Background
Radiation-induced organizing hematoma (RIOH) is a sporadic form of cavernous hemangioma (CH) that occurs after cerebral radiation. RIOH lesions are distinct histologically from de novo CH; however, detailed research on this subject is lacking. In the present study, the clinical and histological features of RIOHs were evaluated based on causative lesions.
Methods
The present study included 37 RIOHs confirmed by surgical excision from January 2009, to May 2020, in Yonsei Severance Hospital. All cases were divided into subgroups based on type of radiation treatment (gamma knife surgery [GKS], n = 24 vs. conventional radiation therapy [RT], n = 13) and pathology of the original lesion (arteriovenous malformation, n = 14; glioma, n = 12; metastasis, n = 4; other tumors, n = 7). The clinicopathological results were compared between the groups.
Results
Clinical data of multiplicity, latency, and size and wall thickness of the original tumors and RIOHs were analyzed. The GKS group showed shorter latency (5.85 ± 4.06 years vs. 11.15 ± 8.27 years, p = .046) and thicker tumor wall (693.7 ± 565.7 μm vs. 406.9 ± 519.7 μm, p = .049) than the conventional RT group. Significant difference was not found based on original pathology.
Conclusions
RIOH is more likely to occur earlier with thick tumor wall in subjects who underwent GKS than in patients who underwent conventional RT. These results indicate the clinical course of RIOH differs based on type of treatment and might help determine the duration of follow-up.

Abstract PDF

Cavernous hemangioma of the uterus is an uncommon mesenchymal tumor. Most cases have been reported in young, pregnant women and the condition is very rare in a postmenopausal patient. An 81-year-old woman presented with a huge pelvic mass. Abdominal computed tomography and magnetic resonance imaging results suggested a leiomyoma with degenerative change and hemorrhage. Microscopically, large, thick-walled and variable-sized vascular channels were evident in the majority part of myometrium; the lining cells were immunohistochemically reactive for CD31. Vascular tumors of the female genital tract should be cautiously excised due to the profuse intra-operative bleeding. The pathological examination of a hysterectomy specimen is the only method to confirm the diagnosis of this tumor.

Abstract PDF: Hemangioma of the kidney is a relatively uncommon tumor, which is most commonly located in the tip of the papilla. This lesion is usually small and has been found incidentally at postmorten examination. About 200 cases of renal hemangioma have been reported since Virchow's original report in 1876. In renal hemangioma, cavernous hemangioma is the most common type. They can create diagnostic problem for the clinician and the radiologist. We experienced a case of renal cavernous hemangioma in the medulla of the upper pole. The patient was a twenty-seven-year-old male who had gross hematuria and right flank pain. A nephrectomy was performed. An ill-defined mass, 4.5x3.0x1.5 cm, was observed around the pelvis. Microscopically, the tumor mass was hemangioma of the cavernous type.
