Hemangioma of Spleen: A Rare Benign Tumor

A splenic hemangioma is a rare, benign primary tumor of the spleen. It is typically small in size (≤4 cm) and can be either capillary or cavernous in nature [1]. These tumors are often discovered incidentally during imaging studies for unrelated reasons, but they have been associated with spontaneous rupture in some cases.

Characteristics

• Size: Splenic hemangiomas are usually relatively small, measuring ≤4 cm in diameter.
• Type: They can be either capillary or cavernous in nature.
• Incidence: These tumors are uncommon and account for a small percentage of splenic lesions.
• Association with rupture: There is a risk of spontaneous rupture associated with splenic hemangiomas.

Demographics

• Age: Splenic hemangiomas can occur at any age, but they are more commonly found in adults.
• Sex: There is no significant sex predilection for this condition.

Clinical Presentation

• Asymptomatic: Many splenic hemangiomas are asymptomatic and discovered incidentally during imaging studies.
• Symptoms: When symptoms do occur, they can include abdominal pain, splenomegaly (enlarged spleen), and pancytopenia (reduction in all blood cell types).

Treatment

• Splenectomy: The standard treatment for splenic hemangiomas is surgical removal of the spleen.
• Embolization: In some cases, embolization may be considered as an alternative to surgery.

Common Signs and Symptoms of Hemangioma of Spleen

Hemangiomas of the spleen are typically asymptomatic, but in some cases, they can cause various symptoms depending on their size and location. Here are some common signs and symptoms associated with splenic hemangiomas:

• Splenomegaly: Enlargement of the spleen, which can lead to abdominal discomfort or fullness [4][12]
• Abdominal pain: Pain in the upper right quadrant of the abdomen, which can be caused by the growing tumor [8][14]
• Dyspnea: Shortness of breath, which can occur if the hemangioma is large and compresses nearby organs [4][5]
• Diarrhea or constipation: Gastrointestinal symptoms that can be caused by the compression of nearby organs or nerves [4][5]
• Spontaneous rupture: A rare but serious complication where the hemangioma ruptures, leading to severe bleeding and potentially life-threatening consequences [1][6]

It's essential to note that many splenic hemangiomas are discovered incidentally during imaging for unrelated health issues. However, if symptoms do occur, it's crucial to seek medical attention promptly.

Diagnostic Tests for Hemangioma of the Spleen

Hemangioma of the spleen, a benign vascular tumor, can be challenging to diagnose due to its asymptomatic nature and similarity in appearance to other splenic lesions. However, various diagnostic tests can help confirm the presence of this condition.

• Imaging Studies: Imaging tests are essential for diagnosing hemangioma of the spleen. The most useful imaging test available today is the computed tomography (CT) scan [6]. CT scans can help identify the characteristic features of splenic hemangiomas, such as their hypointense appearance on T1-weighted images and hyperintensity on T2-weighted images [4].
• Magnetic Resonance Imaging (MRI): MRI is considered a great tool for diagnosis and identification of splenic diseases, including splenic hemangiomas [5]. MRI can provide detailed images of the spleen and surrounding tissues, helping to confirm the presence of a hemangioma.
• Ultrasound: Ultrasound imaging can also be used to diagnose splenic hemangiomas. In one reported case, ultrasound identified a suspicious lesion in the spleen that was later confirmed as a cavernous hemangioma [11].
• Histological Examination: Histological examination following surgical removal is considered the most accurate technique for establishing diagnosis [15]. This involves examining tissue samples under a microscope to confirm the presence of a hemangioma.
• Nuclear Medicine Liver Blood Pool Scan: A nuclear medicine liver blood pool scan can be

Treatment Options for Hemangioma of the Spleen

Hemangiomas of the spleen are rare and usually benign tumors, but in some cases, they may require treatment to prevent complications or manage symptoms. While surgical intervention is often considered, there are other treatment options available.

• Splenectomy: This is the most common treatment for hemangioma of the spleen, where the entire spleen is removed. However, this approach is typically reserved for symptomatic cases or when there is uncertainty about the diagnosis [1][2].
• Laparoscopic partial splenectomy (LPS): This minimally invasive surgery involves removing only the affected part of the spleen, preserving as much healthy tissue as possible [5]. LPS has been widely regarded as an ideal spleen-preserving surgery.
• Embolization: In some cases, embolization of the splenic arterial branch may be considered to reduce blood flow to the tumor and prevent rupture [6].
• Preoperative partial splenic embolization plus laparoscopic partial splenectomy: This approach involves preoperative embolization followed by laparoscopic surgery to remove the affected part of the spleen. A case report in 2024 highlighted the effectiveness of this treatment option [8].

It's worth noting that small hemangiomas may not require any treatment and can be monitored over time with regular follow-up imaging [11]. However, if there is uncertainty about the diagnosis or symptoms persist, further evaluation and potential treatment may be necessary.
