11 affected shoulders selective atrophy of the teres minor. Conclusion: Incomplete presentations of the QSS are usually underdiagnosed, making it necessary to maintain a high index of clinical suspicion in front of any non-specific omalgia case. Key words: quadrilateral space, omalgia, electromyography, teres minor, axillary nerve.
