Objective: The position of the patella relative to the femur is critical in the evaluation of patellofemoral joint diseases. Blumensaat defined a line to evaluate patellofemoral congruence, which is still used clinically. This study aimed to evaluate age- and gender-related changes in the blumensaat line (BL). Methods: Images of 229 patients, who underwent standard lateral knee radiography at 30° flexion, were retrospectively evaluated. The relationship between BL and interior pole of the patella was examined, and the variability of the measurements according to gender and age groups was investigated using statistical methods. Results: Two hundred and twenty-nine patients (128 men; 101 women) were included in the study. The mean age was 41.96±13.41 years (39.63±13 years for men and 44.90±12.2 years for women). BL passed through the lower pole of the patella in only two (0.9%) of the 229 patients. No statistically significant difference was found in the BL measurement of men and women (p>0.05). There was also no statistically significant relationship between age and these distance values (r=-0.112; p>0.05). Conclusion: It was concluded that there was no difference between genders and different age groups in terms of BL measurements. [ABSTRACT FROM AUTHOR]

Patients with traumatic intracranial subarachnoid hemorrhage (SAH) rarely develop spinal subarachnoid hemorrhage (SSAH) without direct spinal injury. We present the case of a 76-year-old male patient with traumatic intracranial SAH and subdural hematoma, back pain and weakness in the both lower limbs radiating to the legs three days after the trauma. After worsening of pain and numbness, the patient underwent a lumbar magnetic resonance imaging 7 days after the trauma, in which blood was seen in the spinal canal in the lumbosacral region. The bleeding was considered SSAH because of the liquid level. The patient underwent conservative treatment because the patient was found to be at high cardiac risk and the neurological deficit was mild. In patients with traumatic intracranial hemorrhage and delayed pain or neurological deficits, SSAH should be suspected in the first period of trauma. [ABSTRACT FROM AUTHOR]

Ligamentum flavum cyst, a cystic lesion adjacent to the lumbar spine, is a rare cause of neurological symptoms and signs. It is usually seen in older ages. It is more common in the lower lumbar region than in the cervical region. Here, we aimed to discuss ligamentum flavum cysts in two cases. In a 54-year-old male, a lumbar magnetic resonance imaging showed a ligamentum flavum cyst located at the right posterolateral of the spinal canal at the L3-L4 level, and spinal canal stenosis at this level. After the surgical removal of the cyst, the patient's symptoms entirely resolved. A 43-year-old female patient had a ligamentum flavum cyst on the left posterolateral of the spinal at L4-L5 level with thecal sac compression. Conservative treatment was planned, and the symptoms regressed during follow-up. [ABSTRACT FROM AUTHOR]

Hypertrophic olivary degeneration (HOD) is a rare form of transsynaptic degeneration and is the only type which occurs with hypertrophy rather than atrophy. It develops due to pathologies affecting conduction in the dentato-rubro-olivary pathway. Despite being the classic HOD-related findings, palatal tremor, Holmes tremor, nystagmus, and cerebellar ataxia are not usually present in patients. Most cases are asymptomatic, and HOD is incidentally detected on magnetic resonance imaging scans. This paper reports the case and imaging results of a 60-year-old male patient that presented with findings of acute infarction at the posterior aspect of the mesencephalon and pons and superior cerebellar peduncle following head trauma and developed right contralateral HOD.
