Giant fusiform aneurysms at the basilar trunk tend to have a poor natural history and surgical management for these aneurysms remains controversial. For these aneurysms, basilar trunk occlusion with endovascular coiling is difficult when the collateral supply from the carotid circulation is relatively poor. Interestingly, we herein present a successfully treated case of a partially thrombosed giant fusiform aneurysm at the basilar trunk with relatively poor collateral supply using endovascular coil occlusion following bypass surgery (superficial temporal artery-radial artery-superior cerebellar artery anastomosis).

Juxtafacet cysts are implicated in neural compression. Thus far, it is known that surgical removal is the definitive treatment for symptomatic juxtafacet cyst because spontaneous regression is rare, and the failure rate of conservative treatment is high. We have reported a rare case of right-sided juxtafacet cyst development after the spontaneous resolution of contralateral left-sided facet cyst. The left-sided facet cyst resolved spontaneously without surgical treatment, but a juxtacyst developed on the contralateral facet on the right side, as illustrated on 4-year follow-up magnetic resonance images. To the best of our knowledge, this is the first report of newly developed contralateral juxtafacet cyst after spontaneous regression. Herein, we have discussed the natural history and the management of this rare case.

Cysts of thoracic duct are uncommon. The most commonly involved site is the thoracic segment of the thoracic duct followed by the abdominal and cervical segments of the thoracic duct. To date, about 15 cases of cervical thoracic duct cysts have been described in the literature. Information regarding the natural history of these cysts and their pathogenesis is limited. The primary symptom and sign are generally a palpable soft left supraclavicular swelling. We report a case of cervical thoracic duct cyst with a review of literature.

Congenital hemangioma (CH) is a fully formed benign vascular tumor at the time of birth and do not proliferate in postnatal life. CH must be differentiated from infantile hemangioma. CH has three subtypes that are recognized based on their natural history: Rapidly involuting congenital hemangioma (RICH), non-involuting congenital hemangioma (NICH), and partially involuting congenital hemangioma (PICH). It is important to distinguish RICH from NICH because RICH spontaneously regresses but NICH does not. Herein, we report two patients diagnosed with RICH and NICH, respectively. We presented the clinical features as well as ultrasonographic and histologic findings to distinguish congenital from infantile hemangioma.

Appropriate clinical decision making for the management of any asymptomatic vascular malformations requires an accurate assessment of the natural history of the lesions and the risks inherent in the treatment of the condition. To obtain the more information about decision making for the management of asymptomatic vascular malformation, this article discusses about guideline of the management of those lesions based on the author's experiences and review of the literatures.

Involvement of both testes in disseminated malignant lymphoma is unusual case. Lymphoma of the testis is the most common testicular tumor in patients more than 50 years old. Including all age groups lymphoma of the testis is the most common simultaneous bilateral testis. Although the natural history of lymphoma of the testis is variable, 90 percent of the patients die of generalized lymphoma within 2 years. This report concerns a case of the bilateral involvement of both testes by malignant lymphoma.
