Abstract Background Global aphasia without hemiparesis (GAWH) is a rare stroke syndrome characterized by the dissociation of motor and language functions. Here, we present a case of GAWH with the patient later regaining speech fluency. Case presentation A 73-year-old man was admitted to our emergency department immediately after an episode of syncope. On arrival, we noted his global aphasia but without any focal neurologic signs. Computed tomography (CT) perfusion scans showed a large hypodense region over his left perisylvian area. Under the impression of acute ischaemic stroke, he received recombinant tissue plasminogen activator (rtPA) injection and was treated as an inpatient. The patient was later discharged with GAWH status and received regular speech rehabilitation. After 14 months of rehabilitation, the patient gradually recovered his language expression ability. The degree of aphasia was evaluated with the Concise Chinese Aphasia Test (CCAT), and we obtained brain single photon emission computed tomography (SPECT) scans to assess cerebral blood flow. Conclusion A patient with severe impairments of Broca’s and Wernicke’s areas was able to talk fluently despite being unintelligible. SPECT revealed relative high level of radioactivity uptake in the right frontal lobe, suggesting the deficits in speech fluency could have been compensated by the right hemisphere. Although this is a single case demonstration, the results may strengthen the role of the right hemisphere in GAWH patients and suggests additional study that examines the possible benefits of stimulating activity at right homologous regions for recovering language function after global aphasia.

Clinical features and results of neuroimagings of an 86 year old woman with the Charles Bonnet syndrome are reported. She had become completely blind bilaterally due to cataracts and glaucoma. Shortly after an operation for cataracts, she developed visual hallucinations which lasted for 22 years. She had no deterioration of intelligence. Computed tomography (CT) and magnetic resonance imaging (MRI) showed moderate generalized atrophy, particularly of the temporal lobes. A serial single photon emission computed tomography (SPECT) study during visual hallucinations demonstrated hyperperfusion in the left temporal region and the basal ganglia and hypoperfusion in the right temporal region. These findings suggest that asymmetrical blood flow, particularly in the temporal regions, may be correlated with visual hallucination in the Charles Bonnet syndrome.

Abstract We describe the operative approach and management for costotransverse joint inflammation in a 49-yr-old man with worsening midthoracic pain radiating to the right paraspinal area. He underwent physical therapy with no relief of his symptoms. Thoracic spine magnetic resonance imaging (MRI) revealed severe arthritic changes involving the right T10 costotransverse joint. Scoliosis X-rays showed a dextroconvex curvature in the midthoracic spine, without any significant imbalance. Single-photon emission computed tomography (SPECT) scan revealed focal increased uptake of the right T10 costotransverse joint. T10 costotransverse joint lidocaine injection did not provide any relief. We performed a computed tomography (CT)-guided biopsy, which was negative for malignancy and also cultures were negative. MRI revealed a significant enhancement in this area and the patient's C-reactive Protein was elevated. Decision was made to perform open biopsy and costotransverse joint resection. We present a case of minimally invasive, image-guided costotransverse joint resection, which has not been described in the literature. The right T10 costotransverse joint was dissected out with the image-guided dilator, and tubular retractors were inserted. Under the microscope, using the image-guided drill, the right T10 costotransverse joint was drilled out. The lateral aspect of the right T10 process was drilled out as well as the medial-dorsal aspect of the right T10 rib. The patient recovered from surgery well with abatement of his preoperative thoracic pain, which remained abated at 6-mo follow-up. This case highlights the complex technical nuances of this procedure, and the importance of a thorough preoperative evaluation with a bone SPECT scan to help localize the pain generator. Patient consented for the procedures and for the publication of the video.

We present a 74-year-old woman with primary hyperparathyroidism, with elevated parathyroid hormone and calcium. Tc-99m-methoxyisobutyl isonitrile (sestamibi) planar imaging showed a focus of uptake over the inferior aspect of the right submandibular gland that was localized on the single-photon emission computed tomography with CT.

Background. Outpatient care is not widely spread in modern dacryology. At the same time, its necessity increases. There are no evidences of balloon dacryoplasty (BDP) application in Russian periodical literature. Material and methods. 50 surgical procedures in 30 patients with partial nasolacrimal duct obliteration were performed, among them 30 BDP without lacrimal pathways intubation (group 1) and 20 with bicanalicular Ritleng intubation of lacrimal pathways (group 2). Lacrimal scintigraphy, single photon emission computed tomography, combined with X-ray computed tomography, subjective tearing estimation in points, and health depending quality of life evaluation wre performed in all cases. Same tests were repeated in 3 months after surgery. Results. A positive outcome rate was 90 % in both groups. There were no complications in group 1. A single case of stent dislocation was recorded in group 2. Conclusion. BDP is an effective procedure in dacryostenosis of the lacrimal pathways vertical part obliteration. This procedure helps to avoid complications associated with long stent retention. It is possible to get good functional results even at short term after BDP surgery, and there is a possibility for this procedure to be carried out in an outpatient setting.

We report a case of bone metastasis arising from lung cancer, including quantitative values obtained with bone single-photon emission computed tomography/computed tomography (SPECT/CT), which were useful to evaluate the treatment response. The first bone SPECT/CT during pembrolizumab therapy for lung cancer recurrence showed intense 99mTc-HMDP uptake of the right femur head and mild uptake of the left ribs. After the palliative radiotherapy for the right femur head metastasis and chemotherapy, the second bone SPECT/CT showed a decrease in focal uptake of the right femur hip and increasing uptake of the left ribs. There was also new uptake appearance in the sternum, right rib, spine (Th2, Th9, Th12, L4, S1), and bilateral pelvic bone (left ilium, acetabular cartridge, femur, right ilium and ischium). The change of maximum standardized uptake values (SUVmax) for the right femur head and left third and eighth rib bony metastases were −72.6% (from 22.96 to 6.28), +407.7% (from 2.97 to 15.08), and +229.2% (from 2.60 to 8.56), respectively. The change of whole-lesion metabolic bone volume and total bone uptake was +235.4% (from 22.75 to 76.3 cm3) and +219.1% (from 205.0 to 654.09), respectively. Two quantitative bone SPECT/CT images clearly showed the good response of femur head metastasis due to radiotherapy, and progression of other bone metastases regardless of chemotherapy.

Havaki-Kontaxaki BJ, Ferentinos PP, Kontaxakis VP, Kontaxaki M-I V, Geronikola X, Armeniakos I, Papadimitriou GN. Low-dose clozapine monotherapy for recurring episodes of depression, hypersomnia and behavioural disturbances: a case report.Case Report: We present a 27-year-old woman who manifested recurrent episodes of hypersomnia, compulsive hyperphagia, hypersexuality, impulsive behaviours, irritability and depressive mood since the age of 13 after a viral febrile infection. She had 3–4 episodes/year lasting from a few days to 2–3 weeks which were managed with various psychotropics. During her last episode, she was admitted because of persistent behavioural disturbances. Brain 99m-Tc-ethyl cysteinate dimer single-photon emission computed tomography scans showed bilateral mesiotemporal and thalamic hypoperfusion, more significant in the right hemisphere. While hospitalised, she developed neuroleptic malignant syndrome following haloperidol administration. She was discharged on clozapine 100 mg/day. Over the following 30 months, she remained symptom free on clozapine 50–100 mg/day.Discussion: Differential diagnosis included either an atypical recurrent mood disorder with hypersomnia and behavioural disturbances or Kleine–Levin syndrome.Conclusion: Low-dose clozapine monotherapy may worth being further investigated for the management of recurring episodes of depression, hypersomnia and behavioural disturbances.
