The authors define corrected dates of three remarkable events of early history of radiology in Berlin, which have been wrongly reported in the literature. Compiled evidence from contemporary newspaper publications demonstrates that Röntgen delivered his lecture to kaiser William II on 12 January 1896. Paul Spies gave a lecture on Röntgen rays to the Reichstag on 13 February 1896. The first publicly taken X-ray in Berlin was obtained on 20 January 1896.

Teaching point: Extrapelvic endometriosis involving pudendal and sciatic nerve may be a cause of lower limb pain.

Hepatic artery aneurysms (HAAs) are rare vascular malformations that can arise from atherosclerosis, trauma, or iatrogenic injury. HAAs can be symptomatic and lead to serious complications. We present the case of a patient with painless jaundice caused by obstruction of the distal common bile duct by a HAA on a replaced right hepatic artery. This was further complicated with cholangitis. After endovascular stenting of the aneurysm, cholestasis decreased. Learning point: Hepatic artery aneurysms can cause common bile duct obstruction resulting in cholestasis.

Hematocolpos, characterized by the accumulation of menstrual blood in the vagina, is a rare condition often misdiagnosed due to its uncommon occurrence and non-specific symptoms. Main causes include imperforate hymen, obstructed hemivagina with ipsilateral renal anomaly (OHVIRA), congenital lower vaginal atresia, and complete transverse vaginal septum. Without early diagnosis and treatment, complications such as tubal adhesion, pelvic endometriosis, and infertility can occur. This article reviews the differential diagnosis and treatment of hematocolpos.

Spinal pilocytic astrocytoma (PA) is a rare disorder with atypical, clinical and imaging characteristics, and generally limited to case reports. We analysed the clinical manifestations, imaging findings, treatment and prognostic follow-up of 12 patients with spinal PA admitted from January 2010 to July 2021, and reviewed the relevant literature. Radiological assessment, especially magnetic resonance imaging, can help to provide effective diagnostic information. The diagnosis and differentiation of this disease is discussed in an attempt to contribute to a more comprehensive preoperative assessment.

Carotid-cavernous fistulas (CCFs) are abnormal connections between the carotid arteries and the cavernous sinus, posing significant neuro-ophthalmologic risks. This report presents a rare case of bilateral post-traumatic CCFs, focusing on clinical presentation, diagnosis, and management. Symptoms mimic conjunctivitis, causing diplopia, exophthalmos, and ophthalmoplegia. Diagnosis relied on computed tomography, magnetic resonance angiography, and digital subtraction angiography. Management involved transarterial embolization with coils, achieving successful outcomes. This highlights the importance of timely intervention and comprehensive imaging to prevent complications. Teaching point: This case report details a rare instance of bilateral post-traumatic carotid-cavernous fistulas, emphasizing clinical presentation, diagnostic evaluation, and management.

Teaching point: Perivascular spaces, also known as Virchow-Robin spaces, are fluid-filled spaces that surround the vessel walls from the subarachnoid space through the brain parenchyma.

Teaching point: Hourglass-like constrictive neuropathy should be considered in patients with unexplained peripheral neuropathy symptoms, as imaging may show nerve constriction without evidence of intrinsic or extrinsic compression.

In hereditary leiomyomatosis and renal cell carcinoma syndrome, fumarate hydratase-deficient renal cell carcinomas typically present as aggressive, unilateral, often cystic masses with heterogeneous enhancement. These tumors can metastasize early, making appropriate imaging and staging critical for diagnosis and management. Teaching point: When a renal lesion suspected of RCC is identified in a patient with cutaneous and uterine leiomyomas, HLRCC should be evaluated, which is important for future genetic counseling.

Teaching point: Although deep vein thrombosis is a common concern after lumbar arthrodesis, rare complications such as an iatrogenic arteriovenous fistula can present similarly, highlighting the importance of a broad, differential diagnosis and appropriate imaging for timely management.
