“…We found only four cases to have been reported pre- (Table 1). [12][13][14][15] The current case report is the first in which details of MRI findings are described. The key to diagnosing hemangioblastoma on MRI is to find those abnormally enlarged vessels outside the tumor mass shadow.…”

We report a rare case of hemangioblastoma existing in the intradural extramedullary location diagnosed by magnetic resonance imaging (MRI) examination alone. A 46-year-old man gradually developed numbness in his lower extremities. MR images revealed a tumor shadow located posterior to the spinal cord at C5-C7. Small signal void shadows were continuously observed from C1 to C5 in the region cranial to the tumor, indicating the presence of enlarged vessels. Under microscopic observation, the tumor with accompanying vessels was resected totally via hemilaminectomy. The postoperative course was uneventful, and MR images obtained 4 months after the operative procedure demonstrated total removal of the tumor and the abnormal vessels. In this case, recognizing the abnormally enlarged vessels outside the tumor mass preoperatively led us to the correct diagnosis on MR images.

“…Haemangioblastoma is an uncommon neoplasm in humans, usually located in the cerebellum but can occur in all parts of the central nervous system . Spinal cord localisation of a haemangioblastoma is unusual; most clinical reports of the disease in humans describe intramedullary tumours, whereas intradural extramedullary growth is extremely rare . These tumours represent approximately 2–10% of all spinal cord neoplasms in people and can occur sporadically or as a part of the Von Hippel‐Lindau syndrome …”

Intradural–extramedullary haemangioblastoma with paraspinal extension in a dog

Haemangioblastoma is an extremely rare neoplasm in animals and only two cases of this tumour have been reported, but in other anatomical locations. Haemangioblastomas in human patients are more commonly located in the cerebellum and intradural-extramedullary growth is extremely rare. The dog in this study responded favourably to combined surgery and metronomic chemotherapy and was clinically normal 1 year after surgery.

“…Previous case reports showed that the average age of patients with extramedullary hemangioblastoma was greater than the average age of patients with all types of hemangioblastomas, with most patients in their 50's (46–66 years) [ 13 15 16 17 18 19 ]. In our study, the patients with extramedullary hemangioblastoma were 54 and 81 years old.…”

Study DesignRetrospective case series.PurposeTo investigate the relationship between tumor location and clinical characteristics.Overview of LiteratureHemangioblastoma is a rare disease that develops in the central nervous system. Magnetic resonance imaging (MRI) is useful to evaluate hemangioblastomas. Hemangioblastoma's location is designated as intramedullary, intramedullary+extramedullary, or extramedullary by MRI.MethodsWe analyzed 11 patients who underwent surgery for spinal hemangioblastoma. Using T1 contrast axial MRI data, the cases were divided into three groups (intramedullary, intramedullary+extramedullary, and extramedullary). Patient demographics, MRI findings, and preoperative neurological status were analyzed and compared for each group.ResultsThe average age of patients with intramedullary, intramedullary+extramedullary, and extramedullary hemangioblastoma was 34.0, 64.4, and 67.5 years, respectively. Patients in the intramedullary hemangioblastoma group were younger than the other groups. Extramedullary cases had a smaller syrinx compared to the other groups.ConclusionsAge may play an important role in the hemangioblastoma tumor location and the subsequent diagnosis by an MRI.
