Initial abdominal CT scan indicated a small bowel obstruction with a transition point at the jejunal area [Figure 1].
(a-d) Immunohistochemical analysis of malignant lymphoma infiltrating mucosa and submucosa of small Intestine. The Ki-67 showed a markedly increased proliferative index, with 90% of lymphocytes staining positive

Immunohistochemical analysis for Ki-67 showed a markedly increased proliferative index, with 90% of lymphocytes staining positive [Figure 2].
(a) Positron emission tomography (PET)/CT scan from her skull to mid-thigh, which indicated no hypermetabolic lesions suggestive of active malignancy in the skull base or neck. (b and c) Brain magnetic resonance imaging (MRI) demonstrated a single ill-defined, irregular, right fronto-parietal enhancing lesion surrounded by vasogenic edema, with associated mass effect and midline shift

Brain MRI demonstrated a single ill-defined, irregular, right fronto-parietal enhancing lesion surrounded by vasogenic edema, with associated mass effect and midline shift [Figure 3].
(a, b) Post-operative MRI demonstrated the resection of the right frontoparietal mass with small air fluid level and residual blood product seen at the tumor bed

She underwent surgical resection of the intracranial lesion, and post-operative MRI demonstrated the resection of the right frontoparietal mass with small air fluid level and residual blood product seen at the tumor bed [Figure 4].
Histopathologic evaluation of the lesion biopsy confirmed the diagnosis of metastatic EATL involving the brain
